Reply #2: When I used to grow (100% legal and licensed)..

[tridim]

I used a recycled organic drip system in coco fiber. Nutrients and water were pumped up from a reservoir below and dripped back down into the reservoir via gravity to be reused. Coco fiber is a byproduct of coconut production and is reusable for at least half a dozen grows. Coco is a gorgeous soil-less medium. I use it for house plants now.

The only non-green part of my grow was the light and ventilation. All things that could be avoided if cannabis was legal and I could grow outdoors.

BTW the article is wrong, Cannabis consumes CO2 and emits oxygen. I think I learned that in 1st grade. DERP.
