Introducing the 18ft wide x 40ft long Polytunnel from our VALUE or Garden Choice Polytunnel Range
The Gardener's Choice range are our mid-range polytunnel option. Polythene is attached to a ground TIMBER RAIL rather than been buried. Thus eliminating the need or labour to dig a trench. It is also quicker to build and polythene is clad more tightly to the structure.
What is included in the Gardener's Choice Polytunnel Kit
- High Tensile Z35 Steel Hoops & Bracing 45mm
Steel is up to 20 times more corrosion resistant than standard pre-galvanised tube
- Front *Timber Gable end
- Rear *Timber Gable end with large Net vent (promotes air circulation around plants, but keep pests out!)
- 1 x Set of Double Hinged *Timber doors c/w dropbar and holder for keeping door open
- *Timber Ground rail for sides and gable ends
- Crop Supports for each internal hoop (includes STEEL supporting Down braces)
- 1000G Clear Thermic Anti-Drip Polythene
- Anti Hot Spot Tape (on each hoop and not just the end hoops!)
- UV Repair tape included
- Zip Up/Down Screen for rear net vent
- Polytunnel Building instructions (if building yourself)

All timber is TANELITH-E treated for longer life. What is Tanelith-E?
Ground Rails: How is polythene attached?
Timber Cladding system (Garden Choice range): Polythene is attached to the polytunnel structure by wrapping polythene around timber laths which are then nailed onto the heavier timber ground rail and uprights in gable ends.
Polythene:
Option 1: The standard polythene we use is a 1000G Thermic Anti-Drip Polythene. This is a clear film with the additional benefits of Thermic and Anti-drip properties.
'Thermic' - raises the temperature of the internal temperature by approx.1 to 2 Degrees celsius above the outside temperature.
'Anti-Drip' or 'Anti-Fog' - condensation evaporates or rolls off the polythene.
Option 2: Diffused Thermic 840G Polythene - This is a diffused film with the additional benefits of been Thermic.
'Thermic' - raises the temperature of the internal temperature by approx.1 to 2 Degrees celsius above the outside temperature.
'Diffused' - the sun's rays are 'dispersed' or 'diffused' to prevent plant scorching. The same amount of light is allowed in.
Polythene Warranty: A manufacturer's warranty against UVI degradation of the polythene is 5-6 years depending on the type of polythene picked. This warranty does not cover accidental damage, malicious damage, storm damage or general wear and tear etc.
