Just checked my temps after having the pump in front of the AC and it went up 2°. My ice bottles aren't frozen yet either.

I used hydroguard a while back, but I thought it was just to eat algae? The reason the roots rot is because the water holds less oxygen, so IDK by what mechanism the Hydroguard would add more oxygen or make it so the water was able to hold more O2 at higher temps.

If I were to grow cannabis, I would only do so to supply myself and my close friends. Doing this would take myself and my friends out of harms way by knowing the source of our cannabis, as well as take hundreds of thousands of dollars off the black market annually. It would also lower the demand of black market cannabis, and would ultimately help keep cannabis out of the hands of minors.
