Built for the environment most growers overlook.
Reduces stagnant air in the lower canopy
Stabilizes under-canopy VPD
Improves CO2 movement through the stand
No room redesign or new duct runs
“We stopped chasing humidity spikes in the lower canopy. Two rooms in, the GentleFlow manifolds hold VPD steady through lights-out — and we never touched our existing ductwork.”
Elevate Your Grow with Under-Canopy Solutions
Underlight Labs designs equipment that solves real problems under the canopy, where airflow stalls, light diffuses, and yield potential is often lost. Our two flagship systems, the Alpha Stand and the GentleFlow™ Air System, work independently or together to strengthen the most overlooked part of your grow.
