Plant at least 12 seeds, knowing that 50% of them could turn out to be male plants, which you don’t want. You can also purchase feminized seeds, a bit more pricey than regular seeds, but then you will have female plants. Only female cannabis plants create the resinous flowers that we desire. Choose the most vigorous plants to keep and if you end up with more than 6 female plants, you can juice them or eat them in a salad for a burst of phyto-nutrition.
Avoid pouring water over the newly planted seed, since this can disturb its placement. You can carefully pour just 1 – 2 tablespoons of water over the top if desired. Place seeds under a good light source and keep them warm. After another 48 hours, a sprout should emerge!
It’s time to sprout your cannabis plants and get growing for summer!
Using a chopstick, make a hole 1/2 – 3/4 inch below the surface, using rubber gloves very carefully place the seed in the hole taproot pointing down. Cover the seed with dirt.
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.
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.
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.

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.
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.

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.
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.
