Seedling Hydroponic Sponge Sheet (100 Pods)

Reliable soilless starter medium for healthy seedlings.

This Seedling Hydroponic Sponge sheet provides a clean, consistent growing medium for starting seeds without soil. Made from durable PU sponge, each sheet measures 250mm x 250mm x 24mm and is pre-cut into 100 uniform squares (25mm x 25mm x 24mm). The open-cell structure absorbs and retains water efficiently, keeping seeds evenly moist while allowing air to reach developing roots.

Designed for hydroponic and soilless systems, these sponge squares fit easily into most seedling trays, net cups, and small plant containers. Simply moisten the sheet, insert your seeds into the pre-cut squares, and place in your chosen system or nursery tray. The consistent moisture and structure help promote strong root development, making transplanting smoother and improving seedling survival rates when moved to larger systems or containers.

Why It's a Smart Choice

• Clean, soilless germination - Ideal for hydroponic setups and indoor growing where you want to avoid mess and soil-borne issues.
• Consistent moisture retention - Sponge structure holds water evenly, helping prevent seeds from drying out or becoming waterlogged.
• Easy transplant and handling - Individual squares support intact root systems, reducing stress on seedlings during transfer.
