I just got a 600watt MH about 3 weeks into veg and before I had 2x 150watt cfls..... but my Q. is that; I had my cfls running 24 but with the big watt difference, gets lil hot in my tent(81F). and the no need to really run 24. (So I switched to 20/4!!) So for the first night(last night) and the first time I had the lights off for 4hrs! So now im running veg at 20/4 now, will this do anything like strees the plant out, anything really bad like start flowering cause I really didn't want to do that this early!! PLEASE LEAVE A TIP!! VERY CONFUSED.... THX
absolutely nothing will happen. maybe a slight slow in growth but even that should be counteracted by the mass increase in lumens. you're good. like you said just maintain those temps.
