Thermostat & Humidistat Controllers

Let these handy little things do all the work for you.
You can automate as much as you like or as little as you want.
The easiest to start with is to automate your fans. It's nice to have the fans kick on before it gets really hot. We carry thermostats that you can just plug your fans into.

Try our Farmtek hi/low thermometer to get an idea of your highest and lowest temperatures of the day.
Sometimes you may not realize how hot it is actually getting in your greenhouse.
