I just started with new White Widow seeds. With small fluorescent light.
i am growing in an extra bedroom. I have a MH 400w grow light.
I have made my super soil using worm castings/perlite/coco coir equal parts for 40 gallons.
I mixed in small amounts about 1 half cup each of
bat guana. Bone meal. Kelp meal. Blood meal. Seabird guano. Humid acide.alfalfa meal. Langbeinite. Charcoal powder, mycorrhizal and azomite.
