How Long To Grow Cannabis From Seed

How Long Does It Take to Grow Weed Indoors? [3 to 5 months] This is one of the most common questions we receive from curious soon-to-be indoor cannabis growers: How long does it really take to From germination to curing, understanding each stage of the cannabis growth cycle is vital to achieving a healthy cannabis crop. The time it takes to grow cannabis indoors varies depending on several factors. Read our guide on cannabis growth timescales, with helpful tips along the way!

How Long Does It Take to Grow Weed Indoors? [3 to 5 months]

This is one of the most common questions we receive from curious soon-to-be indoor cannabis growers: How long does it really take to grow weed? What’s the growing timeline?

It’s actually a really good question! Every new marijuana grower should know how much work they’re signing up for! The short answer is…

The Average Indoor Cannabis Grow Takes 3-5 Months

The long answer is: from Day 1 of your weed plant’s life to actually smoking your harvest, it can take… 8 weeks – 7+ Months! That’s a huge range, right?

That’s why most cannabis growers won’t give you a straight answer. The truth is, there are many factors will affect the total time until you have ‘ready’ buds, by days, weeks or even months. This includes your strain, your setup, and how big you plan to grow your plants (bigger plants need more time!). So instead of giving you a huge range, an easier-to-swallow answer might be to say that the average grow takes 3-5 months for indoor growers.

This includes the time needed to grow your cannabis plant from seedling to harvest plus an additional 2 weeks (or more) which is used to cure your cannabis buds after harvest (making them more potent and better smelling).

Additionally, for at least the first time you grow, you also need to consider the time needed to get your equipment and seeds/clones.

This article will give you the total time breakdown, so you can plan out the details of your grow in order to achieve the harvest times you desire:

Ultimately, How Long to Harvest Marijuana Depends on the Desired Yields, Strain and Grow Style

Today I will show you how to plan your grow so it takes the amount of time you want!

Note: When growing cannabis indoors, it takes 3-5 months on average to go through the life cycle of a plant. When growing outdoors, the total time depends on your local climate as most strains are ready to harvest in mid-to-late Autumn.

  2. Time Needed to Grow Weed, From Seedling to Harvest
  • Germinate Your Seeds (1-7 days) – Learn about fail-proof methods to germinate perfectly in soil/coco or hydro.
  • Vegetative Stage (average 4-8 weeks, length based on desired plant size) – In the vegetative stage, the cannabis plants are growing just stems and leaves. On average, most indoor growers vegetate their plants for 4-8 weeks. Seedlings are able to start flowering as early as 3 weeks from germination, but the resulting plants will be tiny. Most growers choose to let plants vegetate for longer because giving them more time to grow results in bigger plants, which tend to produce bigger yields as long as you have enough light to cover all the bud sites. That being said, you can still produce quite a bit of bud with a lot of small plants growing at once as long as you fill up your grow space.
  • Flowering Stage (average 8-10 weeks, depends on strain) – This is when plants start making buds. The length of the flowering stage depends heavily on the strain/genetics, with an average of about 8-10 weeks for most strains. Some strains are bred to have very short flowering stages (for example, most auto-flowering strains will naturally start flowering at around 3 weeks old and some are ready to harvest just 5 weeks later, for a total of only 8 weeks from seed!). Other strains take months in the flowering stage before they’re ready to harvest. Typically, longer-flowering strains produce higher yields and short-flowering ones tend to produce lower yields. Buds that are exposed to more light-hours have more time to fatten up, though that’s not always the case.
  1. Post-Harvest (This is when the smell/taste/look you love shows up) (1-2+ weeks) – After buds are harvested, they are dried for about a week then placed in glass jars to “cure” for 2+ weeks in order to achieve the best quality. This post-harvest processing dramatically improves the taste, smell and the perceived potency of the buds. It also reduces the chance of buds causing headaches or unpleasant “speedy” effects. Don’t skip this step! It will account for nearly 50% of your final bud quality! Learn how to dry & cure your buds to perfection.

If you choose the right strain, you could be smoking your own buds as soon as 3 months from germination!

