soaking marijuana seeds in shot glass

Keeping a temperature of between 75 to 85 degrees Fahrenheit is excellent for starting seeds. Warm, wet and dark is what they like.

Once the seedling has broken ground and I can see green leaves, I remove the cup from the humidity dome. Move your new baby to the nursery side of your garden with the 16-18 hour grow light cycle and circulating air.

Cannabis Seed Germination

Be careful not to over water* your seedlings. Wait for the top of the soil to get dry and crusty before you consider watering again.

You should now be on your way to some wonderful romance with your plants.

You can use your local water with one caution. Fill a pitcher with your water 24 hours before using it & leave it open. This allows chlorine and other potentially harmful chemicals to escape into the open air.

Remember! Most of the medical strains of marijuana we grow today (learn how to get seeds) have been bred over many years to produce plants that are easy to grow and which produce potent, medicinal buds. However, these strains have not been selected for the toughness of the seeds they produce since that isn’t important to us as growers. Just remember…

Rapid Rooters (Highly Recommended For All Setups)

Germination Method 2: Plant marijuana seeds directly in growing medium

Poke holes in the bottom of your cup so water can drain out easily!

New Rockwool cubes have a high pH – too high for healthy cannabis seed germination. Therefore it’s important to thoroughly rinse Rockwool cubes in pHed water, then let them soak in pHed water overnight before use. Since Rockwool holds onto a lot of water, after soaking they should be given a few days to dry out before planting seeds or making clones.

Rapid Rooters are nice, but not necessary. You can use them before you transfer your seedlings to their final container. The Rapid Rooter should be cut open lengthwise if you plan on using them for germinated seeds. I use big scissors.
