Our Accessories

Each accessory is made for a specific range. Extension kits, additional doors, roof vents and the automatic door and window opener are built for the five polycarbonate models, and you select your model at checkout. Roof windows, additional sliding doors, the gutter system, curtains, window openers and the decorative roof ridge are built for the aluminum and glass range. Raised beds, shelving, irrigation, shade cloth, water tanks and garden tools work in any greenhouse.

Yes, if it is a polycarbonate model. The 6.6 ft extension kit adds a full section and can be repeated up to about 98 ft of total length. Order the same panel thickness as your greenhouse, 4 mm (5/32 in.) or 6 mm (1/4 in.), and select your model so the profiles match. The glass and wood models are fixed structures and cannot be extended.

It uses a sealed wax cylinder that expands as the air warms and contracts as it cools, pushing the vent open and pulling it shut on its own. No wiring, no batteries, nothing to plug in. It typically starts opening around 68 to 77 degrees Fahrenheit and is fully open by roughly 86 degrees, which keeps the greenhouse from overheating while you are away.

Roof vents, gutter components where applicable, the anchoring base kit, all seals and fasteners and an illustrated assembly manual come with every greenhouse, not sold as add-ons. The items on this page are upgrades and additions, not missing parts.

No. Common household tools are enough for every accessory: a screwdriver, a wrench set and a cordless drill. Fixings are supplied and each item comes with its own instructions.

Accessories ordered at the same time as a greenhouse travel on the same pallet whenever possible. Ordered on their own, they ship separately by parcel or freight depending on size. Shipping is free and fully insured to the 48 contiguous states either way, and tracking is included.

You have 30 days after delivery to request a return. Items must be unused, uninstalled and in their original packaging, with proof of purchase. Contact our team at support@primegreenhouses.com to start a return before sending anything back.
