TL;Dr: Here is a list of some of the best grow tent fans found on the market and what makes them the best:

  • Top-rated fan for grow tents: iPower 6 Inch 442 CFM Inline Fan

A ventilation system is essential for your crops when you are growing them in grow tents. Since you are growing them indoors, and in a closed environment you need a fan to keep the carbon dioxide and oxygen in circulation.

In this article, I will review the best fan for grow tents and reason out exactly what makes them the ideal choice.

Before we get started, know that CFM stands for Cubic Feet per Minute. (airflow)
