hydroponic Nutrient Heaters

Click on image to enlarge

Thermostatically controlled heaters with adjustable temperature control knob. Ideal for ensuring that the roots of your plants are kept at the optimum temperature by preheating the hydroponic nutrient tank. The addition of a pump and airstone (to oxygenate the nutrient) will help to circulate the heat and keep the temperature constant. If your requirement is for more than 200 watts of heating we suggest you use two units, this will also give you some degree of protection in the event of failure. If you require different temperatures for your roots at night time use two heaters and two timers in the same tank set to different temperatures. Fully submersible units with fitted mains lead. Two sizes available.
