IHORT Q Plug 18/40 3/4” top X 1-1/2” deep, Case of 3,250

Square Propagation Plugs Engineered for Fast Rooting, 18/40

Propagation plugs with weak air porosity or poor water control slow root development and leave more cuttings failing to establish. IHORT's 18/40 Q Plug is engineered specifically for fast rooting and reliable transplanting, sized at 3/4 inch at the top by 1-1/2 inch deep.

There are 3,250 square plugs per case, each built to provide more air porosity and water control than many standard propagation media, supporting stronger roots and, in turn, healthier transplants.

Frequently Asked Questions

How many plugs are in a case?

3,250 square plugs per case. That count is sized for commercial-scale propagation runs.

What are the plug dimensions?

Each plug measures 3/4 inch at the top by 1-1/2 inch deep. That shape is sized for the 18/40 tray format this plug is built for.

What benefit do these plugs offer over standard media?

They offer more air porosity and better water control than many standard propagation media. Together, those properties support stronger root growth.

How do I know when plugs from this case are ready to transplant?

Watch for visible root development reaching the outer edges of the plug before moving it into its next container. Transplanting too early risks disturbing roots that haven't fully established.
