Garland Super 7 Electric Windowsill Propagator, 76 x 18.5 x 15cm, 13 Watt

The Garland Super 7 Electric Windowsill Propagator is a long, narrow heated propagator designed to fit neatly along a windowsill while giving you seven individual mini propagators for growing several varieties of seeds or cuttings at once. A gentle 13 Watt heating element takes the chill off draughty windowsills, helping seeds germinate faster and more evenly than they would in an unheated tray.

Key Features

• Seven individual mini propagator sections, each with its own ventilated lid, ideal for growing multiple seed varieties side by side
• Slim 76 x 18.5 x 15cm footprint purpose built to fit a typical windowsill
• 13 Watt carbon fibre heating element built into the base for even, gentle warmth
• Non thermostatically controlled, fixed heat output that raises compost temperature by around 8 degrees Celsius above ambient
• Helps counter cool, draughty windowsills that would otherwise slow down germination

How to Use

• Stand the propagator on a stable, dry, level windowsill or bench away from any water source before plugging in
• Fill each of the seven mini propagator trays with compost and sow seeds or insert cuttings
• Fit the ventilated lids to trap warmth and humidity, then plug into a nearby mains socket, keeping the cable away from taps, sinks or watering cans
• As this is a fixed heat, non thermostatic unit, keep an eye on compost moisture since the extra warmth can dry it out more quickly than an unheated propagator
• Open the lid vents daily to release excess humidity and reduce the risk of damping off, following the safety guidance supplied with the product
• Once seedlings are established, gradually increase ventilation before removing the lids completely to harden plants off before planting out

Frequently Asked Questions

• Is the Super 7 thermostatically controlled? No, it is a fixed output, non thermostatic heated propagator. The 13 Watt element raises compost temperature by approximately 8 degrees Celsius above the surrounding air rather than holding it at a set target.
• Is it safe to run on a windowsill near a window? Yes, provided it is used on a dry, stable surface away from direct water contact such as drips from watering or condensation pooling around the plug. Always follow the instructions supplied with the unit and avoid leaving it somewhere the mains cable could get wet.
• What does it cost to run? At 13 Watts this is a low power appliance, so running costs are modest even left on for long periods, though the exact cost depends on your electricity tariff and hours of use.
• Why is it shaped so long and narrow? The 76 x 18.5 x 15cm footprint is designed specifically to fit along a standard windowsill while still giving room for seven separate mini propagators.
