Controllers

Looking to find a few opinans on some controllers that have humidity control with a differental of at least 6%, and temp and co2 all built in or separate ones just looking for some reviews I'm looking to dial in my environment a little better thanx

These are all of the controllers I have used that have been very effective

(Not every controller linked has the same function.)

Had no problems with any of them each was used for at least 2 years and they all operate just fine.

Yeah, I recomend The Autopilot Greenhouse Master Controller also. I also have not had one problem with any autopilot devices, since they came out
You should be able to pick one up for around 450 bucks. Hell of a deal!
