Absolutely. It's the way I was directed to do so in the beginning, and the way I do it to this day. I just use the bottom 3 inches of a Solo brand cup, and use another full solo cup to hide the seeds from light. I get very fast, and high % germination this way. Once the roots sprout, you place them in your medium of choice, keep that medium moist, and in a dark place. A heat mat can help increase their growth rate while they're so young and fragile. After the seeds have pushed their root downward, and have lifted the seed a few centimeters above the medium, I place a flourescent light 8 inches or so above them. Drop the light closer and closer as the plant ages, and get a fan on them on very low speed, as to not hurt the younguns, but to keep them shorter, bushier, and give their stems the strength they need to hold massive buds. Ok, just google the rest, I always carry on so much, sorry.
