Know before you buy
No, the netting is designed to be fully decomposable. You can plant the entire pellet directly into your garden or larger pot, which helps prevent root disturbance during the transplant process.
Place the sheets in a standard propagation tray and add warm water to the bottom of the tray. The peat will absorb the moisture and expand to its full height of approximately 2 9/16 inches within a few minutes.
These sheets are designed to fit standard 10-inch by 20-inch propagation trays, including 22-inch by 11-inch Perma-Nest trays. They are sized to sit securely within the tray base to prevent shifting.
Yes, the 'extra deep' design provides a 42 mm diameter and over 2.5 inches of depth, which offers significantly more room for root development compared to standard-sized pellets. This makes them an excellent choice for cuttings or seeds that require a deeper root system before transplanting.
Because the peat medium is designed for high moisture retention, check the pellets daily. If the surface feels dry to the touch, add a small amount of water to the bottom of the tray to allow the pellets to wick up the moisture as needed.
