Product features

All Cultivar greenhouses feature 4mm toughened safety glass panels set into slim, precision-engineered aluminum frames. This maximises light intake and warmth, creating an optimal growing environment. The glass is secured on both sides with EPDM gaskets, allowing for expansion and ensuring a snug, rattle-free fit. The powder-coated is offered in a choice of Quartz Grey finish (RAL7039) or Oyster White (RAL1013) providing a sleek, maintenance-free appearance.

Large, robust aluminum gutters efficiently channel rainwater from the roof, making it easy to collect pure water for your plants. Adjustable downpipes allow for seamless integration with a water butt, ensuring you make the most of every drop.

Good ventilation is essential for a healthy greenhouse, helping to regulate temperature, reduce humidity, and prevent plant diseases. Our greenhouses are designed with built-in ventilation solutions to ensure optimal airflow and the best growing conditions.

Full-Length Automatic Roof Ventilation – Our greenhouses feature full – length automatic roof vents, which open and close in response to temperature changes. On our planthouses and glass-to-ground models, this works in conjunction with Cultivar’s unique low – level vents to create a chimney effect. Unlike ordinary greenhouses, this system prevents pockets of warm air from forming, ensuring even airflow throughout.

This advanced ventilation system ensures your greenhouse maintains the perfect balance of temperature and airflow, keeping your plants strong and healthy.

A full-length low-level ventilation system runs along the base of the greenhouse, automatically adjusting to temperature changes. This creates a constant flow of fresh air, preventing heat build-up and maintaining the ideal environment for healthy plants.

For greenhouses built on a dwarf wall, our full-length frameless eaves vents provide additional ventilation. Made from toughened safety glass, they operate manually but can be upgraded to automatic openers for hands-free climate control.

Manual vents can be added to the sides of the greenhouse, or on the plain end of the 8′ and 10’8″ wide models. On particularly warm days, opening the door along with these vents allows a steady draught to flow through the greenhouse, helping to keep temperatures in check.

Designed for durability and ease, the Cultivar door offers a tight fit, soft-close action, and thoughtfully designed handles, locks, hinges, and hold-backs. No sticking, no wobbling – just smooth, reliable operation.

Wide enough for a wheelbarrow and with a low threshold for wheelchair access on 8ft and 10ft models, the door’s solid aluminum frame will not warp or twist. Glazed with toughened safety glass at the top and reinforced with heavy-duty Accoya or aluminium paneling below, it’s built for a lifetime of use.

This is not your typical greenhouse door – it’s secure, robust, and practical. A high-spec Eurolock with spare keys, quality inside-and-out handles, and strong hinges allow it to open a full 180 degrees, where a simple retainer holds it in place.

“Integrated boarding is a simple yet effective way to give your greenhouse a more traditional feel – without the cost and complexity of building a wall. Choose from long-lasting Accoya wood or low-maintenance, powder-coated aluminum in Quartz Grey or Oyster White. Beyond adding style, these panels offer a practical solution for concealing the inevitable clutter beneath your staging, from old pots to bags of compost. We call all our boarded models ‘Planthouses,’ and each one comes with our signature low-level ventilation as standard, ensuring optimal airflow for your plants.”

At Cultivar, every aluminum element is meticulously designed with a conscious choice to conceal the engineering. This approach integrates functional components within the profile, making them unobtrusive and maintaining a clean aesthetic. Hidden fasteners and connectors, once the reserve of high-end furniture construction, are now seamlessly incorporated throughout the greenhouse design – ensuring no compromise in both function and appearance. This choice not only elevates the visual appeal but also protects components from environmental factors, staying true to our commitment to thoughtful, user-friendly design.

Our thoughtfully designed workbenches are strong, versatile, and built to last. The slatted aluminum surface provides sturdy support for your plants, with the option to install staging on one or both sides depending on your growing needs. Need a sand bed or pea gravel? Just give us a call to discuss custom options. For added convenience, an ABS plastic potting tray is available for 8ft and 10ft models – perfect for potting up or soaking plants.

A hidden advantage? Fold-down functionality. The staging pivots down in seconds. If needed, it can even be unhooked for complete removal, creating extra space for tall-growing plants like tomatoes in summer.

Matching shelves offer the same flexibility and practicality, designed to make your life easier and to complement your greenhouse perfectly.
