I'm using a diy 1 gal. bubbler cloner, and having 100% success with it on day 8. But, what i was wondering is, what is the optimal temp you want the water to be. I have mine on low setting on a heating pad, and my temps are 85*. Altho i'm having success, is there a more optimal temp i should be shooting for? I was at around 76 without the pad.
