I have used QB's and currently run AutoCobs. The QB's were stunting my plants. So you cannot best the adjustability of the AutoCobs. You could not take a single amount of my AutoCobs in exchange for anything else on the market. The hidden gems are the 6500 K AutoCobs too.
I switched my entire grow over to AutoCobs after running them side by side with QB's and use to grow with HID's. I have 22 AutoCobs in my garden of that says anything. I have tested HID CMH COB of different brands and the QB's. The Auto Cons are the best lights I have had to date and each run my GPW goes up. My first ever grow with the AutoCobs my GPW was the highest ever and higher than any time using HID and CMH. Now mind you I am not saying you can't grow buds of high quality with any of these lights. I am saying that in my exp the AutoCobs are what work best and compared to HID my use of power (Watts) overall went down by about 50 % and my grows are better. Also I have never had terps and frost like this before. I also "believe" the Citizen Cons used have something different in their spectrum than Cree and part of the reason they perform better but I can't prove this. I have also made my own DIY Cobs in the past. Feel free to check my threads and ask any questions you'd like. Tough need to get feedback from as many sources as you can to make an informed decision but just be sure that feedback comes from people who have used any of the lights that interest you. There a lot of heresay on the internet and most of it is incorrect.
