Plastic seedling trays Prosperplast KBILS20-3020 — 5 pcs, long cells, 198×118×155 mm, red

Prosperplast KBILS20-3020 is a pack of five rigid red plastic seedling trays designed for sowing, propagation and short-term transport of young plants. Each tray measures 198×118×155 mm and contains long, individual cells that support root development of seedlings and cuttings. The trays are stackable and reusable, suitable for hobby gardeners, nurseries and home propagation tasks.

Advantages

The long cell shape provides extra depth for root systems, reducing the need for early transplanting and encouraging stronger root development. Constructed from durable rigid plastic, these trays resist bending and are straightforward to clean and reuse. Their compact footprint and stackable design simplify storage and allow efficient use of greenhouse benches or indoor shelves.

How to use

Fill each cell with a suitable seed-starting mix or propagation medium, press seeds or cuttings to the recommended depth and water gently to settle the substrate. Place trays in a bright location with appropriate temperature and humidity for the species being grown. Monitor moisture levels and water from below or lightly from above as needed. When roots have filled the cell or when seedlings show adequate true leaves, transplant into larger pots or into the ground following standard hardening-off procedures.

Usage recommendations

Clean trays after each use by removing substrate and rinsing with water; for tougher residues, use mild detergent and allow to dry completely before storing. Avoid prolonged exposure to direct sunlight when not in use to reduce UV-related material degradation. Use a well-draining seed mix and maintain consistent moisture to promote uniform germination and healthy root development.
