Our take on the Rockwool Cube for Hydroponics,Stonewool Grow Cubes Starter Plugs,Garden Rock Wool Propagation Sub,Seed Starter Plugs,Rock Wool Planting Cubes for Soilless Culture and Transplanting,50 Pcs,Topboutique

These are small cylindrical rockwool starter plugs for hydroponic seed starting and transplanting. Each plug measures about 1 inch tall and 0.8 inch across, and the pack holds 50. Rockwool holds moisture while letting air reach the roots, which is why it is a standard medium for cuttings and seedlings. The small size suits seed trays and net pots rather than large plants, so check the plug against your pot opening before buying.

Questions and answers

What size are the plugs?
Each plug is about 1 inch tall and 0.8 inch across, a round cylinder. That fits standard seed trays and small net pots.
Do I need to soak them before use?
Yes. Rockwool is alkaline out of the pack, so soak the plugs in pH-adjusted water before sowing or inserting cuttings.
Can I use these for cuttings as well as seeds?
Yes. The firm cylinder holds a stem upright while roots form, and the same plugs work for germinating seeds.
Are they reusable?
No. Once roots grow through the wool, the plug breaks apart on transplant and is discarded.
How many plugs come in a pack?
The pack contains 50 plugs, enough for a full tray of seedlings.
Is rockwool safe to handle?
The fibers can irritate skin and lungs. Wear gloves and avoid breathing the dust when separating or handling the plugs.
