Just an observation based on the setup... the heat mat right below a clay pot will increase evaporation through the walls of the pot. Clay pots are already prone to this effect (as opposed to plastic pots, which only evaporate through the top), but the warming effect will transfer water out of the soil faster. You can definitely use this to your advantage.
Try to figure out when the soil is going dry, and wait until that point to water well (until water comes out the bottom). I'm thinking with the heat and the lights you'll get relatively fast evaporation, so the watering interval could be every week or two.
The plant should not require a dormant period. I have grown other members of the family (not that species) and they tend to be more active at certain times of year (like summer), but that doesn't necessarily mean they actually go to sleep when they are not in active growth. Warm, bright, comfortable conditions (like what you have described) should keep the plant awake and content through the winter.
Be extra careful watering a plant like this after it has traveled through the mail and maybe experienced some winter cold or mechanical damage along the way. That's when it will be most vulnerable. Assume it is not going to be a heavy drinker until maybe late spring, and keep it on the dry side when it's not in active growth.
