Harris Seeds Terrafibre Hemp Grow Mat

No, these mats are designed for single-use applications. Because the root systems of microgreens and sprouts become deeply embedded in the fibers, the mats are best composted after harvest rather than reused.

For most short-cycle crops like microgreens and wheatgrass, the seeds contain enough stored energy to reach harvest without added nutrients. If you are growing crops with a longer cycle, you can add a mild, hydroponic-safe liquid fertilizer to your misting water, but it is generally not required.

Mold is usually caused by overwatering or poor air circulation. Ensure your trays have adequate drainage, avoid soaking the mat to the point of pooling water, and use a small fan to keep air moving across the surface of your seedlings.

Yes, the roll is 10 inches wide, which perfectly matches the width of standard 10x20 inch trays. You can simply unroll the mat and cut it to the 20-inch length required for a standard tray.

Yes, the hemp fiber is naturally pH-neutral, which makes it an excellent, stable environment for germination. You do not need to worry about the mat altering the pH balance of your water or affecting the nutrient uptake of your seeds.
