Just a hint, get some shipping pallets and raise the pots up off the ground if they aren't already. Contact with cold ground will make your plants act weird- you will see slowed water use, lockouts, and symptoms similar to overwatering.

I had to keep my mothers in a cold basement for a couple months last winter and set the heater so air circulated UNDER the pallets and kept the soil reasonably warm. The space was already set up and had previously hosted a grow, and the pallets were already there. Apparently the previous occupants had discovered that trick themselves!
