Features larger, deeper compartments specifically designed for plants that require extra root room and hate root disturbance.

Proudly sized to fit flawlessly inside British Standard seed trays and gravel trays, these recycled plastic inserts are perfect for autumn sweet peas, broad beans, garlic starts, and deep-rooted vegetable plugs. With 15 generous cells per tray, this pack gives you a total of 150 large individual cell capacity to give your autumn crops the strongest possible start.

Lightweight & Easy-Pop Design: These inserts are specifically engineered as pliable, lightweight propagation trays. The flexible recycled plastic allows you to gently squeeze the base of each individual cell to pop young plug plants out cleanly without damaging delicate, developing root systems.
