Start your seedlings strong with this 45-hole deep seedling tray, designed for healthy root development and robust growth. Its 4.5-inch depth allows plants to establish deeper roots compared to standard 1.7-inch trays, making it ideal for vegetables, herbs, and flowers that need a strong early start.

Key Features

• Deep 4.5-inch cells: Encourages stronger root systems and reduces transplant shock.
• 45 individual cells: Perfect for batch starting multiple seedlings at once.
• Durable material: Long-lasting and reusable for multiple growing seasons.
• Optimal drainage: Prevents waterlogging while keeping soil moist.
• Versatile use: Suitable for vegetables, herbs, and flowering plants like tomatoes, chillies, basil, and marigolds.

Why Choose Deep Over Standard Tray

• Deeper trays support root development, reducing the need for frequent transplanting.
• Ideal for plants that grow fast or require strong roots for early growth.
• Minimizes root crowding and improves overall seedling survival rate.

How to Use

• Fill each cell with a seed-starting mix or a blend of soil and vermicompost.
• For tomatoes and chillies, sow about 1/4 inch (6 mm) deep in fine seed-starting mix. For light-germinating flowers such as petunias, press the seeds onto the surface and leave them uncovered.
• Water gently and place in a well-lit area or under grow lights.
• Move seedlings on when their roots hold the plug together. Lift by the rootball, and gradually introduce indoor-grown plants to outdoor light and wind before planting outside.
