In the beginning I wasn't really feeling it. But as the grow went on and was able to figure out the spectrum adjustments I think I finished ok with it and might run it again for another grow just to see. I do like the simplicity of the autocobs as they were just plug-n-play but I think I need to add 1 or 2 more autocobs to my tent as the jungle can get fierce. I would love to test out the quantum boards to see what the difference would be. What can I say but I'm addicted to growing and testing out new things to try and improve on.@bushmasterar15 So how do you like the light? You going to keep running it or go back to the autocobs?
