okay i cureently have 5 white widow seedlings with a 2ft 4 tube t-5 set-up over them 24hrs straight. i will have them like this for the next two weeks until i get a 600wattmh light for them. now while they are under the t-5 what should my temps and humidty level be? ord does it not really matter becasue the t-5's dont emit alot of heat? when i get the 600watt system i wll go on a schedule of 18/6 what will i need my temps/humidity to be then? what does it have to be during the dark period of the grow?
