Seed Germination & Planting

Hi Cori, thank you for writing us! Your question is pretty simple to answer, but sometimes not so simple to do! In short, yes, most growers tend to germinate seeds before planting them into their grow medium of choice.

To be clear, however, germination of seeds is not necessary prior to planting in medium. You can sow seeds directly into the medium and they will also germinate there, but not always with the same success rate. The reason growers choose to germinate outside the grow medium is because it is easier to control the conditions surrounding the seeds. This leads to the second part of your question, which is the best-case practices for germinating seeds – this leads to the harder answers.

There are many different ways to germinate seeds. Probably the best methods involve keeping the practice as natural as possible. The simplest methods use water, warmth and darkness – all conditions the seed would naturally encounter underground. Many folks simply lay some seeds down on a paper towel on a flat plate, cover them with another paper towel, then moisten the paper and place the plate in a warm dark place. A popular hiding spot has always been on top of the refrigerator, while more professional growers employ heat mats that lie flat beneath seedling/ clone trays. Heat mats are an excellent and inexpensive aid for seed germination. Whatever you decide, the temperature should be 10-20 degrees above room temperature, or range between 78 – 90F.

Of course, there are always the tricky strains or the old seeds that are quite fussy and refuse to pop. These seeds require a bit more attention and creativity. Some people prefer to soak the seeds for a short period before placing them in a moist and warm place for germinating. Some people go as far as to use mild chemical solutions to help soften the shell and prod the seeds. Other growers will even use very sharp and sterile razors to carefully slice seed shells or tips to help induce germination. These practices are all risky and should only be used as a last resort.

Once a seed cracks open, the taproot appears. This taproot will become the plants primary root from which all other roots will grow. Technically, the seed is germinated once you can see the white of the taproot. Some grows prefer to wait until the taproot is 1-2 cm long before planting the germinated seed into a medium. Once you are ready to do so, be sure to place the seed about a half-inch below the surface of the medium with the taproot point downward and the seed shell on top. Be sure there is some space for the seed shell to push upwards through the medium, towards the light. At this point, the very young seedling still needs moisture, warmth and a bit of light now to direct its growth in the right direction. The seedling will likely be in this medium and container for a few more weeks before the seedling is ready to be transplanted into a larger container for vegetation.

Putting seeds in soil , root up , root down.

Ok, so I have had success putting them root down.. its what I have always done. Im no expert but ive grown a couple times with shitty grow rooms, and they have always come outta the ground. But, I was reading a post the other day that said to put it root UP, because the root curls , and it will only have to curl once to make its way down. So instead of having the root down , where it wastes energy curling twice, once towards to “top” of the seed casing, and then down again to the bottom of the pot. u put it root up so it only curls once, downward.

Im starting to think its true, because after looking closely at a germinating seed, it down infact look like its curling towards the “top” of the seed casing.

I soak my seeds in water and just throw them any way they land on the soil and cover them. It is good to put the root down.

thats what everyone says. And also what I believed. But after reading about it , and actually looking at a seed when the root is first coming out. It does look like the seed should be placed root up , as the root looks like its curling down like the post I looked at said.

Dunno , i never put em in exactly perfect anyway. Anything will work really.

I see what ya mean about the root curling. I just looked at my sprouts before coming to where i have internet service. When i go home im going to check that out. Mine always grow as well. Interesting thought.

I used to put them root down. Then read somewhere to put them root up and have been doing it that way since. I think it works better. Makes more sense to me anyway.

A CUT and PASTE for you all I have read ssen and heard of both up and down

Marijuana seeds should be placed with the POINTED END UP into a prepared cannabis seeds germination bed or just good soil at a depth of 1/2 to 3/4 inch. The embryo tap root emerges from the pointed (stylar) end and the natural method of growth is for this root to make a turn and grow downward (see the illustration) This bend formed by the downward curve of the taproot is what emerges from the soil and the friction of dragging the cannabis seeds upward helps the new plant to loosen and cast off the seed case when it breaks through the surface. If the cannabis seeds are placed with the pointed end down, the embryo will be required to expend a great deal of its stored energy for twisting and turning to position the tap root when it realizes that it is heading the wrong way (see illustration of germinating marijuana seeds) The seedling will need this energy to exert the forces required to later lift its head (now enclosed by the two halves of the seed case) above the soil, cast off the seed case and then spread its two embryo leaves and begin the life-giving photosynthetic process. This is a critical stage in growth and carelessness in placing the marijuana seeds will exhaust even the most hearty seedling and result in a slow start and a feeble plant in later life. Cannabis seeds should be placed in a small hole at a depth of 1/2 to 3/4 inch. An excellent medium for germination is a mixture of rich humus and fine sand, such as the type used for aquariums. The soil needs a ph of 7.5 to 8.0 and should not be so moist that it sticks to your fingers. If the medium is too moist, the seeds will rot and ferment before they can sprout. A simple test for moisture is to stick a pencil into the soil and if soil adheres to it when removed, then it is too moist. Sort of like when you test a cake by sticking a straw into it to see if it is baked through to the middle. The ideal is not too moist, and not too dry – and be sure that the soil is well-drained. Research has shown that a soil temperature that is at, or slightly above, the air temperature promotes the best survival rates and growth.

