Controls for the Greenhouse. 3 zone watering/misting, Johnson Controls A319 temperature control for cooling fans and vent control. Had a spare breaker box to use to store the 12v power supplies for the vent actuators which are hooked up to the 4 gang power box in the middle. Behind the solid white cover is a DPDT 12v relay which switches between open and close on the vent actuators which are controlled by the A319.
