Does anyone have ideas on how I could lower the temp in an indoor growing area, beyond using AC? This doesn't apply to peppers, but I have a few sundews that are indigenous to the S. African highlands / mountainous regions. They don't mind temps in the high 70's to mid 80's during the day, which is perfect under my HID lamp, but they need a drop off to 60-65 degrees at night when the light is off in order to do well. Running the AC at those temps throughout the entire house would cost a fortune, and it's simply not an option. I'm looking for a non-expensive alternative. Any novel techniques / suggestions are welcome and appreciated.
