The Art Of Germinating Cannabis Seeds
Often overlooked, it is all too easy to assume that the vegetative and flowering stages of cannabis growth are the most critical parts of the plant’s life cycle. However, with the chance of failure high unless you know what you’re doing, poor planning when it comes to germination can make or break your next grow. Giving your cannabis seeds the best possible start on their journey to bulging buds is a surefire way to encourage a healthy and robust plant.
Small, fragile, and in desperate need of a helping hand, there are several ways you can germinate your cannabis seeds. All methods have varying degrees of success, with both advantages and disadvantages. It is important to note that even with advanced growing expertise and top-of-the-line equipment, you may still end up with a few failed seeds. This is a natural part of dealing with a living organism. At Royal Queen Seeds, we provide a wide range of high-quality regular and feminized cannabis seeds. We label our genetics clearly, so you don’t have to worry about any unwanted surprises.
What To Look Out For In Cannabis Seeds
Regardless of where you get your seeds from, it is best to give them a slight (and delicate) inspection before planting. Most of the time, all seeds will germinate; however, poor-quality seeds will produce a weaker plant. Unfortunately, that is something you will not find out until well into the vegetative and flowering stages.
To avoid disappointment, seeds that have a darker colouration stand a better chance of germinating, while pale green or white seeds are likely to fail. Even if dark seeds look slightly damaged, they should be planted anyway. There is a good chance they will still germinate, even if the outer shell is somewhat crushed.
Germination Temperature Plays A Crucial Role
Before we jump straight into the germination methods, there are a couple of germination golden rules. For the best results, we recommend staying within these guidelines, no matter how you choose to germinate. That being said, of all the factors to consider, temperature is one of the most critical. Seeds will always seek out even the smallest amount of moisture, but they use temperature as a sign that they need to do so.
- The ideal temperature is between 22° and 25°C (71–77°F)
- Your growing environment should be damp/moist, but never wet
- Relative humidity range should be between 70% and 90%
- Seeds favour fluorescent lighting (Cool White code 33)
- Minimise the amount of seed handling you do
- In hydroponic/rockwool plugs, the ideal PH value is 5.8–6.2

What Is An Expected Germination Time?
Three fundamental principles will trigger that first small taproot to appear: warmth, moisture, and darkness. With the promise of moisture, a single root will take shape before slowly developing into the cannabis plant we know and love. In the right conditions, seeds will begin to develop within 12–36 hours of moisture being introduced to them.
Timescales can vary, as it all depends on how ideal your germination environment is (see the golden rules above). Even the worst grower could make a seed germinate, but it may take a few weeks and, of course, increases the risk of a weaker plant.
Choosing Your Germination Method
Glass Of Water Approach
Arguably one of the least effective methods, but it is still viable. Incredibly simple to facilitate, beginner growers may opt to germinate their seeds in a glass of water. Half-fill a glass or bowl with water that is approximately 22°C (71°F).
After 3–5 days, the seeds will start to open, and you should see tiny white tips appear. Once these roots reach 2–3mm in length, use extreme care to transfer them from the water to pre-prepared soil pots.
The soil pots will need small holes (roughly 10–15mm deep) for the newly germinated seeds to be placed into. Once the seeds are secure, you will want to place a fluorescent light 13–15cm (5–6 inches) away to encourage growth. Finally, don’t risk overwatering your seeds at this early stage. Use a plant mister to make sure they stay damp but not soaking wet.
Wet Kitchen Towel Method
Probably one of the most common methods of germination. The kitchen towel method comes in several iterations. Some growers use cotton wool pads or absorbent pieces of paper. For this guide, we will be using kitchen towel as it is readily available and holds moisture relatively well.
Place one sheet of damp kitchen towel on a flat surface. Space your seeds a few centimetres apart before placing the second piece of kitchen towel over the top. You need to ensure both pieces are damp, not wet. Once again, when the white root tips reach 2–3mm, move the seeds (carefully) to soil pots. Use the same guidance found above for planting techniques.
Planting Directly Into Soil
Planting directly into your growing medium prevents having to move seeds when they are at their most fragile. That first root tip is covered with microscopic filaments that are easily damaged. Given that both a cup full of water and moist paper towels are more prone to temperature fluctuations from their environment, planting in soil is a much safer option.
