Frequently Asked Questions

What size opening does this vent require?

The 16" intake shutter vent requires a 16.25" × 16.25" opening in your greenhouse wall panel.

No. It comes pre-wired with a 9-foot power cord and simply plugs into a standard outlet — no hardwiring required.

Where should I install the intake vent?

For best results, install it high in the lowest panel of the front wall, on the opposite side from your exhaust fan. This creates effective cross-ventilation and maximizes airflow through the greenhouse.

Can I use this without an exhaust fan?

The vent is motorized and designed to work in tandem with an exhaust fan system. It can be used independently, but pairing it with an exhaust fan and thermostat delivers the best automatic ventilation performance.
