Polyeco Tube Greenhouse

The Polyeco Tube is a practical 3m-wide greenhouse designed around one simple advantage: maximum usable space inside.

Unlike several other Polyeco models, the Tube has no internal support bars, so the whole enclosed area remains open and easy to use for beds, shelving, tall crops and general movement.

4mm or 6mm Polycarbonate

The Tube is available with either 4mm or 6mm twin-wall polycarbonate.

Both options provide good light transmission and a practical, shatter-resistant alternative to glass.

Choose 4mm for the best balance of performance and price, or 6mm if improved insulation and heat retention are more important.

Galvanised Steel Tube Frame

The frame is built from 20mm × 20mm galvanised steel tubing, with arches spaced approximately 67cm apart.

The structure is strong enough for normal garden use while keeping the interior free from extra support bars.

Ground Anchoring System

The Tube uses the same ground anchoring principle as our other Polyeco greenhouses.

Each arch is secured using T-shaped ground anchors, allowing the greenhouse to be installed directly onto suitable soil or grass without normally requiring a concrete base.

Open, Usable Interior

The Tube’s main advantage is space.

With no internal bracing bars, the greenhouse gives you a clean interior that is easy to organise around:

• Growing beds

• Shelving

• Tall crops

• Central walkways

• Irrigation

• General storage and working space

Available in a Range of Lengths

The Tube is 3m wide and available in standard lengths of:

2m, 4m, 6m, 8m, 10m and 12m

Longer and custom lengths are also available on request.

Best Suited To

The Tube is a strong and practical greenhouse for most normal garden locations.

However, because it has no internal support bars and a lighter structural design than the Classic, it is not our first recommendation for very exposed sites or areas with particularly heavy snow loads.

For those locations, the Polyeco Classic is the stronger option.

Optional Extras

The Tube can also be fitted with:

• Roof vents

• Rear door

• Shelving

• Raised beds

• Other compatible accessories
