About Grodan A-OK Starter Plugs

A-OK Starter Plugs is manufactured using Grodan's stonewool process, in which molten rock is spun into fibers and compressed into a consistent, sterile growing medium, a method the brand applies across its full propagation and slab lineup.

Frequently Asked Questions

How do A-OK Starter Plugs fit into a propagation tray?

The strip format is built to fit a standard 10in x 20in propagation tray, so growers can drop plugs directly into a tray without cutting or trimming. Each plug measures 2in x 2in x 1.6in, sized for seed starting or cutting propagation.

What's the difference between this listing and item# GRD293826?

This listing is the non-shrink-wrapped version, while GRD293826 is the same 2in Pro plug in shrink-wrapped packaging. Growers choose based on storage and handling preference rather than a difference in the plug itself.

Can these plugs be used for both seeds and cuttings?

Yes, Grodan's A-OK Starter Plugs are built for both starting seeds and rooting cuttings. That dual use makes a single plug format work across different propagation stages in the same tray.

What is the plug made from?

Like Grodan's other propagation products, A-OK plugs are stonewool, made by spinning molten rock into fibers and compressing them into a consistent growing medium. That structure holds moisture while still allowing oxygen to reach developing roots.
