I was pretty skeptical as well. I didn't hear good things about the BC Northernlights units or the Quickgrow. I was ready to build my own. But a friend of mine surprised the hell out of me when he bought their Medium grow chamber. The build quality is super solid, and the specs on the unit are kick ass. So, I thought what the hell. I called in at like 3 am and spoke to a sales rep. He answered all my questions, and was no bullshit. I called back the next day and placed an order for their Mini grow box. To my surprise it was built by the following day, and shipped out the same day they received my payment! Less than a week from build to delivery, and I even got to customize my box w/ specific lights and grow sites. They even included free General Hydroponics nutrients! Overall their customer service is kick ass, and their units are solid! I know it would be cheaper to build on my own, but the final product wouldn't be half as good. Needless to say, 3 1/2 weeks and my ladies are luving it!!
