Fans and Blowers

Effective airflow is essential for healthy, high-yield grows. Fans and blowers bring fresh CO₂ into the canopy while removing hot, humid air to prevent mold or heat stress. Inline duct fans, axial, mixed-flow, or centrifugal, move large volumes (200–1000+ CFM), push air through carbon filters, and maintain stable temperature and humidity.

You'll find the best grow room fans here: inline models from 4″ to 14″ with quiet controllers and UL-rated components; durable wall-mount and pole-clip oscillating fans (like Monkey Fans) for canopy circulation; plus booster fans and blower units that resist humidity and support passive intake setups. These components keep your grow room snug, moving, and smell-controlled.

Frequently Asked Questions

What size exhaust fan do I need for my grow room?

Start by calculating your room’s volume (length × width × height) in cubic feet; aim to replace that air every 1–3 minutes. For example, an 8′×8′×8′ room (512 cu ft) requires a minimum of ~171 CFM (512 ÷ 3). Adjust upward by 10–40% to account for lights, filters, and duct bends, then add ~25% extra for safety. For most mid-size grow tents, this equates to a 6‑inch inline fan rated at 400–800 CFM.

How many CFM do I need for a grow room?

Ensure your fan moves at least as many CFM as your grow space’s volume per minute. Say you want full air exchanges every 1–3 minutes, your CFM = volume ÷ target minutes. After accounting for environmental factors like lights or filters, most grow rooms require anywhere from 200 to 800 CFM. Many growers pick a fan ~25–50% larger than the calculation to ensure efficiency and longevity.

What is the best fan set up for a grow tent?

The ideal setup combines:

  • A powerful inline exhaust fan matched to calculated CFM,
  • An intake fan (~20–30% smaller) or passive intake for negative pressure
  • Oscillating or clip fans inside to circulate air, strengthen stems, and eliminate hot spots.

For example, in a 4×4×7 tent, a 6‑inch inline exhaust (~400 CFM) paired with a smaller intake and a clip fan for canopy airflow creates stable temps and airflow.

Should I run my fan 24/7 in my grow tent?

Yes. Continuous airflow is essential throughout your grow to maintain temperature and humidity and prevent mold or pests. Exhaust and intake fans typically run 24/7, and airflow adjustments are handled via speed controls or smart controllers that adapt to environmental needs. Clip and oscillating fans also run continuously, often at low speeds, to mimic natural breeze and support plant health.

Should the fan be inside or outside the grow tent?

Inline and exhaust fans should be mounted outside the tent to avoid drawing heat from their motors and to simplify ducting/filter setup. Position the exhaust fan at the top to pull warm air out, and feed its intake duct through the tent wall. Clip and oscillating fans should be inside the tent, gently moving air across the canopy without directly blasting plants.