Before You Start Growing Weed

Total preparation time needed: Up to a few weeks

Here’s the breakdown…

Get equipment: 0 days – 2 weeks
This includes purchasing your equipment and/or waiting for it to show up in the mail. This goes much quicker if you buy everything locally, for example at a hydroponics shop. Once you have your marijuana growing supplies, you’ll need to setup your growing area and equipment. A standard setup should take an afternoon at most. Depending on how you purchase your equipment and how quickly you setup, you could be ready the same day or in two weeks (after factoring in shipping time).

Check out examples of new grower shopping lists to learn exactly which supplies you’ll need.

Get seeds or clones: 0-4 weeks:
If you’ve found seeds in your bud or have instant access to genetics (like knowing a grower or buying seeds/clones locally), you’re already good to go. If you order from a seed bank overseas (especially US residents), expect to wait 1-4+ weeks to get seeds. Shipping time depends on the shipper and how fast the mail gets delivered. Sometimes seeds get caught up in customs for weeks. Make sure to always order from a trustworthy vendor.

Time Needed to Grow Weed, From Seedling to Harvest

Total growing time needed: 3-5 months on average

Here’s the breakdown…

Seedling Stage
Germinate your seeds: 1 – 7 days
Seedlings can sprout in as little as a day, but by 3-5 days, they should be good to go. If you have access to clones, you get to skip this wait.

Learn my fail-proof method to germinate your seeds in soil/coco or hydro.

Vegetative Stage
Vegetative Stage: 4-8 week average (but if you want big plants it may take longer)
The length of this stage is a matter of personal preference. Most cannabis plants won’t start flowering until they’re at least 3 or 4 weeks from germination, but after that you get to choose how long your plant spends in this stage (except auto-flowering strains, which automatically start flowering in 3-4 weeks from seed). Except for auto-flowering strains, you have total control over the vegetative stage because you’re the one to ‘flip the switch’ and get your plant to enter the next life stage: flowering.

When you start with a seed, even with an auto-flowering plant, you will always have at least 3-4 weeks of vegetative growth before any buds start forming no matter what you do. Growers generally allow their plants to stay in the vegetative stage from a few weeks to a few months.

The size your plant achieves in the vegetative stage has a very large effect on your final yields since bigger plants produce more bud sites than smaller plants. However, you need enough light to cover all the bud sites or they will never develop properly. Light is like food for bud growth!

These vegetating plants are about 4 weeks old from germination

To give you an idea as to what your FINAL marijuana plant may look like depending on how long it spends in the vegetative stage…

This plant didn’t spend any time in the Vegetative Stage. It was given 12-12 lighting almost immediately after sprouting. It’s so small that it spent its whole life in a solo cup, and its only light came from CFLs. I weighed down the bottom of the cup so it didn’t fall over. It ended up yielding about 0.75 oz.

These auto-flowering plants spent about 3 weeks in the vegetative stage before they automatically started flowering, and were ready to harvest just 5 weeks later. They were about a foot tall at harvest and yielded approximately 2 ounces each. Read the step-by-step tutorial to grow plants exactly like this.

This marijuana plant spent about 6 weeks in the vegetative stage before being changed over to flowering and yielded just over 6 ounces at harvest. View the complete grow journal with instructions on how to grow your plant so it looks just like this at harvest!

These cannabis plants were vegetated for about 8 weeks before being flipped to the flowering stage. Although they were grown in the exact same conditions from seed to harvest, their final heights are remarkably different because their strains had vastly different genetics. The smaller plant produced 6.6 ounces, while the big plant produced 9.3 ounces. Strain can make a big difference! Learn about growing different strains together.

These cannabis plants were vegetated for about 9 weeks before being flipped, in the exact same setup as above, and produced over 10 ounces each. Besides an extra week of veg, the biggest difference between this grow and the one above was simply the strains.

This human-sized plant (one of my very first plants) spent a little more than 3 months in the vegetative stage before I realized I needed to turn it over to the flowering stage. It then spent another 12 weeks in the flowering stage before it was ready to harvest because it was a long-flowering strain. It got way too tall for its space (taller than me!) and started falling over. However, despite the huge size and more than 5 months of growth, it only ended up yielding about 6 ounces. This is because it was under weak CFL grow lights. Though there were a lot of buds, the lack of strong light made them airy, without a lot of weight. Click the picture for a close-up.

