Ideal Co2, water temp, air temp and RH...

I've been reading as much as I can about ideal temps. The general consensus for RDWC systems is 68 F. I read that the ideal temp for plants to take advantage of Co2 is 85 F @ 1500 ppm. I downloaded a VPD calculator and the ideal RH at 85 F is 79%.

I understand there are issues with different fungi at these humidity levels but running HEPA filters should prevent that. I've also heard some growers do this but dial back the humidity the last few weeks of flowering. Anyone with experience I would love to hear from you - good or bad.

80% humidity is asking for, and getting problems. Hepa filters are not going to prevent mold. 40-50% is ideal to me.

Ideal canopy temp not room temp.

I run LEDs so room temp and canopy temp are pretty close.
