It’s getting pretty cool down in my basement and will only continue to do so as winter approaches. I now have 2 heaters in the tent. One is always on and has the thermostat set to 65 degrees. This will ensure the temperature never goes lower than that. The other heater only comes on when the light is on, and has the thermostat set to 75 degrees, so that it will never go below that when the light is on. This should keep everything in the recommended “daytime” and “nighttime” temperature ranges.
I also made a stand out of PVC and hung an oscillating fan from it, to blow on the leaves. There are also 2 clip fans in the upper part of the tent (not seen in the photo) to move air around.