My question is in the wild when plants drop their seeds do the drop them point up or point down think about it
im not sure it really matters it has to work harder one way then the other but it would only seperate men for boys or should i say girls from woman

I’m new to growing and i purchased some seeds from a website. My plants are about 2 weeks now and they are about 8 inches tall with the four leaves. I think they are on pace, what sort of things should i do to improve growing at this point? I have them under a hp gro light 24 hours a day. Also what new stages should I be looking for to know their healthy?

Hopefully all of you aspiring growers have been able to get your seeds so we can move to the next step: germination.

Take great care handling seed and seedling. Most flower and vegetable seeds are simply planted directly in the soil, but because of the value of cannabis seeds, germinating seeds prior to planting is encouraged. Growers can achieve a much higher survival rate by germinating in a non-soil medium and then transferring the seed to soil once the tap root has emerged from the seed.

Here is one of the simplest and most successful methods: Put a double layer of paper towels on a dinner plate, then thoroughly soak the towels with water and tilt the plate to drain off the excess. Place your seeds on top of the wet towels and cover with another double layer of soaked paper towels. Be sure excess water is drained off—you don’t want the seeds to be swimming.

Cover the plate with an upside-down plate or pot lid. A plastic bag or plastic wrap also works. Don’t make the seal tight—you want to leave some openings to allow air flow.

Keep the germinating seeds away from direct light. For best results, keep them at about 75 degrees Fahrenheit. A radiant heat source, like a heating pad, helps expedite the process. If you’re using a heating pad, be sure to keep the heat setting on low and place a folded hand towel between the heating pad and plate: Direct contact between the plate and heat source can cook your seeds.

Under the right conditions, seeds usually open in one to five days, so check them daily. Do not allow the towels to dry, and add water as needed to maintain moisture. Some seeds can take as long as 10 days to germinate, but if seeds have not opened within 10 days, they are not viable.

When the seeds open, the first thing to emerge is the root. Once the root sprouts it can grow quite fast.

When the root grows to a few millimeters in length, the seed is ready to be transferred to soil. Always take great care not to damage the tap root when handling. The best soil to use for a sprouting baby ganja plant is a “seed starter” or “seedling” mix. These are light neutral blends with very little fertilizer. Heavily fertilized soils will kill seedlings quickly, and cannabis seedlings prefer loose, aerated soil that their roots can easily penetrate. A bag of good starter soil is easily identifiable: When you pick it up, it should feel light and fluffy. Soils that are heavy and compact are not good for seedlings.

Now, on to potting (no pun intended). A healthy seedling will be ready for transplanting into larger container, with richer soil, in about a month. A 16- to 20-ounce container is ideal for a seedling’s first home (many growers use a Solo cup). The container must drain, so punch some holes if needed.

Fill your container with pre-moistened soil and create a hole about a half-inch deep for your seed. The tip of a pencil works well for making the right sized hole. The seed should be about a quarter-inch below the surface.

Place your germinated seed, root down, into the hole and cover lightly. Do not pack the soil on top of the seed; a light protective layer of soil is all that is needed.

Once they sprout in one to three days, new seedlings will need lots of light, and fluorescent grow light works best. Give your baby ganja plants 16 hours of light per day.

It’s very important to have a breeze on your plants immediately. A fan placed at the proper distance and speed should create a breeze just strong enough so your plant “dances,” but not so strong that it’s bent in one direction.

Without a breeze, indoor ganja plants won’t receive the stimulus needed to develop sturdy stems and branches, which the plant will need to bear the weight of big, sugary buds.