Some people put their seedlings or clones right into the flowering stage if they want to harvest quickly though this makes for extremely small plants. For example, super-stealth growers who are growing in small hidden spaces – like out of a computer case – would want to put their seedlings into flowering nearly right away to keep their plants as small as possible. It’s also important to remember that container size and grow lights make a big difference. Small containers constrain the roots and keep plants from getting as big as they could, and small lights prevent buds from fattening up as much as they could.

I personally recommend at least 4 weeks in the vegetative stage with 18+ hours of light each day for the best results. Plants that are forced to start flowering sooner than 4 weeks don’t yield much compared to how much work you put in. That being said, keeping plants relatively small does have some benefits!

A good rule of thumb…

Your plant will likely double in size (maybe a bit less, maybe more) from when you first put it into the flowering stage; this is known as the Flowering Stretch. So make sure you end the vegetative stage before your plant reaches half the final height you want, or your cannabis plants may outgrow your grow space during the flowering stage!

Flowering Stage
Flowering Stage: (average 8-10 weeks, length depends on the strain/genetics)

Here’s the breakdown…

  • Week 1-3 – Transition to Flowering
  • Week 3-4 – “Budlets” Form
  • Week 4-6 – Buds Start Fattening Up
  • Week 6-8 – Buds Ripen, Pistils Darken – some strains spend longer in this stage
  • Week 8-12+ – Flowering Ends, Harvest time!

The length of time needed to stay in the flowering stage depends heavily on the strain. Once you have switched your plant into the flowering stage they will stretch (the ‘flowering stretch’), form buds and then fatten.

Here’s a list of some of my favorite and best cannabis strains by the length of the flowering period:

Short (6-8 weeks)

    – Known for being especially easy to grow – High-yielding, medical, high-CBD, medium-THC strain – Based on the famous White Widow strain but with a much faster finish – This version of Blue Cheese is fast flowering and easy to grow, yet buds are extra potent and produce great effects – One of the best strains for outdoor growing (and buds may turn pink or bright purple!) – A gem by Barney’s Farm, this strain “lifts you up” and causes a strong “head high” that can be a great way to relax after a tough day, or for when you want to get in a creative mood. – One of the most potent auto-flowering strains I’ve grown so far, ready in about 10 weeks from germination (7-week flowering stage) and just overall a healthy, easy, and high-yielding plant.
  • In fact, if you’re interested in a very short flowering time, most auto-flowering strains are ready to harvest less than 3 months from seed.

Frisian Dew plant growing outdoors with deep purple buds

Medium (8-12 weeks)

    – I just finished a grow with this strain and it impressed me. The buds did not turn purple but the smell, yields, and potency of buds were outstanding. – Medical strain, has a THC:CBD ratio of 1:1 – An award-winning strain that’s fruity, vigorous, and potent. The yields are not necessarily the highest, but it’s worth it for the quality of buds. I’ve grown this strain in many different setups and buds always come out great. – An award-winning strain that’s curiously strong. It’s one of the few “haze” cannabis strains that doesn’t take forever to finish flowering. – A cross between Gelato and OG Kush; two extremely popular strains in the US on the west coast. Finishes on the faster side, yet still produces great yields, potency, and smell. – Another beautiful Gelato cross, this time with the famous Gelato 33 clone (a very specific cut of Gelato), with Wedding Cake. – Another west coast favorite, this produces beautiful buds that are covered in crystals/trichomes, also high yielding. – Yields were so-so yet buds produce powerful effects. It turned a bit purple when I grew this strain (pictured below in the middle), which was a delightful surprise, but the potency is what I remember. – Easy to grow. Wants higher levels of nutrients in the flowering stage but rewards you with big yields, a strong spicy smell, and great potency.

Long: (12-14+ weeks)

  • Many Haze strains, as well as some Sativa strains, and generally any strains that originated near the equator. – A cross between some of the best Haze strains in Southeast Asia. If you want to try something different that is almost impossible to find in the US or Europe, this is it. It produces psychedelic effects that defy its cannabinoid content. May be too intense for some people.

