Rowlinson Greenhouse in a Box

The Rowlinson Greenhouse in a Box is a smart, portable greenhouse solution designed to help you grow and protect your plants with ease. Whether you’re an experienced gardener or just starting out, this shelter offers the ideal environment to nurture seedlings, vegetables, herbs, or flowers all year round. Built with a 35mm high-grade steel frame, it features a premium powder-coated finish that resists chipping, rust, and corrosion. The structure is reinforced with patent-pending ShelterLock® 3X steel stabilisers, which ensure added strength and rigidity, even in unpredictable weather. The cover is made from a triple-layer, heat-bonded ripstop polyethylene fabric that’s UV-treated inside and out. This design allows enhanced light transmission for optimal plant growth, while also offering excellent waterproofing to shield your crops from rain and moisture. Ventilation is made simple with EasyFlow™ side panels, which can be rolled up and secured with bungee fasteners, or kept down using hook-and-loop fasteners. This gives you full control over temperature and airflow inside the greenhouse. The Ratchet Tite™ tensioning system ensures the cover fits drum-tight over the frame, offering a snug and secure fit throughout the seasons.

Roof Tiles & Fittings:

We recommend ordering an additional 10% of roof tiles to allow for any breakages that may occur during delivery or handling. Roof tiles are naturally fragile, and having a few extra on site helps prevent delays and ensures your roofing project can be completed without interruption.
