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

Let me know how that light difference works for ya. I was thinkin about doing the same thing...Thanks

yeah neat idea..subscribage, keep me posted on that 1 too.

i concur. late

I have a similar setup as far as using both lights. (1) 1000w HPS and (1) 150w MH. This is only my 2nd grow and my first was with the the 150w MH so I don't have a good base to compare the difference to. The first grow was a disaster with just the 150w MH. The plant was in the flowering stage for about 11 weeks and the trichomes were still not amber most were foggy and some were still clear. I had to harvest anyway because I was having guests and need to make sure no smell was present. I cured the buds and the potency was mediocre at best. This time around I got a 1000w HPS and the difference already is amazing. The buds are tighter and a whole lot bigger. Halfway through the flowering I decided to add the 150W MH. I just figured it couldn't hurt to have a little blue spectrum in there. Things so far are going great with both and I plan on keeping it for the next batch.
