Description
Three Sections, No Heating Bill
The Garland Three Top is a simple, unheated propagator sized for a windowsill, giving three separate high dome sections in one long, narrow tray. It's built for gardeners who want the humidity and warmth benefit of a covered propagator without an electrical base to plug in.
Key Benefits
- Three separate high dome sections, each 23cm long by 17cm wide, for growing several varieties at once
- No power connection needed — relies on natural windowsill warmth and light
- Long, narrow 76cm x 18.5cm footprint designed to sit along a sill
- High dome lids trap humidity around seedlings and cuttings to support even germination
- Fully injection-moulded rigid plastic construction for repeat seasonal use
Trapping Humidity Without an Electrical Base
Seeds and cuttings root and germinate faster in a humid, sheltered environment, but not every windowsill needs — or has room for — a heated unit. The Three Top's high dome covers hold humidity around the compost using the sill's own warmth, giving seedlings a head start with nothing to wire in.
How to Use
- Fill each of the three trays with moist compost or seed compost and sow seed, or insert cuttings
- Fit the high dome lids and stand the unit on a warm, bright windowsill
- Check compost moisture regularly, since the covers hold humidity in rather than adding heat
- Lift the domes off, or open them, once seedlings are established to acclimatise them before moving on
Technical Specifications
- Sections: 3 high dome propagators
- Dome size (each): 23cm long x 17cm wide
- Overall size: 76cm long x 18.5cm wide x 20.5cm high
- Heater: none (unheated, relies on ambient warmth)
