I believe I over-fed this entire run by an extra 200% (was using 3 tbsp/gal), plants were fine the entire time. It doesn't get easier than this. Running this strazing again from clonse and will be using 1 tbsp / gal.
Build quality is OK, but the zipper stitching leaves a lot of tiny holes. I lost 2 plants to male flowers appearing, and I suspect it was from light leaking in; or bad luck with genetics.
Works great! Drivers get a little hot, but I was able to manage heat and humidity venting into the same 10x6 room with no external exhaust. I think this speaks to how little heat LEDs give off.
