Professional Plastic Seedling Trays – Dutch Standard (54×28 cm)

Professional plastic seedling trays (seed starting trays) of the Dutch Standard (size 54×28 cm) are a tool created specifically for those who value stable results, high germination rates, and strong seedlings. Thanks to a precisely thought-out design and durable materials, these trays guarantee identical development conditions for every plant. The 54×28 cm standard is recognized as optimal worldwide, as it is perfectly suited for mechanized sowing, transportation, and care. This is the exact format that ensures the maximum percentage of successful transplanting (survival rate) and the rapid development of a healthy root system.

These trays are used by professional greenhouse farms, farmers, landscape designers, and private gardeners who aim to obtain the strongest possible planting material without unnecessary costs.

Key Advantages

• Durability: Made for multiple reuses.
• Ideal Cell Design: The conical shape and ribs prevent the roots from spiraling (root circling).
• Optimal Drainage: Precise drainage holes protect the roots from overwatering.
• Easy Transplanting: Allows seedlings to be planted out without stress to the plants.
• Cost-Effective Investment: Direct deliveries from the manufacturer ensure the best balance between price and professional quality.

Comprehensive Solution for Maximum Efficiency

For achieving the best results, we recommend using complementary products:

• Seedling Trays with Drip Trays (Flats): The flat ensures uniform bottom watering and convenient, safe transport of a large number of seedlings.
• Seedling Trays with Lids (Mini-Greenhouse): Using a lid creates an ideal microclimate (greenhouse effect), which significantly accelerates and promotes uniform seed germination.
