Here is Mexico, electricity is very expensive and rare where I live in the mountains. But I think a small AC is definitely needed from my summer grows. However, tell me more about the Koolatron.
Have you ever dried in desert heat? It's very hard. I have a humidifier, grow tent, and a good exhaust. However, I also have a heat wave and no humidity.
I'm at day 3 of drying. Humidifier is running 24 hours a day to keep the humidity at 50%. I've got my temperature down to 82 f with a bucket...
