Roof Vents will further increase the air circulation inside your Rion greenhouse. One roof vent per 4 feet in greenhouse length is recommended for the best possible ventilation. Each Roof Vent comes with a lever that can be manually adjusted as temperatures change. For added ease, try the Rion Automatic Roof Window Opener.
