Environment controller

I'm looking for the best budget priced controller to control temp and humidity any suggestions

Check out trolmaster Hydro X. You can add as you go. For example, if you decide to use it as a light controller and or add CO2 you can simply buy the sensors and adapters separately and add to the hydro x. There other options available as well and you can connect to the internet and monitor via app on your mobile also. If anything goes below or above the set parameters you will receive notifications on your phone.

Best budget for just temps and humidity is the inkbird ITC-608T
