Every Grandio Ascent comes with at least one roof vent, but larger greenhouses or those in hot climates often benefit from additional vents to maintain safe growing temperatures. Adding roof vents is one of the most effective passive ventilation upgrades available for the Ascent.\u003c\/p\u003e\n\n\u003ch3\u003eDoes This Kit Include an Automatic Vent Opener?\u003c\/h3\u003e\n\u003cp\u003eNo — automatic vent openers are sold separately. The kit provides the hardware to make the roof panel operable (manually). If you want the vent to open and close automatically based on temperature — without electricity or wiring — you can add a Grandio automatic vent opener to your order. This is especially useful for growers who can't be at the greenhouse every day.\u003c\/p\u003e\n\n\u003ch3\u003eIs This Kit Compatible with My Grandio Greenhouse?\u003c\/h3\u003e\n\u003cp\u003eThis roof vent kit is designed exclusively for the \u003cstrong\u003eGrandio Ascent\u003c\/strong\u003e greenhouse model.
