Greenhouse

PRIMATERRA PLUS Greenhouse 300x1000x210 cm, Galvanised Steel Frame with 4 mm Polycarbonate

30 m² of covered growing space for a season that lasts almost all year, with cladding that stays on through winter.

The PRIMATERRA PLUS greenhouse measures 300x1000x210 cm and gives you 30 m² of protected growing space for tomatoes, cucumbers, herbs and seedlings. Its arched frame is built from double-galvanised 20x20x1 mm square tube and clad in 4 mm UV-protected polycarbonate. Everything needed for assembly is in the box, including two doors with vent windows.

Snow load rated to 100 kg/m²

The welded arched base of 20x20x1 mm square tube carries the winter load, while the curved roof helps the snow slide off. The polycarbonate stays in place over winter, so the greenhouse is ready for early sowing.

4 mm polycarbonate with UV protection against leaf burn

The twin-wall sheets let light through while filtering ultraviolet rays, so plants are not scorched on hot days. Heat retention is close to that of glass, which is what extends the early and late growing periods. The sheets are fixed with self-tapping screws with rubber seals and washers.

Two doors with vent windows for airflow along the full length

Each end panel carries a door with an extra window, so opening both draws air through the full 10 m and evens out the temperature. A roof vent can be fitted separately when stronger ventilation is needed.

Installation into soil or onto a foundation

The uprights can be sunk straight into the ground or bolted to a prepared foundation, depending on your plot. Galvanising inside and out protects the steel from corrosion, with no extra anti-rust treatment needed. Assembly follows the supplied instructions and needs no specialist tools.
