Rion Roof Vent for Hobby 2, Grand 2 and Prestige Greenhouses

Add the Rion Roof Vent to your Rion greenhouse to improve air ventilation. Additional air vents reduce humidity and improve air circulation, which keeps greenhouses cool on warmer days. Add the Rion Automatic Roof Vent Opener, Item# 47315 (sold separately) for hands-free temperature regulation.
