ya...just read that thread its great,humidity is about 50% in room and rez temps are too high about 80,however i keep tons of airstones in rez and the water is boiling with oxygen,but still may be a concern....as far as the co2 boost here is a link.this shit works ...highly recommended,its direct co2 to the plant.its the cats ass as far as im concerned. the co2 airline in covering my 3x6 ebb and flow tub,i blocked the end of the hose and drilled small hole the entire lenght to evenly spread the gas,i use a timer to come on when lights are on...of course on large grows this wouldnt be practical but its working great for 20 plants..CO2 Boost - All-natural CO2 Generators for the purpose of CO2 enrichment and air fertilzation
