Why do you need a heater for your marijuana grow room?
Marijuana plants thrive in temperatures of 20 to 30 degree Celsius. This means that if the temperature goes down, then the marijuana is going to grow slowly resulting to low yields.
However, if the temperature is low for a long period, then the effects are going to be much worse than just low yields. It is for this reason that you need to have a grow room heater that is going to regulate the temperature of the cannabis grow room and ensure that the temperature in the grow room is conducive for the growth of the cannabis.
Besides the low yields, low temperatures can also result into the growth of mold on the cannabis thereby rendering the cannabis useless. The following are some of the best heaters for cannabis grow room

Majority of the heaters mentioned above are small in size making it easy for them to be placed inside the grow tent. However, in case the heater is too powerful , then you have to place it outside the grow tent. Also, be sure that the heater is too hot when you are placing it inside the grow tent.

Buying Guide: Choosing the right grow room heater
Below are some of the factors that you should look out for when shopping for a grow room heater:
To avoid any accidents in the grow room, you need to consider safety when using the heater. Some of the accidents caused by heaters include burns when the heater comes into contact with bare skin. The other accident is when the heater is a source of fire in the grow room especially when it overheats.
One way that most heater brands ensure safety is by equipping the heater with a sensor that automatically shuts off the heater when it overheats. Once the temperature lowers, the heater restarts. The other safety feature found in some heaters is the tip over protection. The tip over protection ensures that the heart stops working once it tips over.
Also, make sure that the heater has been tested by a recognized laboratory like ETL (Intertek). This will ensure that the heater’s construction and performance is safe for use since it has been checked and approved by the laboratory.
Whether you want the heater to be portable or not is up to you. However, since you are going to leave it in the grow room, the portability of the heater will not surpass the quality and safety of the heater since you are going to leave it in the same spot once you get the perfect spot in the grow room to place it.