Start by filling pots with a premium-quality soil that has been soaked in water. Many growers also choose to lace the water with a root stimulator. Make a hole roughly 10–15mm deep. This will be your seed’s new home. Remove the seeds from their packet and place them into the pre-dug holes. Loosely cover the seeds, but be careful not to compress the soil above the seed too much. The root will struggle to penetrate solid soil, slowing plant growth. Lightly spray the top of where you placed the seed so that your growing medium stays moist.
If you don’t like the idea of pre-soaking your soil, you can use a spray to moisten the holes before you plant each seed. With enough moisture surrounding your seeds, you can still encourage a root to develop.
Your growing pots will need to be placed in a damp climate that is within the temperature range listed under our golden rules. After 4–10 days, you should see a young seedling sprout, while the roots will have begun to develop underneath the soil. The entire plant and its soil can now be transferred to a larger pot, where normal growing routines should start.
Using Stone Wool Blocks
Maintaining the ideal temperature (between 22–25°C/71–77°F) and moisture for germination is tricky. Leaving seeds out in the open environment or on a windowsill is far from ideal; a DIY climate-controlled cupboard would do a much better service. A warming mat is perfect for maintaining a constant temperature, but it doesn’t tackle the issue of moisture.
You will need to invest in a few pieces of unique equipment, but by using stone wool blocks, you can create a perfect utopia for germinating cannabis seeds. Soak the stone wool blocks in the same way you would a soil medium. The wool will retain the moisture and prevent the need to water during the early stages of germination. After the wool blocks are soaked, stick them in a plastic tray that also has a lid. Large cake tubs are ideal.
The dome of the plastic container will create your seeds’ own mini tropical climate. If you then place all the components in a temperature-controlled cupboard, you will have created a self-perpetuating supply of moisture—no need to touch the seeds again until they are ready to be transferred to your final growing medium as a young seedling. Using the stone wool block method, your seeds should germinate in one to two days.
Two or three weeks after germination, your young seedlings should be ready for their new home. At this point you have two options; transplanting them into soil pots, or taking on the challenge of hydroponics. You’ll know when the seedlings are ready to be moved because the root system should start to poke out of the bottom of the wool blocks. As long as the roots haven’t begun to engulf the bottom half of the wool block, they will seek out water and nutrients in their new surroundings and continue to grow downwards.
RQS Soil Plugs
RQS Soil Plugs are another great option when it comes to germinating seeds. They are easy to use and contain a carefully crafted formula of ingredients designed to help seedlings thrive. Composed of the highest-quality peat and coir, they provide a superb balance of aeration and water retention. This ensures seeds don’t dry out, while also preventing fungal diseases that cause the dreaded damping off.
RQS Soil Plugs contain key micronutrients that seedlings require for optimal growth and development. The addition of active biologicals also helps to establish the root microbiome with beneficial organisms that fend off pathogens and assist in nutrient uptake and organic matter breakdown. Furthermore, the pH-balanced nature of these plugs means cannabis roots can easily absorb nutrients without the risk of lockout.
They’re super easy to handle and take any hassle out of transplanting. Once roots begin to appear, you can transplant seedlings directly into soil or hydroponic systems.
To use RQS Soil Plugs, place a single seed of your choice into each plug. Place your plugs into a propagation tray and mist them with water—just enough to get them moist. Use a clear-plastic lid to maintain humidity, and aim for the temperature and humidity conditions discussed above. Use a small hygrometer to keep track of these important figures.
Propagators for growing cannabis seeds
No matter if you have a large cannabis growing operation or are an amateur just beginning your first seedlings, making use of propagators is a great way to control growing conditions and speed up your seed germination. A propagator allows you to take full control of your growing conditions, allowing you to germinate and grow your seeds and seedlings in a safe, moist and warm environment to give them an optimum chance of becoming healthy and high yielding plants.
Using a cannabis propagator
Any propagators can be used to grow cannabis, as they come standardised with a thermometer and built in LED Lights. They can either be powered by batteries or electricity, and allow you to control the environment within the container. Seedlings can sprout up to 30% faster when you use a propagator and the environment is much safer as you can fully control the heat and moisture content, and you cannabis seeds will also be less susceptible to damage by insects or disease. Seedlings can be kept in the propagators until they sprout their first set of leaves. This ensures that they will get a good start and grow into healthy, high yielding plants.
