I have been doing some research and trying to make some choices for a small ebb and flow grow. I found a friend of mine in florida that has a bc northern lights bloombox, I think a 2005 model. He said that the only difference was the automated timers and the exhaust system. Retail back then was $2000 on this box. I was wondering if the box was worth $1000 and how much updating or upgrading I would have to do with a 5 year old box. I hear great things on the bc northern lights products and am considering going this route. Any help is greatly appreciated.
