Hydroponic 100% Hemp Felt Growing Mats
These 100% hemp mats are a clean and easy way to grow microgreens or wheatgrass without soil. Made from natural fibres and free from chemicals, they help create strong, healthy roots by holding just the right amount of water and air.
- Made from all-natural, sustainable hemp fibres.
- No herbicides, pesticides, or synthetic fertilisers used.
- OMRI listed and fully compostable after use.
- Pre-cut and ready to use—no soaking or treatment required.
- Lightweight and easy to handle for home or small-scale growers.
- 750 gsm thickness for strength and moisture balance.
- Size: 33 cm x 22 cm.
- Each 33 × 22 cm mat can be cut to fit smaller growing trays, including two 5 × 5 inch (12.7 × 12.7 cm) trays.
Please note: These mats are single-use only. The fine roots of microgreens and wheatgrass become embedded in the hemp and cannot be separated after harvest.
How to Use Hemp Growing Mats
Dip the mat briefly in cool water or spray it with a light mist. Let excess water drain away. Lay the mat flat in your growing tray. Evenly spread your microgreen or wheatgrass seeds on top. Cover and leave in a dark, well-ventilated spot for 2–3 days to germinate.
Once seeds sprout, move the tray to a well-lit area. Keep the mat moist but never soaked—avoid pooling water or water levels above the surface of the mat.
