Garland Big 3 Electric Propagator – Variable Thermostat

A Big Growing Space With Its Own Thermostat

The Garland Big 3 is the largest electric propagator in Garland's range, built for gardeners raising seeds or rooting cuttings in real volume. It pairs three large high dome propagators, each 37.5cm long by 23cm wide, with a heated base that carries its own fixed-temperature thermostat, so the unit runs itself once it's switched on.

Key Benefits

• 50W carbon fibre heating element spreads warmth evenly across the whole base rather than in hot spots
• Fixed thermostat holds the compost at around 19°C, the temperature most seedlings and cuttings root well at
• Three large high dome sections, 37.5cm x 23cm each, give plenty of headroom for taller young plants
• 'Heat On' and 'Power On' neon indicators show at a glance that the base is working
• Footprint of 80.5cm x 41cm suits a greenhouse bench or a spare-room table

Even Warmth Without Watching a Thermometer

Seeds and cuttings root fastest at a steady compost temperature, but an unheated tray left on a cool greenhouse bench or a draughty windowsill can sit several degrees below that all day. The Big 3's heated base keeps the compost close to 19°C automatically, so germination and rooting stay on track without a heat mat, a separate thermostat, or repeated manual checks.

How to Use

• Fill each dome's tray with moist compost or rooting medium and sow seed or insert cuttings as normal
• Fit the high dome lids and set the unit on a level, stable surface away from draughts
• Plug in — the base thermostat maintains the compost at around 19°C automatically, with 'Power On' and 'Heat On' neons confirming it's running
• Vent the dome lids as seedlings develop to manage humidity and reduce the risk of damping off
