Thermostatic protection and night/day rheostat

Discussion in 'Greenhouses' started by Lui Carlton, Feb 9, 2011.

  1. Being relatively new to this, I am building my greenhouse as good as I can. Can someone tell me the best/cheapest alternative to having a safety thermostat switch that will kill my ballast if the temp goes to high? This could save a crop in the case of something bad happening.
    Also, I am looking for a cost effective method for turning my hydro farm 6" fan speed down at night and up; in the day(when plants wake up). Thanks! Any ways to save the almighty dollar are highly appreciated!


  2. I use an electrician for all my wiring,relays and controllers for my lighting. I'm not an electrician so I don't want to lead you down the wrong path with thermostat/relay designs for turning off lights during a 911.

    Hydro Innovations makes an Icebox thermostat that has day/night settings.