In general, most strains (besides auto-flowering strains) are in the medium range as far as how long they take to flower.

It’s not exact – There’s a 2-3 week harvest window for most plants, and keeping your plants in the flowering stage for a bit longer tends to increase your yields. This is because the plants tend to really bulk up their flowers once they’ve become ‘ripe’.

So often times, even though you could harvest at the shortest recommended time, waiting an extra week or two will give you 10-30% more yield compared to harvesting as early as possible.

Utopia Haze is a mix of Brazilian landrace strains

Post-Harvest (before you smoke you should do this stuff too)

Total post-harvest time needed: 2.5 weeks – 1.5+ months

Drying: 4 – 10 days
Good marijuana buds can be dried in as little as 4 days, but ideally, drying should be a slow process taking up to a week or more. Making sure your plants have been thoroughly dried (but not over-dried) will lower chances of mold during the curing process.

Curing: 2 weeks – 1+ months
Curing really seems to make the effects of buds feel less ‘speedy’ and be better suited to medical applications like treating anxiety, reducing pain, and improving feelings of depression.

Additionally, curing gets rid of any ‘cut grass’ smell, harsh taste and other undesirable traits of some freshly dried buds. Over time with proper curing, those traits will be replaced by the ‘real’ smell and potency profile of your buds.

Two weeks is considered the minimum time to cure your buds, but I personally cure all my buds for a month or even a bit longer because the buds continue to improve for several more weeks.

So, after you’ve bought seeds and equipment, grown a plant from seed to harvest, trimmed, dried and cured your buds, that brings us back to the original answer…

The Cannabis Cultivation Timeline

Growing cannabis comes with a lot of uncertainties. That said, cannabis cultivation itself can be broken down into five distinct stages, regardless of which seeds you’ve selected.

GETTING STARTED

Before you just start throwing seeds into soil, consider what kind of grower you want to be. Are you running an indoor operation, or working in the great outdoors? Do you have the supplies fit for your growing environment? Have you made sure to pick seeds that’ll thrive where you’re planting them, indoors or out? Speaking on that last point, any aspiring grower should know the difference between photoperiod and autoflowering cannabis plants. There are a few key differences to note.

PHOTOPERIOD PLANTS

The main marker of a photoperiod plant is the potential for indefinite vegetation—as long as you keep the plants on an 18/6–24/0 light/dark cycle. We’ll talk more about that later, but it means these plants can withstand more mistakes in the growing process. It also means you can ensure your plant produces the best crop possible once you initiate flowering. All you need to do to make the switch is adjust the light cycle to 12/12. This becomes even more useful when you’re able to make unlimited clones of your optimised plant. The main drawback is that it’ll take around four months to get a substantial yield. However, you’ll have a larger and usually more potent plant once you’re there.

AUTOFLOWERING PLANTS

The way these differ from photoperiod plants is written in the name. Regardless of whether you feel the plant is ready, it’ll start flowering at a certain time depending on the strain’s genetic programming. In one sense, these plants are easier for novice growers because there’s less to think about in regards to light coverage and cycle adjustment. On the other hand, due to the limited vegetation time, you have fewer opportunities for mistakes. This isn’t ideal for first-timers, but the fact that it only takes two months from germination to harvest is definitely appealing. Autos tend to produce lower, milder yields than their photoperiod counterparts, but modern advances are bridging the gap.

5 STAGES OF CANNABIS CULTIVATION

Now that you’re familiar with the distinctions between photoperiod and autoflowering strains, we can begin to break down each stage involved in cannabis cultivation.

STAGE 1: GERMINATION — 1–7 DAYS

Even when your plant is a mere seed, the work you put in will dictate its success or failure. Germination is the stage when the first root cracks out of the seed’s shell, which takes between 1–7 days. The wet paper towel method is a classic approach here, but you start out with the major setback of tiny fibres all over your new root. You can plant directly in the soil, of course, but you need to ensure temperature and moisture are dialled in.

