I'd have posted, " PROVE your remarks"! Every imatation expert has a "buddy" who 1. grew the biggest damn plant of the planet, 2. Grew the worst, piece of shit plant ever. 3 read 1/2 a page of LED science and became an expert.............and will answer all questions with: " all you noobs are are stupid because I know it all......
I've grown 11 plants, in a 4'x4' space with a pair of Mars Hydro 300 watt "Old Style" lights, and grew some mighty fine plants. Would a high end light work better? maybe....... but that doesn't make these a bad buy, it makes a market for people who want a good growlight that doesn't cost hundreds of dollars. On fact, ( I wish I had bookmarked it ) I read a scientific study of several currently available LED growlights, and guess what? Some of the so called " good light, were not only not much better, some were much worse! California Loght works Solar Flare ranked second to last to Grow Star, a Chinese made piece if junk....lol!
