who grows in a sealed room anyway, you would need to run an air conditioner if your room was sealed (which creates more heat). and how would you control the humidity? mine stays constant at 40%, it doesnt go up to 80% and then trigger an exhaust fan. and my co2 stays constant at 1200 (from me breathing) it doesnt fluctuate around.

maybe i have bigger lungs than you i dunno.
I grow in a sealed room. I have no problems with controlling my temp/humidity AT ALL. Everyone has to try what works best for them. The fact that you're calling me a liar in half my posts, only proves your ignorance/inexperience on the subject.

Do you stay in your grow room all day long? If you don't, then how the heck could it stay at 1200 ppm constant? "Who grows in a sealed room anyway?" Well, who stays in their grow room all day, anyway?

I won't mention how I think you got those big ol lungs of yours. But I'm guessing it's not from smoking.
