When i get my grow journal done...you'll see my random array of lights i have used. (going to post it in its entirety in about 50-60 days) at the moment i am using 2 x 10w (6000-6500k) and just added a 30w (6000-6500k) I also have some other normal household LEDS in the mix...Basically progressing and adding lights as my 2 females get bigger. (day 40 in veg) Im trying to illistrate the idea that you dont have to use these branded panels....that growers seem to be stuck on...maybe im wrong??? Mweh, give a whirl, no one else seems to be reporting about it. When i flick to flower....i have some 2700-3500k ready to chuck in. No more awful pink hues in my photos!
