I'd yes his efficiency may be better but he did not take into account my space is not much larger than his (10X5), I finish clone to harvest in 3 months, veg under t5 ho's for 3weeks, and my liquid cooled 1000watt hps runs on a track, and get 40 plants in one room. I get small plants with large, quality budds but good info on the peroxide, not going to use it yet but still don't know what dillution rate to use, ive heard 3%.
