Running 2 450w vipraspectra LEDs in 4x4 tent how far should I keep lights away from canopy and should I run both veg and bloom switches
37 day veg no preflowers yet but light cycle just started like 3weeks ago been hearing a lot different methods looking for someone with experience for a Lil advice
I use the same light, 18"-24" for veg, 12"-18" for bloom, there's a basic test for leds put your hand under the light, if it's too hot for you it's too hot for the plants. Lower your hand little by little until the temp is good for you.
