Plastic tunnels can provide rain protection and a modified growing environment for selected vegetable crops, but their performance depends on structure and operation.
Anchoring and bracing should respond to site exposure, while side ventilation and access should support the crop rather than being treated as optional accessories.
Drip irrigation is commonly integrated because rainfall is excluded from the protected bed. Drainage outside the tunnel is equally important during heavy rain.
Before requesting a tunnel quotation, define width, length, crop, season, site exposure and whether insect net, doors, trellising or irrigation are part of the scope.
