Environmental controllers, best buys?

Hi peeps, i was just looking for advice on what are some decent controllers to use in a sealed 10x10 tent. Ref' co2 supplimentation, air con and dehumidifier, controllers.
Cheers for any tips.

I have a controller. Kinda use it. But running a dehumidifier, A/C, CO2 controller of it pops my fuses. The dehui has a settings on it, So does A/C. Get a separate CO2 controller. I mostly use my controller as fan temp controller which can be done for cheaper.

Any master controller will work but you'll have to run relays for power
