ok i wanted to implement some co2 into my grow. i have two separate 5x5 tents and growing with the ebb and grow system. also it is important to know that i am in an apartment..i know jack shit about co2....i know to kill the out take when the co2 is running...so i assume to only run it when the lights are off? should i kill my intake too? kill oscillators too? also could you recommend a cheap system that isn't based on some ridiculous shit like yeast and sugar. thank you for your help!!
