QB boards and COBs in winter? Are they warm enough?

I agree, just got one of these, before the veg room would be in the 60's / 80's, Now it stays at 75 / 85. Right now it has 4 qb 120's & an 8 bulb t5, soon to be replaced with another 4 qb's. room is 36" x 120".

They are looking ok at the moment.
Obviously it's not optimum but they'll be moved into a warmer area in December.
I usually line the pots with polystyrene lining paper when it gets colder so the medium inside doesn't suck in the cold.
@ANC is right about running hydro in winter to keep the roots warm and the chill outta the room. Aquarium heater is great for that

Low temps are my biggest challenge. I grow in an unfinished basement, in Michigan. I've partitioned off the grow area (one cab and two tents, plus room to move around and for storage - the space is about 10'x15') with plastic drop-cloth, which I'm planning to double as we head into the colder months. Running a space heater in the garden, which helps, but it's having difficulty keeping up with the falling temps. I'm planning to (finally) run some ducting into the basement, but just into the grow area, so hopefully that'll get me through the winter.

Edit: I should clarify - low temps are my biggest challenge this time of the year. In the summer, HID just cooks my plants, which is why I made the move to LED. I figure it will ultimately be easier to keep temps up than it will to keep them down; especially with no way to add AC.

I'm adding some CMH to my LED's to help raise temps.
