About Grodan A-OK

Grodan's A-OK Starter Plugs use a V-shaped stonewool design across several packaging formats, including this loose bulk case, all sized to seat directly into the pre-cut holes on Grodan's Gro-Block line.

Frequently Asked Questions

What does the V-shape design in this plug do?

The V-shape deters root tangling as the plug fills with roots, helping a rooted cutting or seedling transition into a larger block without the roots knotting around themselves. That's the same design used across Grodan's other A-OK plug formats.

How is this loose-case format different from A-OK plugs sold in sheets?

This format ships as 2,310 individual loose plugs rather than connected in perforated sheets or strips. Commercial operations that load plugs directly into trays at volume often prefer loose packaging over breaking apart sheets first.

What crops are A-OK Starter Plugs suited for?

They're commonly used for propagating lettuce, leafy greens, and culinary herbs, among other crops suited to hydroponic and stonewool propagation. The pre-cut hole works for both seeds and small rooted cuttings.

Do these plugs fit Grodan's Gro-Block line?

Yes, the 1.4in x 1.4in x 1.6in pre-cut hole is sized to seat into the pre-cut holes on Grodan's Gro-Block products for a gap-free transplant. That sizing is shared across Grodan's plug and block lines.
