Great product to implament microbes in your garden. Can be used during feeding, transplant and cloning. Helps keep ph steady roots vigorous and healthy.
Good light, grat for 3x3 flower or 4x4 veg. Just because light drops off drastically on the edges so in a 4x4 buds wont be as dense on the edges. I recommend 2 sp 3000s in a 4x4.
