    6 female plants is about max.....in flowering. And that is very, very cramped under one 400HPS light.

    6 inch pots for veg.
    10 inch pots for flower.

    Damn, Dude - Nice grow in those tiny cups!

    Wheatie: Coco is actually considered a hydroponic medium, so you use hydroponic values and techniques, which you can easily research in the hydro section.

    Right now I have a scrog going in coco with some of the plants in #3 pots and some in #5 pots and there isn't any noticeable difference in the growth. But with the coco, you water at least once per day and always flood the pots to the point of run off.

    Never argue with an idiot - they drag you down to their level then beat you with experience.

    All of this is just pretend. But if I grew marijuana, it would be in strict compliance with California Law, SB420.
