The Quest F9 is a low-profile industrial air mover that easily fits into your garden where space is coveted. Quest concluded that grow tables are trapping CO2 underneath the plants, because it’s heavier than air. This makes it more difficult for your plants to absorb CO2 needed for plant growth. In addition, the F9 has no lights for maximum darkness of your garden. The F9 may also be daisy chained together with up to 6 total fans on a single 15 Amp circuit. The F9 circulates 925 cu ft of air per minute at 1.9 Amps, onboard circuit breaker with GFCI protection and 20 ft 110 V power cord.
