That split system AC sounds cool, but it’s more than I can spend on growing. Great solution though.
While we’re not in the true coldest temps yet, I tested OldFogey’s idea last night when temps dropped to 68. I set the oil-filled radiant heater to turn on when temperatures fell below 72. I placed the heater in front of the intake port, and I run my fan at a speed of 1-2 at night so it’s always drawing in fresh air. It works…..but it’s probably inefficient kicking that space heater on and off. I didn’t test it for long, and I just didn’t feel safe leaving the space heater unattended.

After more research though I’ve decided to experiment with using a large heat mat as my heat source. It’s a constant 80-87 degree temperature, so nothing too hot. It will turn on if temperatures drop below 72 degrees. I am in a 2x4 tent and I found a mat that is 20”x 48”. My plants sit in saucers and I use plant elevators that raise them about 2 inches, so I don’t expect to cook the roots with the heat mat since there is airflow under the rootball. I also have a small fan on the floor moving air around 24/7, so the heat should be dispersed quickly. If this works, I’ll update for anyone else looking for safe heating solutions.
I could also lift the saucers off the ground with lifts if there’s concern about the roots becoming too hot.

Thanks again for the great ideas….
