Garland High Dome Propagator, Large

The Garland High Dome Propagator, Large is a roomy, injection moulded seed propagator built for gardeners who want to raise several trays of seedlings or cuttings at once. The green base tray pairs with a high, ventilated dome lid to trap warmth and humidity around young plants, giving seeds a faster, more even start whether you keep it on a windowsill, greenhouse bench or cold frame.

Key Features

• Large capacity green base tray, ideal as a garden propagator for raising multiple trays of seedlings together
• Two tier drainage holes in the base tray for effective base watering and free drainage
• High dome, ventilated cover with an adjustable dial vent to control humidity and airflow
• Made from durable, largely recycled injection moulded plastic for long term reuse each growing season
• Compact, stackable design that suits windowsills, greenhouses and cold frames

How to Use

• Fill the base tray with good quality seed or cutting compost
• Sow seeds thinly or insert cuttings at the recommended spacing
• Water gently, then fit the high dome ventilated lid to lock in warmth and humidity, which speeds up germination and rooting
• Open or adjust the dial vent on the lid every day or two to release excess condensation and reduce the risk of damping off
• Once seedlings are established, gradually increase ventilation before removing the lid completely to harden plants off ahead of planting out

Frequently Asked Questions

• Is this propagator heated? No, this is an unheated, passive propagator. It works by trapping the sun's natural warmth and the moisture given off by compost and seedlings under the dome, rather than by any electrical heating element.
• What size seed trays does it fit? The base tray is sized to take a standard full size seed tray, so you can lift trays in and out easily for watering or moving between locations.
• How do I stop the lid misting up too much? Use the adjustable dial vent on top of the dome to let excess humidity escape. A little condensation is normal, but daily venting helps prevent damping off in young seedlings.
• Can I use it for cuttings as well as seeds? Yes, the high dome gives extra headroom compared with a standard propagator lid, making it well suited to taller cuttings as well as seed trays.
