Low Tunnel Kit

Do you want to grow more, for longer, for less? Then a Low Tunnel Kit is the easiest place to start. It uses simple hoops and a protective cover to shield a single garden row or raised bed. So you can plant earlier in spring and keep harvesting later into autumn. Plus, it protects your crops from frost, wind and pests all year. In short, it’s the simplest, most affordable way to extend your growing season.

A low tunnel works like a mini greenhouse over your crops. First, the hoops arch over the row to form a frame. Then you drape a cover over the top and secure the edges. As a result, you create a warm, sheltered micro-climate for your plants. Best of all, it sets up in minutes and moves easily as your crops rotate.

H2: Why Use a Low Tunnel Kit

Low tunnels deliver a lot for a little. To start, they’re far cheaper than a greenhouse or high tunnel. So you protect your crops without a big investment. In addition, they’re portable and flexible. As a result, you can move them around the garden as the seasons and crops change. In fact, many gardeners keep low tunnels in use all year round.

The biggest benefit is versatility. For example, you can pair the hoops with different covers for different jobs. So frost fabric or poly protects against cold, insect netting keeps pests out, and shade cloth shields heat-sensitive crops in summer. Plus, low tunnels warm the soil, which helps seeds germinate and seedlings establish faster. So you get earlier, healthier, more reliable crops.

H2: How to Use Your Low Tunnel

Setting up a low tunnel is easy. First, push the hoops into the soil along your row, spacing them roughly 1–1.5m apart for good support. Next, drape your chosen cover over the hoops. Then pull it taut (but not stretched) and secure the edges. To hold it down, you can bury the edges, or weigh them with soil, sandbags, rocks or timber. Finally, in hot weather, vent or partly remove the cover so plants don’t overheat. As a tip, slitted or perforated covers self-ventilate, so you do less manual venting.

H2: Which Cover Should You Choose?

The cover makes the tunnel, so match it to the season:

• Frost fabric / row cover — lightweight fleece for a few degrees of frost protection in cooler months.
• Poly / greenhouse film — clear plastic for maximum warmth and soil heating in early spring.
• Insect netting / mesh — fine mesh to exclude pests without trapping too much heat.
• Shade cloth — to protect heat-sensitive greens from harsh summer sun.

H2: Low Tunnel vs Greenhouse — Which Do You Need?

These suit different goals, so it helps to compare. A low tunnel is small, cheap and portable, and it protects individual rows or beds. A greenhouse, by contrast, is a permanent walk-in structure for year-round growing. So choose a low tunnel for affordable, flexible season extension. Choose a greenhouse for serious, all-weather growing. For that option, compare our greenhouse range; for larger commercial protection, see our hoop houses and high tunnels.

H2: Siting and Setup

Low tunnels work best in a sunny, fairly sheltered spot. So choose a position protected by a fence, hedge or building where possible, since wind is the main enemy of a low cover. Then anchor the cover well, especially in exposed or windy Australian gardens. Because it’s a small, temporary structure, you generally won’t need council approval. For season-by-season growing advice tailored to Australian conditions, Gardening Australia is a trusted resource, and the Bureau of Meteorology helps you track frost dates and plan your planting.

H2: What to Grow

Low tunnels are brilliant for fast, leafy and cool-season crops. For example, gardeners love them for lettuce, rocket, spinach, kale, beetroot and spring onions. Plus, they help warm the soil for heat-loving crops like tomatoes and capsicums. So you get a head start in spring and a longer harvest in autumn.

H2: Frequently Asked Questions

What is a low tunnel? It’s a mini, hoop-supported cover over a single garden row or bed. So it acts like a small greenhouse to protect and warm your crops.

What can I cover it with? Row cover or frost fabric for cold, poly for maximum warmth, insect netting for pests, or shade cloth for summer heat. So you simply match the cover to the season.

How far apart should the hoops go? Roughly 1–1.5m apart gives good support. In windier spots, space them a little closer.

Will it protect against frost? Yes. Frost fabric or poly gives a few degrees of frost protection and warms the soil, so you can plant earlier and harvest later.
