What's the deal on these. Anyone use them or have a price range on how much these will cost? Being in a basement when my lights are off it tends to get a little chilly when its -40 degrees with the wind chill outside lol. And we all know summer growing blows dick for heat and even more for humidity. If you can manage to grow without powder mildew in the summer where it gets humid as hell you will make it in this field (I doubt a lot of you even know what this is, what it looks like, or whether or not your plants even have it lol) so I am looking for one unit to control all of these. Does it exist? Obviously I am not going to spend thousands of dollars, at least not yet, for something commercial grade.
