Gardman Grow It Perma Grow Tunnel Single

Gardman Grow It Perma Grow Tunnel Single is a reusable, heavy-duty propagation tunnel designed to create a sheltered microclimate for seedlings, salads and young plants throughout the UK growing season. The 2 metre long steel-framed tunnel with a clear PVC cover warms the soil, protects early sowings from cold and wet weather, and lets in plenty of light for healthy, vigorous growth.

Ideal for placing directly over a row in the vegetable plot, along a prepared seed bed, or inside a larger greenhouse for added frost protection, this grow tunnel gives reliable year-after-year performance. The clear cover allows sunlight to reach plants whilst retaining warmth and humidity, helping germinating seeds establish faster and extending the growing season at both ends.

Built around a strong steel frame with a heavy-duty clear PVC cover, the Perma Grow Tunnel is designed to be reused for many seasons. Zipped roll-up doors at both ends give easy access for watering, weeding and harvesting, and a netted side window provides adjustable ventilation on warmer days. Simple to set up with no tools required, the tunnel folds flat for tidy winter storage.

Assembly & Use

• Position: Place the tunnel over a prepared row or seed bed, leaving enough room on either side for the frame to sit flat against the ground.
• Set up: Push the steel frame hoops into soft soil at even intervals along the row; the cover slots over the top and fixes into place.
• Access: Unzip the roll-up doors at either end to water, weed or harvest; use the netted side window to increase airflow on warm days.
• Storage: At the end of the season, wipe the cover clean, fold flat, and store undercover through the winter to maximise its lifespan.

Where to Use

• Vegetable plot: directly over rows of salads, carrots, beetroot, radish, and other home-grown crops.
• Seed beds: protects newly-sown seeds and emerging seedlings from cold, wind, heavy rain, and pests.
• Greenhouses: can be used inside a larger greenhouse for an extra layer of frost protection on tender plants.

When to Use

• Spring: place over the soil 1–2 weeks before sowing to warm the ground and encourage earlier germination.
• Summer: use the netted side window and open the zipped ends to prevent overheating in hot weather.
• Autumn: extend the season for late sowings, salads, and young plants into the first frosts.
