Q&A with Jorge
Seeds, Soil and Lumens
I started to germinate seeds between wet paper towels. I put them on a plate covered plastic wrap and put the plate in a desk drawer. Then I started doing research online about growing this wonderful plant. I planted the first couple of seeds when one-inch-long white roots started to grow. I let the others continue to sprout and planted them as they showed white roots. I had forgotten about the rest of the seeds that were still germinating. When I lifted the paper towels, there were three seeds that had roots about 3 inches long and they had tiny leaves starting to grow where the seed shell was. I immediately planted them with the little leaves sticking out. Are my plants going to survive?
Plant germinated marijuana seeds with a long rootlet in rockwool to avoid heaving. Otherwise the germinated seed will “heave” or literally climb out of the medium!

This grate works great for marijuana seed germination. Wrap seeds in a wet paper towel and set them on the grate. The water drains off and seeds germinate. Make sure to keep it moist 24 hours a day.
Germinating seeds is not the problem it is the preparation and grow room goods that are stifling growth. Planning is paramount for successful indoor gardens. Prepared growers have everything they need before starting to grow. Yes, you did wait too long to plant the seeds and leaving them to develop leaflets could stifle development. But, the biggest problems you have are the soil and lighting. The soil becomes crusty because it is full of clay. My guess is that you dug it up in the back yard rather than purchasing light fluffy potting soil. Backyard soil is most often poorly suited for indoor cultivation in pots because it has too much clay, is too acidic or alkaline and controlling moisture and fertilizers in it is very difficult. The crusty clay cap is formed when the clay washes to the surface. This is similar to the way a fine cap of the fine particles in concrete come to the surface when it is poured. This cap is as hard as a rock and very difficult for seedlings to penetrate. Furthermore, the soil is difficult to penetrate for roots and drainage is so poor that little air is held in the soil. Roots require oxygen in order to take in nutrients in the soil or those provided by fertilizers. Outdoor soils are also full of insect eggs, fungus spores, bacteria and moss. Using the soil invites all of these maladies to attack your wonderful plants.
Sprouted marijuana seedlings under a CFL lamp will continue to grow into big strong, bud-producing winners!
When marijuana seeds sprout poorly, it is best to throw them out.
Marijuana seeds that sink to the bottom of a glass of water should be moved to a moist paper towel within 24 hours to avoid waterlogging and rot.
Plant germinated marijuana seeds in a rockwool plug so that you can see the tip of the sprout.
