Grow tents trap heat and stagnant air around leaves, which slows growth and invites mold, and this 2-pack clip-on fan set keeps air moving through every stage from seedling to maturity. Each dual-motor fan delivers up to 125 CFM across nine fixed speeds plus an automatic circulation mode, running at 48 dB or quieter so it won't disturb a grow space near living areas. Placing one fan on each side of the tent balances airflow across the whole canopy instead of blowing hard from just one direction. Automatic 45 or 90-degree oscillation spreads air evenly over a wider area, simulating a natural breeze that helps strengthen stems, while the ABS housing clips onto most tent frames in a compact 8.1 x 7.9 x 9.3-inch footprint. Each unit weighs just 2.4 pounds and runs off a 12V power bank or DC adapter through the included Type-C cables.
