Garland High Dome Electric Propagator, XL

The Garland High Dome Electric Propagator XL is the largest heated propagator in the Garland range, combining a generous base tray with a clear, high dome ventilated cover and a 24 Watt heating element. It is built for gardeners and small growers who want to raise a big batch of seedlings or cuttings together, with the extra height in the dome giving taller plants room to grow before they need potting on.

Key Features

• Extra large injection moulded base tray with a clear, high dome ventilated cover for maximum growing space
• 24 Watt heating element built into the base for gentle, even warmth across the whole tray
• Non thermostatically controlled, fixed heat output that raises compost temperature by around 8 degrees Celsius above ambient
• Tall dome design gives extra headroom compared with standard propagators, suiting larger seedlings and cuttings
• Economical to run thanks to its low, fixed wattage heating element
• Suitable for seeds, cuttings, vegetables, flowers and herbs

How to Use

• Place the propagator on a stable, dry, level surface, such as a greenhouse bench or potting shed table, away from any water source before plugging in
• Fill the base tray with compost, sow seeds or insert cuttings
• Fit the high dome ventilated lid to trap warmth and humidity, then plug into a suitable mains socket, keeping the cable clear of watering cans, hoses or damp benches
• As the heat output is fixed rather than thermostatically controlled, monitor compost moisture closely since the added warmth speeds up drying compared with an unheated propagator
• Adjust the vents on the dome lid to release excess humidity and help prevent damping off in young seedlings
• Once seedlings are well established, gradually increase ventilation before removing the lid completely to harden plants off ahead of planting out

Frequently Asked Questions

• Is the XL High Dome propagator thermostatically controlled? No, Garland lists this as a non thermostatic, fixed output heated propagator. The 24 Watt element raises compost temperature by approximately 8 degrees Celsius above ambient rather than holding a set target temperature.
• What does it cost to run? At 24 Watts it uses roughly the same power as a small light bulb, so running costs are modest even used daily through a growing season, though your exact cost depends on your electricity tariff and hours of use.
• What safety precautions should I take? Use it on a dry, stable, level surface away from water ingress, do not immerse or hose down the base, keep the mains cable away from damp areas, and always follow the instructions supplied with the unit before first use.
• Is it big enough for a full greenhouse bench? At 59 x 41 x 26.5cm this is the largest propagator in the Garland electric range, with enough tray space and dome height for a substantial batch of seedlings, young vegetable plants or taller cuttings.
