This would work fine. You could even run some duct work to help move the warmer air where you need! Cheers and happy growing!

When Should I Consider More CO2?
I flower my plants in a mylar lined box, roughly 2' deep by 4' wide by maybe 6' tall, using two 300W Mars Hydro LEDs. With that amount of light on the plants, would you recommend more light, or CO2 supplementation, and if so how much?

So I was wondering roughly how long would you typically germinate autos and if it would be okay I started them in 5 inch pots then at what point should I move them to 15L pots.

How to increase temperature?
What is the best way to increase heat in small grow space (2x2x4)? I'm running an LED light, maybe should have gone HPS but it is what it is. My area is in an outbuilding with poor insulation. Temps keep dropping below 70, I'm using an oil filled radiator placed next to the box
