Sunshine GardenStarter Kit

Do you want to start growing, but you’re not ready for a full greenhouse? Then the Sunshine GardenStarter Kit is the perfect place to begin. It’s a compact, portable cold frame — a mini greenhouse that shelters your seedlings and young plants from cold, wind and pests. Above all, it’s affordable, easy to use and small enough to fit almost anywhere. So it’s the ideal first step into year-round gardening.

Despite its small size, it’s built with real quality. In fact, it uses the same natural redwood frame and twin-wall polycarbonate panels as the larger Sunshine GardenHouse models. So you get genuine durability and insulation in a starter-sized package. Plus, the lightweight frame makes it easy to move around the garden — or even bring indoors.

Why Choose the GardenStarter Kit

A cold frame is the smartest way to get growing. To start, it creates a warm, sheltered micro-climate for seeds and seedlings. As a result, you can start your garden earlier in spring and harden off young plants with ease. In addition, it protects tender growth from frost, wind and hungry pests. So more of your seedlings survive and thrive.

The GardenStarter is designed for convenience. For example, the bed fits four standard seedling flats, so you can raise plenty of plants at once. In addition, built-in ventilation keeps the temperature and airflow just right. Plus, the rigid, lightweight redwood frame lifts and moves easily. So you can chase the sun, or shift it indoors when the weather turns. Better still, you can plant directly in the soil beneath it, or grow in containers inside.

H2: GardenStarter vs Mini vs Patio GardenHouse — Where to Begin

The Sunshine range scales up neatly, so it’s easy to grow with it. The GardenStarter is the smallest and most affordable — a portable cold frame for seed starting and small-space growing. The Mini Sunshine GardenHouse steps up to a compact 6′ x 4′ walk-up greenhouse. The Patio GardenHouse is a lean-to that fits against a wall. So choose the GardenStarter to dip your toes in, then move up to a walk-in greenhouse as your gardening grows. For larger walk-in options, see our greenhouse range.

H2: How to Use Your Cold Frame

A cold frame is wonderfully simple to use. First, place it in a sunny, sheltered spot — against a wall or fence works well. Next, sow seeds in the soil below, or fill it with trays and pots. Then vent it on warm days so plants don’t overheat, and close it up at night for warmth. As a tip, move it to follow the sun through the seasons. For season-by-season sowing and growing advice in Australian conditions, Gardening Australia is a trusted resource, and the Bureau of Meteorology helps you track frost dates.

H2: What to Grow

A cold frame is brilliant for getting a head start. For example, use it to raise seedlings of tomatoes, capsicums, herbs and flowers before planting out. Plus, it’s perfect for hardening off young plants and growing leafy greens like lettuce and rocket. So you extend your season at both ends, from a small, simple kit. For more ideas, Gardening Australia has excellent seasonal guidance.
