I like to mix spectrums.In some grows I run 2 400 watt hps with a 4oo watt mh in between them to add blue to the grow. Im currently doing 1 setup that has a 1000qatt hps and a 1000 watt mh in the room set on timers so that the hps runsfor 6 straight hours then cuts off while the mh kicks on for 2 hours then it turns off and the hps kicksback on for the final 4 hours of 12/12.Wanted to see if the switching of spectrums for the few hours will help the total yield and compactness of the plants
