yep, Eye Hortilux makes a bulb that does this in one envelope. A 600 Hps and 400mh all in one bulb that runs on a 1000w hps ballast. Covering more spectrum is seen as ideal.Is mixing a 400watt HPS and a 400watt MH together for the flowering period okay or should I go buy a second HPS? I just have 6 plants in there and I run the HPS the whole time then I just got a second ballast so I started up a MH i had extra.
Will the plants benefit from this?
