Atmospheric controls

Ok so I am in the process of revamping my grow setup. Currently I have built a armoire grow box with veg on bottom and flower on top. The grow area measures 2x2 with a 1x2 utility area for a total of 3x2. 4 strains will be run with either a 2 week or monthly harvest utilizing the scrog growing method. It will be all organic with a 250w hps for flower.

As the thread title implies, this will be a sealed box and I am wanting to know what options I have. I am in the process of researching small air conditioners, etc. These are hard to come by and can get VERY expensive...try $5000 for a thermolytic 2500 btu unit...I was thinking about using an icebox to cool the grow, but as it is sealed, this would create humidity issues. Does anyone have a reasonable solution (i want to keep my wattage down). I am also thinking about buying a mini fridge, taking it apart and then using the cooling unit in the box.

Also i need some help picking out the right co2 setup. It needs to be ppm controlled and will run off of a 20 lb tank. Does anyone have suggestions for a reasonably priced unit (or not so reasonably priced if push comes to shove)? Insights will be appreciated.

and just for fun, i'll be growing shnazzleberry #2, Vortex, jack the ripper, and agent orange.

Well i think i actually figured it out. The have mini dehumidifiers at walmart for like $50, pair that with an ice box and a Sentinel CHHC-4 and I think i'll be good to go...haha. Think the Sentinel is overkill?

Also, will an ozone generator will mess with the sentinel's co2 reading or hurt the buds?


Oh yeah, what is this 420 points thing? It has a "bank account" in my user cp...

So after doing some reading it looks like an ozone generator is out of the question for the size grow i will have. What about UV light as an odor control? I thought i remember reading about it on here and am Googleing it right now. Anyone have any experience?

Eh, I have given some thought to using a drink cooler to make a grow room. The free standing types you see in some stores. We used to turn them into flower cases after work back when I first started doing HVAC/R.
