I know and I'm waiting to see how you do, I hope all goes well if anyone can make me a believer would be you. That being said I think led lights perform great for tents, I've just yet to see anyone running de fixtures in a big room replace them and be happy with it. I have seen one or two 2 table grows with the Spyder and gavita LEDs that look close to being the same so I'm not saying it can't be done but I've yet to see a credible source do it on large scale in a traditional style grow.Well my tent run I pulled 15.5 zipz out of a 2x4 with 3 runts in an 8 plant run. I think if those runts had been bigger it would have been at least 3 zips more so. That impressed me so much with quality and yield that I decided to build 6 lights to replace my DE's in the daytime flowering room to help with heat. So we shall see but I used to think just like you on the LED.
