Temp swings

That temp diff is fine but ideally a few extra degrees would help. Can you slow your extraction down?

I put my exhaust fan on a timer with the light So it stopped when light goes off

I would put your small heater on the timer not your exhaust. humidity will be a problem with the fan off

I rely on one of these to control the heater in my semi-insulated detached garage grow, it helps a because space heaters are unpredictable. Having steady temps will help you to find the optimal balance of light and warmth, and leverage that more consistently.

I'm not sure what kind of lights you are using (or how many watts), but in my space heat builds up over the course of the day. I found that if in the morning I brought the room up to a temperature where the tents were optimal, by late afternoon it was getting too hot, and by evening I was forced to use AC. I don't know the dynamics of your space, but I would suggest starting slowly with added heat, and watching it closely. Basements are way less weather affected than my old free standing garage, so you should be able to dial it in pretty easily, once you find the sweet spot in terms of how much supplemental heat to add, and when to add it.

That would allow him to drop the heater temp during lights on and raise it when lights are off, all while preventing a temperature over run. Very nice solution @Humanrob and cost effective as well.

Thanks, but even with that it can be tricky to maintain relatively steady temps. If without supplemental heat his lights are driving the temps from 66 to 77, then just bringing the night temps up to say 70, could bring the daytime temps up to 81. Alternately if his basement temps are reacting to his house heat system, then the lights might not be that much of an influence. Either way he has to factor in what's causing his current temp swing.

In my garage, it's not as easy as just programming minimal heat parameters. I have odd dynamics where it seems like the space hits tipping points -- it'll stay at a steady temp for most of the day and then slowly rise, and then by early evening hit that tipping point and start to build up unacceptable amounts of heat rather quickly. It's forced me to keep my grow cooler than optimal so that I have a buffer at the end of the day and I don't overheat. I hate using the AC in November, at least if we have a normal December the outside cold will allow me more options. Hopefully @Lennut 's basement provides a more stable platform and he can find his supplemental needs and stick to a steady program.
