I never knew it had to be anything more or less than room temp. if success is any indicator then I get a 100% success rate

Bubble Cloner. 75/80F the warmer the cloning solution the quicker to root. You get up around 84F you get into problems with Oxygen depletion, slime, and root rot.
Growing Hydro 68-76F is what I go by. I try to keep like was said room temp @72F or so.