If you want to keep all your seeds safe and clean, we recommend the Royal Queen Seeds Starter Kit. With that, they can enjoy clean, undisturbed germination. Once they get to 2–3cm high, you can remove them from the starter and place them in a suitable growing container.

STAGE 2: SEEDLING — 2 WEEKS

Breaking through the germination stage, plants enter the seedling stage next. At this point, they’ll need about 18 or more hours of daily light. After two or so weeks of proper care, though, they’ll be well on their way to robust growth.

This is the point where it starts to look more like a cannabis plant. There will be one ridged blade per leaf at first, but the blades will get closer to their typical 5–7-finger stage by the end of this period. Until they get the full 5–7 blades, though, the plants are considered seedlings. Along with the increasing blade count, a vibrant green colour is another mark of a healthy plant. To keep them healthy, the two main things to keep an eye on are water and cleanliness. Seedlings are still fragile, so only light watering is necessary. Cleanliness is equally vital due to their disease and mould vulnerability. The perfect home for cannabis seedlings is a propagator, ideally with 70% RH and temps 20-25°C, under either white CFL lights or LED’s.

STAGE 3: VEGETATIVE PHASE — 2–8+ WEEKS

Vegetative growth is normally associated with a transplant at some point as plants outgrow the starter medium be it a Rockwool block or paper cup filled with soil or coco. Continued development of the root zone and robust branching are the top priorities for the grower. High RH of 50% is ideal and cooler temps 20-24°C can promote more females if growing regula r seeds.

Autoflower cultivators have even less time to play with than photoperiod growers as most autos will race into flowering after just 2-3 weeks of vegetative growth. It’s for this reason that many auto growers plant their autoflowering seeds directly into the final container. The clock is ticking with autos from the moment of germination.

Photoperiod strains can be kept in vegetative growth indefinitely so long as 18+ hours of light and suitable conditions prevail. This is what allows indoor growers to keep mother plants for years and why outdoor grower’s plant in springtime. Indoors or outdoors 18+ hours of light facilitates taking cuttings too.

This is the stage to pot up photoperiod plants into final containers, at least a couple weeks before switching to bloom or prior to Summer outdoors.

While the photoperiod strains can be kept in veg weeks or even months to allow for all kinds of pruning and training to boost yield like topping, FIM, LST or even a ScrOG the Auto grower is somewhat limited by time.

STAGE 4: FLOWERING — 6–12 WEEKS

At this stage, the focus of the grower and plants switches to the production of buds and the grower is already dreaming of a frosty marijuana harvest in the near future. RH needs to be reduced to 40-50% and temps kept between 20-28°C.

Cannabis plants will first give you an indication of their sex in the early phase of bloom. Typically within the first two weeks of flowering females will develop pistils or “hairs” to confirm their femininity.

If you see “nanners” or anything resembling a cluster of grapes protruding from flowers or anywhere on the stem then you have a male cannabis plant. Should you see both hairs and nanners then you have a hermie to remove right away.

Photoperiod strains are induced to bloom by the hours of light they receive; indoors the grower changes to a 12-12 light-dark cycle to artificially promote flower growth.

Outdoors Mother Nature dictates the grower’s schedule and flowering will only commence in Summer/Autumn as the hours of daylight naturally diminish, making for a longer more gradual flowering period. Weed growers in the Northern hemisphere don’t refer to October as “Croptober” for nothing.

Of course Autoflowering strains don’t follow the rules due to their Ruderalis genetics, so they will begin to bloom in about a month post-germination. Auto’s prefer to stay in 18+ hours of light for flowering and will be more productive on a light-dark cycle that would inhibit photoperiod strains from blooming at all.

Flowering generally lasts 7-10 weeks for indica and hybrid photoperiod cannabis strains, while the more Sativa dominant strains can take 10-14 weeks to fully ripen into primo head stash.

Autos really only flower for 30-45 days with a much more sudden transition into flowering, choosing feminised autos is a wise choice for novices that don’t want a seeded stash.

It’s always best to evaluate if a cannabis plant is ready to harvest by taking a closer look at those resin dripping buds. Using an inexpensive scope to zoom in on those resin heads to make sure they are milky and amber rather than clear removes all the guess work.

