The Coreconduit: Garden Controller System does more than we need for human living conditions so let's see what it is doing so we can make some changes. The author of the Instructable drones on and on about healthy plants requiring attention and boredom until,

"...I've programmed into the Arduino a function I called, "TheDecider" that makes decisions based on maintaining optimum environmental conditions for growing plants. I added 2.4Ghz Wireless Radio Transceiver modules and a modular receiver system so that data is transmitted to within 1000 feet."



Nice! We should take a look at this, "TheDecider"

Another plus for this project is:

"With safety in mind, I chose not to use relays that expose AC currents. Instead, I chose to use Remote Controlled Wireless Outlets for controlling lights, pumps, fans, heaters, and humidifiers."
