If you encounter cold conditions in your grow room you will need to raise the temperatures to maintain the best level for your plants to thrive and these tubular greenhouse and grow room heaters will certainly do the job.
A common time for your temperatures to drop too low is when your grow lights turn off, greatly reducing the heat inside the room. Using a tubular heater to maintain the temperature when your lights are off can solve all of your cold problems.
These water proof heaters have two feet to mount them slightly off the floor, so all of the heat produced rises into your room and not into the floor and they are fitted with a moulded plug.
A 2ft heater can be used with a grow tent up to 1.2 square.
A 4ft heater can be used with a grow tent up to 2.4 square.
