Introduction to Best Oscillating Fan for Grow Tent

Having a grow tent and preparing to germinate some very good plants is one thing. Having the perfect oscillating fan to help in this process is another thin. Here is a review of the best oscillating fan for grow tent.

Some of the parameters that are controlled in a grow tent include airflow, light, temperature, and humidity to ensure the plants grow well. A good fan helps in controlling the airflow.

Most people are aware that there are two main types of fans; a fixed fan and an oscillating fan. A fixed fan remains in one position and faces one direction whereas an oscillating fan moves from side to side, up or down, or even both directions.

The movement makes oscillating fans more suitable for grow tents

Factors to Consider When Acquiring an Oscillating Fan for a Grow Tent

  • Fan size – The size of the oscillating fan-selected depends on the size of the grow tent. It is recommended to go for a fan whose size is the same or smaller than the tent’s vent diameter. If you are wondering what size oscillating fan for grow tent, a fan that is 4 inches in diameter usually supports a tent that measures 4 by 4 feet depending on how big the plants are and their number.
  • Fan speed – An ideal oscillating fan for a grow tent should have a variable speed that can be adjusted according to the season and the plants being grown.
  • Noise – Most grow tents are usually placed indoors and close to places we stay. It is thus very important to ensure the selected oscillating fan is not noisy.
  • Safety Certifications – Good oscillating fans are ETL certified in America under core safety standards for use in human environments.

Importance Of Using an Grow Tent Oscillating Fan

  • Controlling Temperature: An oscillating fan moves air in different directions around the plants and out of the grow tent. This movement of air results in a state of equilibrium and stabilization of temperatures between inside and outside of the grow tent thus controlling the temperatures. The movement of air also increases evaporation and evapotranspiration which cools the plants further.
  • Controlling Humidity: Humidity in a grow tent usually results from transpiration. Excessively high humidity usually hinders the growth of plants as it affects the transpiration rate. In combination with heat, it may result in the growth of mold and mildew. An inline fan is usually used to deal with humidity. However, an oscillating fan is very effective at circulating the dead stagnant air inside the grow tent.
  • Drawing in fresh air for the plants: Plants use a lot of carbon dioxide when growing and in the process release oxygen. A fan becomes necessary to move the oxygen from the enclosed grow tent to the surroundings and bring in ‘fresh air’ rich having more CO2 for the plants to use.

Best Oscillating Fans for Grow Tent Review

1. Hydrofarm HORF8 Active Air 7.5W Ultra Quiet Brushless, 8″ Clip on Fan

After many months of testing and analysis, this emerged as the best oscillating fan for grow tent. This fan has a suitable size (6 or 8 inches), quiet operation, powerful (7.5W), and very durable making it suitable for various types of grow tents.

It has a brushless motor and thus a very quiet operation. Brushless motors are also usually maintenance-free as no brushes need to be changed.

Hydrofarm 8 HORF8Fan has a very outstanding design with a clip that can be attached to poles or any sturdy edges inside a grow tent and start operation. The clip can be attached to any strong object ranging between 0.59 and 1 inch in diameter whether wooden, plastic, or metallic.  It is sturdy enough to support the fan for an extended period.

The clip feature also allows one to place the fan in different positions in a grow tent especially when testing different growth variations of the plants.

The Hydro farm 8 HORF8 Active Air Fan allows one to direct airflow in various directions using the shaking rod. It has a wide-angle of oscillation with up to 120 degrees vertically and 90 degrees horizontally.

This fan is large enough (6 or 8 inches) to cover most grow tents but recommended for grow tents measuring 6 by 6 or 8 by 8 feet respectively.

The only shortcoming noticed with this fan is the relatively short service wire and thus one might need an extension cable if the power supply is far from the grow tent.

Pros

  • Good build quality
