Grodan Smart Tray

Grodan Smart Tray is a double-sided propagation tray insert for holding Grodan stone wool plugs and blocks during propagation from seed or cuttings. Built as a propagation accessory and bench organizer, it helps keep early-stage starts aligned, separated, and easier to handle from one cycle to the next.

The double-sided tray insert design gives you two practical working surfaces in one tool. One face is a structured cell side designed for Grodan A-OK starter plugs and Grodan Macroplugs, keeping individual starts steady and spaced for repeatable handling. Flip it over and the mesh side supports sheet-style layouts of Grodan A-OKs, Grodan Mini-Blocks, or Grodan Gro-Blocks, which helps keep larger sets of stone wool media positioned neatly and consistently.

Because it’s a structured holder rather than an open flat, Grodan Smart Tray supports a more uniform workflow during routine checks and moves. The defined layout helps reduce shifting, which can make propagation areas feel more controlled and more consistent across batches. It’s also designed to keep stone wool positioned above the bottom surface of the tray it sits in, helping reduce direct contact between the media and standing runoff.

Growers often choose this style of propagation tray insert for cleaner handling and healthier early root-zone conditions. The tray design is described as improving airflow around cuttings, supporting a more even environment across a full tray. A rounded mesh support at the bottom of each cell is also intended to help reduce root damage when lifting starts, which can matter when you’re moving young plants forward on a tight timeline. For day-to-day maintenance, it’s described as easy to sanitize like a hard-plastic product, with dishwasher safe cleaning convenience in busy grow rooms.

This tray insert is a good fit for growers who want a double-sided tray insert that keeps stone wool propagation media organized, supports repeatable handling, and helps standardize plug and block management across ongoing propagation cycles.
