now, to do organic, what's this i keep hearing about worm castings, "teas", putting molasses into the water and spraying it on the leaves, etc? do i need to do all that stuff?
i think that was everything you mentioned in your previous post.
are you certain these 2-gallon pots will be big enough? should i go with 5-gallon instead?
if this list is complete for a seed to harvest grow in my 36x26x72 grow tent please let me know, thanks!
