ya i agree that the mh was a good idea ive never grow with mixed spectrum, would u say it increases yield or maybe trichome production
Yes I believe you get much tighter, fuller buds with MH supplemental, but I'm a big believer in adding UVB to the spectrum along with the added blue/white light that MH adds and Plasma does both. It is spendy though.
I read this paper a while back, I think it was in 2012 where a guy mapped out all the places in world historically known for their high THC content plants and then he overlaid a map pf places that had higher UV radiation in the atmosphere and wallah there you go perfect match. There are many that believe the "sunburn" the UVB radiation delivers to the plants increases THC content by 5%. Not sure about that percentage, I just know what's sticky and what I like to smoke. Too much UVB is a bad thing and will kill plants.
I agree with the comment about DE fixtures I have 4 Gavita 6/750DE's and 2 Gavita 270 LEP plasma on light movers in a 10 x 12 area, works well, had to buy some UV sunglasses though. And everytime I open the door to my grow shed I feel like I'm lighting up my small town.
