15 feet but yielded poorly

[Ron]

I lean more toward the engineering side of building systems than how to grow plants in them. If you only new how bad I abuse my plants by not controlling the ph or feeding them strait water because I don't have time to mix up some fertilizer.
I can't kill a plant if I wanted to and the only reason I can think of is I build good gardens.
I promise myself to do a better job this season of keeping the right mix.
