85 is a good temp! Especially for Co2 uptake mannnn! Other than what I smoke or "donate" to others is far below market value. I did the math on my last grow and I "made" about $50 a month after expenses so $50 extra to run the ac matters to me! My goal is to not pay for weed and certainly not to lose money in the growing process. I wouldn't feel right getting $40-60 an eighth when it really doesn't cost that much to grow.
Your right about the co2,,, I do plan on letting the temps rise some when I get the co2 levels up.
Well first off if your doing things on the no no your risk is worth allot. Not just risk of popo but dumb fuckheads trying to rob you,,, also in that case I only got one person who buys from me for now on. Its not rape by a long shot he gets a really good deal and I get to continue doing what I like doing. With the cost of risk hes also paying for high quality genetics that may not tend to yield as much as other strains, bulbs and electricity, fertilizer, and my time love and effort. This comes into play when Im doing all these little things that take the extra step in search of a higher yields without compromising quality. On top of all that my prices are way lower than anything else he could get his hands on. You should be able to run that ac lower if you need too!
Anywho thats just my thought on it.
