The WaterMate 4-season controller is mains powered, and has the capacity to run LED grow lights, heaters or more pumps for extra watering.
In addition to the standard 12V "pump" output, there are 3 "Aux" outputs, which can power any 12V device up to 6 amps continuous.
Recommended connections
Aux 1 - heater
Aux 2 - heater
Aux 3 - grow lights
LED grow lights
Any of the Harvst LED grow lights can be fitted to the WaterMate 4-season outputs. Up to 8 lights on a single connector, using splitter cables. Fit grow lights to the bottom of a shelf above your seed trays, or fashion a frame or support depending on what you want to light.
We reccommend that the lights are no more than 50cm from the plants.
Heater cables
12v heater cables can be placed into soil to prevent it freezing, can be run underneath greenhouse staging to gently warm the aluminium, or can be in a small enclosed space (like our mini greenhouses!) to warm the air.
Heater cables are self regulating, the surface of the cable can get to 50C so be careful not to run them where your plants can touch them.
Heater pads
Up to 4 heater pads can be connected to a single output via splitter cables. Heater pads sit under a seed tray. They are currently unregulated and can heat a tray too much unless you have the temperature sensor in the soil of the tray itself.
Two of three outputs
The 200W power supply, connectors and circuitry is rated to a maximum of 14A continuous, so we have introduced control logic into the system such that only two of the aux outputs can be on at once. If you have lights (Aux 3) on, then only Aux 1 can come on. With lights off, Aux 1 and Aux 2 can both be on.
