From £1.89

Designed to fit inside 1020 seed trays, our Hemp Grow Mats are simply perfect for keeping your microgreens or cress fresh all year round. Easily cut to size with scissors, our hemp grow mats are 100% natural, compostable and biodegradable. Available individually or in packs of 3 or 6, this low-maintenance growing medium encourages easy root penetration for the perfect homegrown greens.


Grow Sow Greener's natural Hemp Fibre Microgreen Growing Mats are by far the simplest and cleanest method to keep your green fresh all year round.

With hemp grow mats, microgreens, cress and cut-and-come-again salads are grown quickly and easily indoors, without the mess. Simply scatter organic microgreen seeds evenly over the surface, keep moist and you will be harvesting your first greens in as little as 7-14 days. Simple as that! Read our microgreen growing guide for more detailed instructions.

Designed to fit into our Wooden Seed Trays, these Hemp Growing Mats measure 33 x 19cm and will also fit any standard sized UK propriety seed trays. You can easily cut them to suit any plate, dish or saucer you may wish to use.

Growing indoors is the perfect way to keep your nutritious, living greens year-round whilst avoiding plastics, pesticides and the supermarket. All from the comfort of your own home.

Sustainably composed of 100% natural fibres derived from the hemp and kenaf plants, these mats are produced without additives, chemicals, binders or GMOs. Their unique composition and open structure allow for easy root penetration and good access to oxygen. Hemp fibres naturally hold up to 1050% of their weight in water, which makes them lower maintenance grow medium than our coco coir mats for the busy home grower.

As a bonus, our Hemp Grow Mats naturally provide phosphate (P205) 104mg/l, potassium (K20) 694mg/l and boron (B) 0.21mg/l as plant-available soluble nutrients.

Grow Sow Greener's Hemp Grow Mats are 1200gsm weight (10mm) and will successfully support any microgreen variety*. We don’t offer for sale the thinner mats available elsewhere.

All microgreen mats are easily cut with kitchen scissors and are 100% natural, biodegradable and compostable. They are the easiest and cleanest method to grow microgreens, cress and cut-and-come-again salads and are of the highest quality. As always, our packaging is 100% recyclable and plastic-free.

*We get better results growing beets, peas and sunflowers on coco soil.

Excellent Product at Competitive Price

This grow mat is exactly as advertised. and it was dispatched quickly. I am looking forward to growing my micro greens on this matting. It’s definitely worth buying and is not anywhere near as expensive as some other sellers have priced it. I did wonder if it meant that the quality was inferior but it’s absolutely fine. Highly recommended.
