Improvements after lessons learned from last year.

I started with a dutch bucket and NFT system that I was just going to throw in my back yard. I ended up finding a 10x20ft poly greenhouse for $150. Last year I buried the reservoirs, set up 2 55 gallon drums with float valves to fill up the reservoirs, and had a mostly successful season. My dutch buckets were too close to each other and 11 plants all became one gigantic wall of leaves. I remodeled the setup and wound up with what you see now.
