I only do indoor so I can't really say on how that will work bringing it outdoor. But indoor when vegging the typical is 18 lights on/6 lights off or you can go 20/4 or 24/0(for veg, when you flower you got to 12/12). While indoor just dont let it get to 12/12I'm not really worried about heat do u know how much light they will need I don't want them to do a vegg bloom vegg when they are put outside
