Planting germinated cannabis seeds is the method least taxing to your nerves. Click to read about how to plant germinated weed seeds like a pro! Hi Nico, Quick question: Should I germinate my seeds before planting? If so, what's the best way to do it? Thanks, Cori W. Hi Cori, thank you for writing
Planting Germinated Cannabis Seeds The Right Way
Planting germinated cannabis seeds means making them crack and show the taproot between paper towels or in a similar setup, and then gently transferring them into the medium. Knowing your seeds are viable and alive gives you the peace of mind to patiently wait for the sprouts.
It’s possible to plant pot seeds the way nature intended: straight into the medium. However, planting germinated cannabis seeds is the method least taxing to your nerves and that gives you maximum control.
Planting Germinated Cannabis Seeds: Why And When?
For experienced growers, germinating marijuana seeds is something done almost on cruise control. However, first-timers may find this a nerve-wracking ordeal. They start to panic and make all kinds of mistakes. Nonetheless, germinating cannabis seeds before planting them has its benefits.
Why Germinate Seeds Before Planting Them?
Planting marijuana seeds after germination, not before it, is the least traumatic germination method not only for the grower, but also for the plant. When the seed is awakening, the conditions should be just right. Otherwise, you can run into problems:
- The medium can be made too moist, and this can lead to damping off and similar issues.
- After a couple of days, the soil begins to dry out, starting from the surface. If the seed hasn’t cracked by this time, it won’t crack at all due to the lack of moisture.
- If you plant the seed too deep, it can suffocate, especially if the soil is soaked with water.
- Some seeds take longer to sprout. Inexperienced growers lose their patience and begin to excavate, damaging the seed in the process.
Because of all this, it’s always safer to germinate your seeds first and then put them in the ground.
Best Soil For Growing Weed
When To Plant Germinated Marijuana Seeds
Suppose you’ve placed weed seeds between moist paper towels. The seeds may crack and show taproots after only 12 hours, but this usually takes longer – typically, a day or two.
You don’t have to rush and plant them as soon as you see that your seeds are alive and well. Provide a few extra hours for the taproot to become a bit longer – a half-inch (about 1cm) is okay, although more than an inch (2.5cm) is too much and should be avoided.

The whole process is actually very straightforward, quick, and seamless, but for your convenience, we’ve broken it down into separate steps.
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.
