When your grow room is in a cold attic, garage or basement, night temperatures can drop too far for healthy growth. A heater helps you keep the climate stable, especially during the dark period. This collection includes Dutch Masters electric heaters of 2 kW and 3 kW. Choose the output based on the size of the room and how cold it gets; a thermostat or climate controller lets the heater switch on only when needed. Always place a heater safely, away from tent fabric, cables and water, and never cover it. Combine it with a climate controller and a thermo-hygrometer, and read about the ideal grow room climate.
