I'm looking to add 2 Kessel led's to supplement my 1200w hps flower room. Which color do I need to complete the spectrum with my hortilux 600 hps's? Blue, red, purple, or magenta?
Wow, hot topic. I read that the red is a bloom booster, but has no blue in it. The magenta has more red than blue, but has both. So I think magenta would be best with hps. Anyone??
This thread should be stickied! After reading more reviews on other sites. It looks like they recommend the red for supplementing hps. I still think the add blue of the magenta would be beneficial as well. Wish someone else had some thoughts.
