Looks good so far. Tent is in cold room also that doesn't get much heat so I run small space heater in tent. Because it's so dry in house with furnace running, I have to run small humidifier in tent to keep humidity above 35% as well. Drawback is that humidifier is ultrasonic and needs distilled water. I go through a gallon of distilled water in a couple days.
How are you watering? plant looks a bit to wet in the medium.
plants get a big droopy with excess watering a lot of time. May need to dry out a bit before you next watering.
Good Luck!
