Seed Tray and Propagator Set - Medium - Green - With Lid

Yes, this tray is suitable for use on standard horticultural heat mats to further boost germination temperatures.

It is recommended to hand wash the lid with warm, soapy water to prevent warping from high dishwasher temperatures.

This model is a base tray and lid set, perfect for using with individual cell inserts or as a flat seed-starting bed.

While it can be used in a greenhouse or cold frame, it is primarily designed for indoor use to maintain stable warmth.

The tray itself is 6cm tall; the total height including the lid provides sufficient clearance for initial seedling growth.

Lift the lid for 1-2 hours daily to allow airflow and prevent mold growth on the soil surface.

The plants are seeking more light; move the propagator to a brighter windowsill or closer to your artificial grow lights.

Ensure the tray is not sitting directly in a solid basin; if you use a secondary saucer, empty it regularly to allow the drainage holes to function properly.