Once you confirm you’ve got a ripe marijuana crop on your hands it’s time to break out the trimming scissors and get harvesting. After two weeks slow drying in paper bags or hung up, at room temp and approximately 50% RH, you’ve got a stash.

STAGE 5: HARVEST, TRIMMING, DRYING AND CURING — 1–2 MONTHS

HARVESTING

Harvesting is the most rewarding part of the cultivation process for many growers. Watching your plants grow over several months is mesmerising, but finally harvesting the fruits of your labour truly is the peak of the experience. The flowering phase of the grow cycle typically lasts between 7–11 weeks, after which it’s time to strip your plants down of their buds. However, you don’t want to do this too early and prevent your flowers from fully maturing. Likewise, you don’t want to wait too long. Timing harvest is a crucial step, and there are multiple signs you should look out for to know when the time is right.

One of the best ways to truly tell if your flowers are ready for harvest is by getting up close and personal with a magnifying device. This visual advantage will enable you to detect minor changes that wouldn’t be noticeable to the naked eye. Some growers choose to use a jeweler’s loupe, which is essentially a pocket-sized magnifying glass encased in a piece of metal. Others choose to use devices such as digital microscopes, which provide greater detail.

Ultimately, the most important use for your magnifying glass is to detect the progress of your trichomes, and therefore, the proper time to harvest your buds. Trichomes are small mushroom-shaped glands that produce resin which contains the vast majority of cannabinoids and terpenes.

Looking for shifts in trichome appearance is the most accurate way to determine the stage of maturity of your crop. Trichomes are hard to miss and appear as a white frosty substance that covers the buds and sugar leaves. Zooming in on these structures will allow you to know how far along your plants are, and whether they are ready for the chop.

Earlier on in the flowering phase, trichomes will appear translucent, meaning they are still developing and should be left to mature. When approximately 60% of the trichomes develop a milky look, they are ready to harvest. It’s at this stage where they will produce the most significant high . However, some growers wait until up to 90% of trichomes move past this milky look and become amber, as this will cause the buds to develop a more stoning and sedating effect.

Another sign that your buds are maturing is when the pistils of the flowers change colour. Pistils are small-hair like structures that grow out of the calyxes, and are the reproductive organs of the female cannabis plant. They are the site where pollination occurs—if male pollen were allowed to land there. Pistils appear bright white during the early stage of the grow cycle, and eventually shift to an orange-brown colour.

Aside from the buds themselves, another way you can tell your plant is approaching harvest is by examining the colour of the leaves. Provided you haven’t overfed your plants during the final stage of flowering, a yellowing of the leaves will signal that your plant is reaching peak maturity, and that its nutrients are being fully utilised by the buds. By flushing out nutrient salt buildup with pH-balanced water for a couple weeks before harvest, a smoother, more pleasant smoke is guaranteed from each plant.

Now that you know when to start harvesting your buds, it’s time to learn how to trim them.

WET TRIMMING

You can trim your cannabis plants in one of two ways: wet or dry. Both have their own advantages, and each grower will differ in which one they prefer. Wet trimming refers to trimming off the sugar leaves surrounding the buds immediately after harvest while the plant still has a high water content and feels “wet”. This method is the most common, and arguably the easiest, as it doesn’t require a large room to dry out plants beforehand. However, wet trimming is literally sticky business. The resin from the flowers will cover both your hands and your scissors, but there is an upside to this. By scraping the resin from your scissors every now and then, you’ll quickly build up a supply of “scissor hash”, allowing you an early taste of your harvest.

DRY TRIMMING

Dry trimming takes place after your entire stash has been dried, and little water content remains within the buds and leaves. Trimming dry buds is definitely easier on your scissors since they won’t become as inundated by clumps of resin. However, accurately manicuring dry buds can be somewhat of a hassle too, making for a potentially less visually appealing final product. Moreover, dry trimming does require a fair bit of space. Growers usually hang entire branches of buds from a line of string within temperature-controlled rooms to let them air-out until sufficiently dry.

