great ideas everyone, all i do is make sure the res's are in the shade, this keeps the temps in the right range, but even when the res is not in the shade the temp dont go up to high unless the res is nearly empty
its mainly just an amusing theory atm, but definatly has potential for res temps, for curing ppms droping/ph rising too fast and for curing too low a humidity problem.
amusingly, 1 adult and 3 minors in the ground floor of this house seem to increase the RH of the entire property from 20-30% to 40-50% just by breathing the air.
