this will be my first real indoor, I'm going with 50/50 biodynamic compost, ans coco coir...with earth juice as a foliar feed, in passive hydro...1 gal.square water jugs, cut off-16 per 1000watt. I'm gonna' rotate the stock every 12 hrs. on carts, to double production(I have no social life). 2 carts in the light, 2 in the dark, per light...2 lights- that's a 4X8' grow area...county codes say I can have 10X10'(100sq. ft.), but 2 lights should be plenty...especially with double production!