CURING YOUR BUDS

Now that harvesting and trimming are complete, it’s time to cure your flowers. Curing is an essential process that removes the last of the residual water from the buds, minimising the chance of mould and greatly prolonging shelf life. Curing also enhances the taste and quality of the smoke, making for a smooth and potent experience.

If you opted to use the dry trimming method, then your flowers will be ready to cure straight away. If you chose wet trimming, then your flowers will need to be properly dried before you go on to cure them.

  • To do this, spread them out over some cardboard, newspaper, or, even better, a wire drying rack. Whichever you choose, make sure they are spread out over a large surface area and exposed to as much fresh air as possible. Aim for a steady room temperature of 21°C and a relative humidity of 50% to ensure a longer but gentle drying process to maintain as much flavour as possible.
  • Now we can move on to curing. For this, you’ll need airtight glass jars to minimise mould from taking hold. Fill each jar so it’s ⅔ full, leaving adequate room for air. This is the perfect environment for excess sugars and chlorophyll to be broken down, a process which is key for those smoother hits of smoke.
  • For the first two weeks of curing, open each jar once or twice per day and remove each bud, checking for any signs of cobweb-like mould. If you detect anything, remove this bud from the jar and place it in the bin. Opening jars this regularly will also serve to replace the air within the jar, keeping it fresh.
  • After a few weeks, the need to check your buds as much will reduce; the drier they become, the less chance there is of mould striking. At this stage, you’ll only need to check around twice per week to expose your buds to fresh air. After a few weeks, your buds will be cured; however, some growers choose to go a few weeks further to develop pristine and high-quality flavour. You can smoke-test you buds as the weeks go by to see if the current taste suits your preference.

How Much Time Is Needed To Grow Cannabis Indoors?

If you ask most growers how long it takes to grow weed, chances are you won’t get a straight answer. This is because the time it takes to grow weed can depend on many factors such as strain genetics, growing methods used, and certain environmental factors. All things considered, it could take anywhere from 8 weeks to 7 months until you can actually smoke your harvest. Below, we offer some guidelines on the timescales involved when growing weed, so you can plan your grow accordingly and reap the final rewards!

THE GROWING STAGES OF CANNABIS

In this guide, we will look at the different stages involved with growing feminized photoperiod cannabis indoors. As we want to give you an idea of what to expect from the moment you decide to start growing to when you can finally enjoy your self-grown stash, we are also including preparation time and drying and curing time for your weed post-harvest. The following are the stages of a typical cannabis indoor grow:

• Preparation time before you grow (0–4 weeks) – The time you need to get your seeds and supplies together, and to get your grow room ready.

• Time to grow cannabis (8 weeks–7+ months) – The time needed to grow weed from the moment you germinate your seeds until harvest; includes the four growing phases of cannabis:

1. Germination (1–7 days) – When your seeds “come to life” and begin sprouting.

2. Seedling stage (10–15 days) – The “baby-phase” of your freshly sprouted cannabis plant.

3. Vegetative stage (2–8+ weeks) – The vegetative stage could last indefinitely if we’re talking photoperiod (non-autoflowering) strains. Most growers let their plants vegetate for a month or two, or until their plant has a reached a certain size. Bigger plants can mean bigger yields, but how long you veg depends on available growing space.

4. Flowering stage (5–16+ weeks) – This is the reproductive stage of cannabis when it begins producing buds. How long your cannabis needs to ripen its flowers greatly depends on the strain you are growing. Fast-flowering indicas can be ready after about 55–60 days of flowering, whereas some sativas could take a few months for their buds to ripen.

• Time after harvest (2–4+ weeks) – After you’ve harvested your plants, you still need to dry and cure your buds before you can enjoy them.

A DETAILED TIMELINE ON CANNABIS GROWTH

Now that you have an idea of how long it will take to grow weed indoors, we can start to break down some of the specifics so you can get the most out of your operation.

PREPARATION TIME BEFORE YOU GROW

You may already be set with some seeds and your grow room is ready to go. Great! In this case, there won’t be much prep time needed to start your grow. Otherwise, this period takes into consideration how long it will take to order and receive your seeds, as well as source any equipment such as potting containers and soil. This period will therefore vary depending on what you need, where you are buying from, the speed of your mail, etc. Expect the preparation time to take anywhere from 0–4 weeks if you still need some equipment before you can get started.

