Pre-Soaking in Water Germination Technique

A common germination method for cannabis is to soak the seed overnight in a glass of water that is at room temperature because this triggers hormones that signal the cells to start germinating.

Be sure not to leave the seeds in the water for more than 24 hours, as this will cause the seeds to become deprived of oxygen, drown and rot.

After you have allowed the seeds to soak, you will then remove the seeds from the glass of water and place them either in a:

  • Moist Paper Towel
  • Cheesecloth
  • Rapidrooter®
  • Light Soilless Mix
  • Any Other Growing Medium

You will then need to place the seeds in a location that is warm, about 70 – 90°F (21 – 32°C), and be sure to keep the towel or growing medium moist, not soggy wet.

If you over-soak the growing medium, be sure to drain off as much as possible to keep the seed from drowning. Within several days you will begin to see the sprout coming out of the seed if you are using a paper towel or cheesecloth.

If you are using another growing medium for germination, you will have to wait and see. When using the other growing mediums for germination, be sure not to dig, or open up the growing medium to ‘see’ if it is sprouting. If you do this, you run the risk of injuring the sprouting seed.

If there is fungus beginning to develop where the seeds are germinating, you may mist the medium with a very mild two-percent bleach or fungicide solution. Any more and you risk damaging or killing your seed.

Once the seed has developed its white sprout, you may now very carefully pick up the sprout and plant it. Be sure to have the growing medium that you plan to use to plant in, is prepared and ready to go, as the small rootlet is very sensitive to prolonged and intense air and light.

If you are planting the seedling into a soil mixture, cover the germinated seed with about 0.25 – 0.50 inches of fine soil or plant mixture with the white root tip pointing down.
