I can tell you from first hand experience that this is a good product. I have seen the Medium in use, and I personally own a Mini. I researched the hell out of this subject before buying. I was originally going to build my own, as I am on a budget. But, I was surprised to see all the high end features I was looking for, and at a price that didn't seem to out of line considering what the individual parts would cost if you purchased them all seperately.

I was just reading the description for the Super Jumbo!! Dang. That system looks sweet! I can't imangine how kick ass that would be w/ 40 plants under 2 1000w air cooled lights with co2! It looks like they thought of everything in that baby. It's clear that whoever designed that systems knows wassup!

I got my Mini about a month ago, and my ladies are thriving! It so easy to use. I literally plugged it in, added water + seeds, and sat back and watched. No kidding -- my ladies are growing about 1" a day, and look good!

If I could afford a Jumbo, I would definetely go for it. Looks super solid to me!! I say go for it...

P.S. Post pix of your grow!! Dieing to see this baby in use...
