Anywhere in the 70's is ideal, but you can get up to 85 and still do all right. you want to try to get some female clones if the temps are extremly high, because when groing from seeds the high temps can promote hermy traits or just all out mail plants. Femails are produced under the most ideal conditions you can creat. Some say that using Super Thrive can help in the development of females as well, I am using it right now for other added benifitts along with the hope that I get more females..
