Well, For one with out the hydro set up they only take off $100, so I don't know what it is really worth. 2. I went to their sight and if you go you will notice that they have a message board. When I started reading the post I was thrown off. Several people, almost everyone said that the sheds run much hotter than advertised, right off the top when reading the fine print of the moderator on all of his posts replying to the heat problems he says that the units have to be kept at least a foot away from the wall with a house fan pushing hot air from the area for optamal, bad spell, results. Some of the posters stated that it was a poor build quality. And I found a couple posters that said the scrubber and Ozone gen didn't do anything to kill the smell. I am sure that there is more, but I can't remember right now.
One other thing, quite a few posters said that with heat issues that these units should not be placed in a closet, but I guess you could vent the closet, but that seems to defeat the purpose a little of spending all that money on a fully self contained system, if you have to add more to make it functional.
I have herd a few more good things about these www.homegrown-hydroponics.com/mistgrcaw17h.html
The only thing, they don't have a message board to hear about the real life use of these units.
Well good luck
