Under 60F will slow growth, aim at 65-67F if possible.

I have a small 100w aquarium heater in my buckets. I use a Inkbird 308 controller to monitor and control the temps. I also use a Iceprobe chiller for each bucket, also controlled by the Inkbird. I hold at 68F pretty constant, only varying a degree at best. So far Ive had zero problems. I’m curious if I should lower them temps at night? Not sure if it makes a difference or not, but always looking for those extra grams and terps.
