Cool Tube Reflector 120mm x 490mm
The purpose of the Cool Tube is to remove hot air produced by high pressure sodium and metal halide bulbs more efficiently from your grow tent / room. This can be achieved by blowing cold air through the cool tube or extracting the hot air from the cool tube.
When used in conjunction with ducting and fans, this allows air to flow through the cool tube, thus helping to control the environment temperature.
The biggest advantage of the Cool Tube is that it can be mounted slightly lower, thus enabling the plants to receive more light, without being scorched by the heat.
