GT Variable Fan speed controller
A budget fan speed controller perfect for controlling the air exchange in a grow room. Using an extractor fan with a fan speed controller will give the grower more flexibility over the grow room environment. Simply increase or reduce the extraction rate to raise or lower humidity or temperature.
Humidity should be between 60-70% for vegetative growth (18-24 hours of uninterrupted light) but needs to be lowered during the flowering stage (12 hours of uninterrupted dark) to 40-60%. Using a larger extractor fan with a fan speed controller is an excellent way of achieving these optimal ranges.
Other benefits include less noise from fans and a longer running life.