TIME TO GROW CANNABIS

Time: 8 weeks–7+ months

This covers the entire cannabis life cycle from germination all the way through to harvest.

• Germinating your seeds
Time: 1–7 days

Germinating your seeds is the first “serious” step when growing weed. If something goes wrong with germinating, such as low-quality or old seeds that won’t “pop”, there won’t be much to grow after all. But you needn’t worry if you get your seeds from RQS, as our cannabis seeds are among the best-quality specimens on the market with the best germination rates.

To germinate your seeds, you can use the Royal Queen Seeds Starters Kit Feminized for optimal results. Growers also germinate using the “paper towel method”, or they put seeds in a glass of water and wait for them to sprout. Alternatively, you can just place your seeds directly in soil in a seedling pot, or even germinate them right in their final container. With good seeds, it won’t take more than 2 days until the taproot of your seeds will show, although some sativa seeds can take longer to sprout, up to 4–7 days. The time required for germinating seeds can also depend on other factors, such as temperature. It is unlikely, however, for seeds to take longer than 7 days to pop.

• Seedling stage
Time: 10–15 days

Once you’ve planted your freshly sprouted seeds with the first set of embryonic leaves (cotyledons) popping out of the shell, this is when the seedling stage of cannabis begins. These baby plants are only a few centimetres tall and have just one or two sets of tiny leaves. It will still take some days until your seedling will start to look like an actual cannabis plant with the typical serrated leaves. The seedling stage will normally last 10–15 days or until your young cannabis plant has grown 3–4 leaf nodes. Around this time, your plant will officially enter the vegetative growing stage.

• Vegetative stage
Time: 2–8+ weeks

Your cannabis plant’s vegetative growing stage starts at about the time when it has outgrown its seedling pot and is ready to be transplanted into a larger pot.

If you’re growing photoperiod cannabis under 18 hours of light and otherwise suitable conditions, there is nothing that will tell your plant when to enter flowering.

This means you could theoretically veg your photoperiod cannabis plant as long as you want. This is also what many growers do to keep their mother plants viable for a long time. But unless you’re growing mothers, you will normally want to veg your plants until they have reached a certain height, before initiating flowering by switching your timer to 12 hours of light and 12 hours of darkness.

How long you can keep your cannabis plant in the veg stage will primarily depend on how much space and energy (electricity) you have. Obviously, you want your plant to grow as big as possible so you can enjoy a big harvest, but you also don’t want it to get so tall that it outgrows your tent or grow space. Having an approximation of your plant’s final height is essential in this case, as some spindly sativas can easily double their height during the flowering stretch. The same goes for some modern hybrids and even indicas.

Moreover, the growing techniques you use will also determine the length of your veg; if you’re growing in a SOG, with many small cannabis plants grown together in close proximity, you will usually initiate flowering much earlier. With other training techniques like topping, plants need time to recover from such “high stress” treatment, and therefore veg is lengthened by a week or more.

On average, when growing indicas and hybrids in a typical indoor setting, the vegetative stage will last 4–6 weeks.

• Flowering stage
Time: 5–16+ weeks

Photoperiod cannabis strains enter the flowering stage depending on the hours of light they receive. The naturally shorter daylight hours in fall signal outdoor plants to start bloom. If growing indoors, you must initiate the flowering stage yourself by switching your lights to a 12-12 cycle.

Following a short pre-flowering stage where some plants stretch significantly in length, your plant will stop vegetative growth and put all its energy into producing what you planted it for in the first place: big, juicy, aromatic buds!

How long it takes for cannabis to mature its buds can vary greatly depending on genetics. Some indicas bred for speed can be ready after 5–7 weeks of bloom. However, the average flowering time for most indicas and hybrids is usually 7–10 weeks depending on the strain.

Certain sativas, such as Amnesia Haze, can take much longer to flower. These strains need 12 weeks or longer until you can finally harvest their buds.
