Haxnicks Microgreens Growing Mats provide a natural, soil-free growing medium for cultivating fresh microgreens at home, in greenhouses and in small-scale propagation environments. Made from hemp fibre bonded with natural latex, these biodegradable mats offer a practical alternative to conventional compost-based growing methods.

Measuring 33 x 18cm, the mats are designed to fit Haxnicks Bamboo Seed Trays and can also be used with many other compatible growing trays. They can be trimmed to size, making them suitable for different propagation setups and smaller growing containers.

Microgreens are young edible seedlings harvested shortly after germination. Growing them on a natural fibre mat provides a clean, convenient way to produce fresh greens without handling bags of compost or filling traditional seed trays with growing media.

The hemp fibres provide a surface for seeds to germinate and developing roots to establish. With appropriate moisture, light and growing conditions, the mats can support the production of a wide variety of suitable microgreen crops.

Natural hemp fibre growing medium

Haxnicks Microgreens Growing Mats are manufactured from hemp fibre with natural latex used to bind the fibres together.

The fibrous structure provides a growing surface that can be moistened before sowing. As seeds germinate, their roots develop into the mat, helping to hold the young plants in place during growth.

Unlike loose compost, a fibre mat does not need to be measured out or spread across a tray before every sowing. This can simplify preparation and reduce the amount of loose growing medium handled during propagation.

The mats are biodegradable and compostable, providing an alternative to synthetic propagation mats. After harvesting, the used mat and remaining root material can be composted where suitable composting facilities are available.

Material note: The mats contain hemp fibre and natural latex. They should not be described as being made entirely from hemp fibre.

How to grow microgreens using hemp mats

1. Prepare the growing tray

Place a growing mat inside a clean, suitable seed tray. The Haxnicks Bamboo Seed Tray is designed to accommodate the mat, although other appropriately sized trays can also be used.

If necessary, trim the mat with scissors to fit the tray.

2. Moisten the mat

Thoroughly moisten the mat with clean water before sowing. The fibres should be evenly damp to provide suitable moisture for germination.

Avoid leaving excessive standing water around the mat, as prolonged waterlogging can create unsuitable conditions for developing seedlings.

3. Sow the seeds

Distribute suitable microgreen seeds evenly across the surface, following the seed supplier's recommendations for sowing density and germination conditions.

Different crops require different sowing rates. Larger seeds may need more space than smaller-seeded varieties.

4. Maintain suitable growing conditions

Keep the mat consistently moist throughout germination and early growth. Provide the temperature, ventilation and lighting appropriate to the chosen crop.

Monitor moisture regularly, particularly in warm or well-ventilated environments where the mat may dry more quickly.

5. Harvest the microgreens

Once the crop reaches the appropriate harvesting stage, cut the shoots above the growing mat using clean scissors or another suitable harvesting tool.

Because the plants are grown without loose compost, harvesting can be cleaner and easier to manage.

Which microgreens can be grown on hemp mats?

Hemp growing mats can be used for many commonly cultivated microgreen varieties, provided their germination and moisture requirements are suitable for this type of growing medium.

Microgreen crop Growing considerations
Radish A popular microgreen crop with relatively rapid establishment under suitable conditions.
Broccoli Small seeds suitable for producing tender young shoots.
Mustard Useful for producing peppery-flavoured microgreens.
Rocket Produces distinctive-flavoured young leaves and requires careful moisture management.
Pea shoots Larger seeds require appropriate preparation, spacing and sufficient moisture during establishment.
Sunflower Larger seeds require suitable sowing density and careful management of moisture and airflow.

Always use seeds intended for edible sprouting or microgreen production. Not all plant species are suitable for consumption as microgreens.

Ideal for home growing & small-scale production

Microgreens Growing Mats are particularly useful where a compact, straightforward growing method is preferred.

Windowsill growing Produce small batches of fresh microgreens in a suitable tray where adequate light and growing conditions are available.
Greenhouse propagation Use in protected growing environments with appropriate temperature, ventilation and moisture management.
Microgreen trials Useful for testing different varieties, sowing densities and growing conditions in separate trays.
Small-scale production Provides a convenient growing medium for repeat microgreen sowings.
Educational growing projects Allows germination and seedling development to be observed without conventional compost.

Hemp growing mats vs traditional compost

Both natural fibre mats and conventional propagation compost can be used to grow suitable microgreen crops. The most appropriate choice depends on the crop, growing system and preferred method of cultivation.

Feature Hemp Growing Mat Propagation Compost
Preparation Place the mat in a tray and moisten before sowing. Fill the tray with a suitable depth of growing medium.
Growing medium Natural hemp fibre bonded with latex. Loose compost or other propagation substrate.
Harvesting No loose compost around the harvested shoots. Loose growing medium may require additional care during harvesting.
Tray compatibility Can be cut to fit compatible trays. Can be used in a wide range of containers.
Nutrition Primarily provides physical support and moisture; crop nutrition depends on the growing method. May provide nutrients depending on the compost formulation.

Haxnicks Microgreens Growing Mats FAQs

What are Haxnicks Microgreens Growing Mats made from?

They are made from natural hemp fibre bonded with natural latex. The combination creates a fibrous growing surface suitable for soil-free microgreen production.

Do I need compost when using these mats?

No. The mats are designed to provide a growing medium for microgreens without the need for conventional compost.

What size are the growing mats?

Each mat measures approximately 33 x 18cm and can be trimmed to fit smaller compatible growing trays.

Which trays are compatible with the mats?

They are designed to fit Haxnicks Bamboo Seed Trays and can also be used with other suitably sized growing trays.

Can I cut the growing mats to size?

Yes. The mats can be trimmed with scissors to suit smaller trays or different propagation layouts.

Do microgreens need fertiliser when grown on hemp mats?

Many microgreen crops can complete their short growing cycle using nutrients stored within the seed. However, requirements vary by species, growing duration and production method. The mat itself should not be treated as a fertiliser.

Can the mats be used more than once?

They are best treated as single-crop growing media. Roots become established within the fibres during cultivation, making it difficult to remove all plant material after harvesting.

Are the mats biodegradable and compostable?

Yes. Haxnicks identifies the hemp and natural latex mats as biodegradable and compostable.

Can I grow microgreens indoors?

Yes. The mats are suitable for indoor microgreen growing when used in an appropriate tray with sufficient light, ventilation and temperature control.

How do I prevent the growing mat from drying out?

Check moisture regularly and add clean water when required. The mat should remain appropriately moist during germination without becoming excessively waterlogged.

How do I reduce the risk of mould during propagation?

Use clean trays, suitable seeds and clean water. Avoid excessive moisture, maintain appropriate airflow and follow crop-specific growing guidance. Discard crops showing signs of spoilage or contamination.

Can I grow any type of seed as a microgreen?

No. Only grow plant species suitable for consumption at the microgreen stage. Use seeds intended for edible microgreen or sprouting production and follow the supplier's growing instructions.

What are the advantages of using a growing mat instead of compost?

Growing mats eliminate loose compost from the propagation tray, simplify preparation and provide a cleaner growing surface for harvesting young shoots.
