Cultiwool 84 Cell Rooting Plug Sheets - 19.6 x 8.4 x 1.6-in - Stonewool - Shrink Wrapped - 25 Count

Uniform Stonewool Cells for Propagation at Scale - 25 Sheets

Starting seeds and cuttings in uneven media leads to uneven roots and uneven transplants. These stonewool rooting plug sheets give every cell the same shape and firmness, so your starts develop on a consistent footing. Stonewool is an inert medium, so it does not lock up or release substances that would interfere with water and nutrients reaching the plant.

Each unit contains 25 sheets of 84 cells, which suits growers who propagate on a regular schedule. Hobbyists running occasional batches can work through the sheets over several rounds, and commercial operations can use them as a steady supply for propagation rooms.
