Tired of the mess and waste that comes with soil and coco coir? Our 10x10 reusable stainless steel grow medium gives you a rigid, soil-free surface that cuts down on single-use growing materials and simplifies your setup. Pre-cut to fit standard 10x10 trays.
Key Specifications
- Pre-Cut Dimensions: 9.25" x 9.25", fits standard 10x10 microgreen trays perfectly
- Hole Size: 1mm, great for root development and moisture retention
- Material: 316-grade stainless steel mesh
- Durability: Corrosion resistant, long-lasting, and highly resistant to cutting or tearing
- Customization: Can be trimmed with tin snips for custom sizing
- Lifespan: Months of continuous use with proper care
Why Growers Choose Stainless Steel
The rigid steel mesh gives excellent structural support and longevity, so the sheet stays flat while roots take hold. It is the better pick if you want maximum durability, aggressive cleaning options, and a surface that will not tear.
Works well with most popular microgreen varieties including Sunflower, Radish, Broccoli, Arugula, Basil, Cabbage, Kohlrabi, and most Brassica family crops.
Care and Maintenance
- Cleaning: After you harvest, use our Microgreen Medium Scraper/Cleaning Tool to remove root residue.
- Sanitization: Stainless steel handles aggressive cleaning methods including boiling water or commercial food-grade sanitizers rated for stainless steel.
- Caution: The edges can be quite sharp and may penetrate skin. Handle with care, especially during initial setup and cleaning. Edges may become frayed or bent during shipping.

Seed Compatibility
✅ Works Well With: Sunflower, Pea, Radish, Broccoli, Kale, Cabbage, Arugula, Basil, Mustard Greens, Kohlrabi, and most Brassica varieties
⚠️ More Challenging: Amaranth can grow successfully at 75°F with proper heat mat management. Very fine seeds may require adjustments depending on your setup.
❌ Not Recommended: Swiss Chard, Beets, and Cilantro, which perform better in soil or coco coir
💡 Best Without a Medium: Pea varieties with aggressive root systems often perform best directly on mesh trays without a grow medium.

Start Small, Scale Confidently
If you are new to reusable grow mediums, we recommend starting with a 2-pack to test the setup in your environment. Once you are dialed in, 10-packs offer better value for higher-volume growing.
Prefer Silicone?
We offer this same 10x10 pre-cut size in food-grade platinum-cured silicone if you want a flexible surface that is easier on your hands at cleanup. Not sure which suits your setup? Our 10x10 Sampler Pack includes both materials so you can test them side by side.
