Most decent aquarium heaters have an adjustable thermostat but you need to double check temps with a thermometer just to be sure as the thermostat can be off by a few degrees.
Some of the small ones are preset with no thermostat for higher than 70 which is too much, i still use them because they can. E cheaper bit hooked to a temp controller only cus I already have one, and I can hook multiple units to it in multiple dwc buckets and it has a display, and i know if the sensor in one bucket reads 65-68 the rest of them are about the same.
I prefer RDWC now as one good heater takes care of one system. I use the heaters for like 1/4 of the year and it doesnt even drop below 20F here, i cant imagine - digits. Id have to insulate the heck out of my grow trailer lol.
Res temps are critical, too warm and the oxygen from the air stones doesn't disolve as well and suffocates the plant , and you can start culturing nasty bacteria like pythium and get root rot that thrive in warm water.
To cold and growth will slow down if not stop all together.
More importantly though the sudden and extreme fluctuations in the water/room temps can stress/shock the plant.
Winter is a great time though IMO because a $20-30 25w heater in your case is way better than living some places where its hot all the time and having to run an expensive chiller all day.
Also you wanna make sure the roots dont touch it but Ive never really had a problem if they do.
I agree with lost, even a cheap $10 digital thermometer/humidity meter will keep track of your highs and lows, fairly accurately. Just as important.
The cool thing about the heaters is you can let the room temps drop if you want and really bring out the fall colors in you plants, without the roots getting too cold
Think of it like you have live fish in your tank, they need a stable environment or die in no time. Heating the whole house to do it can get very costly and uncofortable..
