TrolMaster Legacy BETA-4 Digital Day/Night Temperature Controller Reviews
Great unit
I love this thing
Review by Zoodleron 2/20/2020
Could be better
So the price wasn't too bad, but I do have some issues. First, it should really have an outlet for both heating and cooling, I want to grow year round and some months are going to need me to switch back and fourth all the time. Second, the unit has to be under the light in order to utilize the night/day modes (which was the main point for buying this particular controller), but in my grow area, I can't read the display or status lights because it is too bright. I solved this by mounting it in a dark area and then positioning a fiber optic cable to shine light from the grow area into the light sensor. It would be nice if the light sensor was on the probe. Otherwise, it does its job pretty well. If those things I mentioned don't bother you, you'll love this thing.
