## Description

MARS HYDRO 6 Inch Inline Duct Fan with Temp Controller, Exhaust Fan for Grow Tents, Hydroponics

Review: Au top et silencieux
Review: Does the job but very noisy compared to rvk, the auto function does not allow for a minimum fan speed to get negative pressure on a tent some once it's cold the fan just stops. Also when it's hot the fan will never go above level 5 out of 10 to cool it down... I have an RVK that's 10 years old, with a basic fan controller you can forget about it and it's no more noisy than a quiet hum
