Full organic grow: Soil "Blackgold Natural and Organic potting soil". I have not been having much success with yield, so I stepped everything up a notch; bigger tent, 600 watt light. I also heard where storing your seeds in the refrigerator was good for germination. Somewhere between these changes I was unable to get a plant started, they shot straight-up and were weak and feeble - I pulled them. So obviously, the "shooting straight-up" was because the light was not close enough. I also took the unorthodox measure of planting the seedling about 1-1/4" deep - breaking the 1/2 inch rule. Once she broke ground, she still seemed a bit feeble, had a hard time holding her head-up. I began to suspect the new light. When I went back to Amazon to check the stats, from my orders - the 600W light was pulled and replaced by a 1000W light, so the manufacturing might be suspect (china). I put my tried and true 300W light back in place. This time I will use the draw strings to keep the light closer to the plant. I also stuck a bamboo stick beside her, propping-up that huge top leaf. I think it is also possible that the weak and feeble plants were caused by refrigerating the seeds, so I have fresh seeds on the way. But it seems as though she will make it. After taking the picture, I realized I could probably pull the bamboo - she is standing on her own. Go with God.
