RelayRunner is made to test products with many timing options. Its very easy to use, for product cycling, lawn watering, remote lighting, replace the watering system with a system that you can read. If your into hot house growing, time lights, pumps, vents, heaters, co2, system flush out. Have multiple fully repeatable schedules. This program has been in use in a few iterations (versions) for indoor growing and farming for almost 10 years. For product testing a few years. Remember the only constraint on power is the size of Solid State or mechanical relay, for extream power usage, such as a whole parking lot full of hps bulbs.
