...outside that is. I have a screened-in patio on the back of my house. I have enough property that neighbors aren't a problem. The only problem is the heat (Southeast US). Even with my fans going full blast, my internal temps still hit 86 today. My setup consists of one of these: Utility Cabinet ...lined with reflective insulation and two of these: Server Rack Fans ...for ventilation. My light is an 84X-PRO LED from HydroGrow (amazing light BTW). With this setup, my girls stay about 3 degrees warmer than the ambient temperature. I was thinking about adding this... ClimateRight CR-2550 ...on my patio to help with the temps. Plus, it will come in handy when it starts to get colder. Has anybody here had any experience with any AC units like this one? Any thoughts on how well it might perform?
