Grodan Cress Plate

Grodan Cress Plate is a stone wool substrate for microgreens and baby leaf crops, built for quick and easy germination and uniform early growth. This stone wool growing media is designed as a thin grow plate for fast, intensive greens production where evenness matters from edge to edge.

One of the defining features is that it’s the thinnest Grodan product available, created for quick growing crops that need minimal substrate. The consistent structure supports quick and easy germination, helping starts come up evenly so the crop can move forward together. For growers who care about repeatability, that consistent structure is a big reason the plate stays dependable from batch to batch.

Grodan Cress Plate is also built around uniform density, which supports uniform water levels throughout the product for even crop growth. In practical terms, that uniform density helps keep moisture distribution more even across the plate, supporting steadier crop development during short cycles. The fine fibrous structure is designed for young, tender roots to explore, supporting fast root development in the earliest stage without relying on bulky media.

For production teams that want a clean, streamlined format, this thin stone wool grow plate is positioned for professional microgreen production and micropropagation. It’s designed to sit neatly inside a standard propagator dome, making handling simple during early-stage work while keeping the growing surface consistent. If you’re growing microgreens such as arugula, basil, chives, or watercress, the plate format is built to support uniform and quick crop development that’s easier to harvest and easier to standardize.

This product is a good fit for growers focused on microgreens and baby leaf crops who want a thinnest-in-range stone wool substrate with uniform density, uniform water levels, and quick and easy germination for even crop growth.
