[quote="Purplebloomcactus" ]I live in the Pacific Northwest where marijuana is legal. Growers are using this process for faster growing and bigger plants! All planting is done indoors without soil at first! The plants are bug free! Soil attract insects I think! Here is my experience with Citron (citrus Medica) this past year!

I used 2"mini- blocks from gro/dan (grodan101.com) product purpose inert medium for soil-less growing contents: Rockwool Mineral fibers has Ecolabel
If you go to website theirs a video for growing process!
