Bio Dome Planting Blocks

Endlessly Reusable, Lightweight and Sturdy

Bio Dome planting blocks are made of Styrofoam, so they float easily yet are quite strong. The individual Bio Sponge holes are tapered, giving plant roots access to the water in the base of the tray. At transplant time, it's easy to up-end the planting block and gently push the seedlings out!
