yeah, usually people throw in some vermuculite too, but i cant get that around here.

Its hydro, like a soilless soil....

If i used real soil, like FFOF or something, it would be too expensive to change out every harvest. I do like 30 plants, so it would be pricey, this i can get for like 15 bucks for 30 pots and i get great results. I'm still learning, but ima bout to harvest some nice nuggs here in a few days.
