Description
The Windowsill Seed Spa self watering propagator provides a simple way to start vegetable, herb and flower seed indoors. Its built in reservoir and capillary mat system supply moisture from below, helping to maintain stable compost conditions that support dependable germination and early root formation. Drawing water upward reduces uneven surface drying and limits the need for frequent top watering.
Self Watering Propagator
The lower tray stores water beneath an absorbent capillary mat. Pots or inserts with drainage holes sit on the mat, allowing compost to take up moisture gradually from below and remain evenly hydrated.
A clear impact resistant lid helps retain warmth while allowing strong light to reach developing seedlings. Adjustable vents assist with maintaining balanced humidity levels inside the unit.

Frequently Asked Questions
How often should I top up the reservoir?
Check the water level regularly and refill when it becomes low to ensure a continuous supply of moisture to the compost.
Can standard seed trays be placed on the mat?
Yes. Any pots or inserts with drainage holes can sit directly on the capillary mat to draw moisture from below.
Does the lid remove completely?
The clear cover lifts off easily, providing access for watering, thinning or transplanting seedlings.
Can it be used without water in the reservoir?
Traditional top watering can be used if preferred, though the capillary system is intended to provide more consistent moisture control.
Where should it be positioned?
The propagator can be placed on a window ledge, greenhouse bench or shelf where suitable light is available.
