Benefits of Fans

Having proper grow tent ventilation is probably the most important factor in operating a grow tent, which is why you should consider using a grow tent fan. Without proper ventilation, your plants are likely to attract dust, pollen, or mold. Using a grow tent fan will provide circulation, therefore help eliminate mold, while providing the CO2 needed to grow in order to grow, which also helps reduce harmful pests and common plant diseases that will commonly occur in a poorly ventilated grow house.

Installing a grow tent fan also helps control humidity, remove excess heat, and produces faster growth. If you’re considering purchasing a grow tent fan, you should first research the fan carefully to ensure it meets your needs and capabilities.
