keep in mind that the MH puts out much more UV than an HPS (if i'm not mistaken), so it's not so much color temp as it is wavelength.

case in point, a swiss grower planted two crops outdoors, one at 4500' and one at 9000' elevation. the crop at 4500' had about 25% more weight, but less trichs than the crop at 9000'. same thing has been known to happen in indoor grow rooms for those who bloom under a MH as opposed to an HPS. so i think you'd be best suited to throw them under the MH for the last two weeks of flower.

did that make any sense? sorry made some hash earlier!

headshake Reviewed by headshake on . UVb-UVa I did the best I could to try to understand the threads regarding the topic, but could not assimilate via the written word. Stopped in my local horti- shop yesterday and asked. Interesting theorys. I was/am considering adding another light fixture to my flower room. Would using a MH in one end of the flower area and moving the plants that are closest to finishing under that light improve my yield and trichome content? Currently the flower area is a 1000 W HPS. If you did this what Rating: 5
