I've only had experience with Quantum Boards by HLG and Viparspar and can't see myself going outside of these brands. Quality lights..

Thanks Frank Nitty for your response , I was thinking the a summer crop would yield at least 2lbs or more. but the plants only grew about 2.5 feet tall ,and they were not autoflowers .perhaps better lighting would increase the yield !
