ComposTex Compost Cover (compost fleece) is a breathable, UV-resistant fabric designed to protect compost piles and windrows while still allowing oxygen flow for healthy decomposition. It sheds rain and snow melt while maintaining ideal aerobic conditions.
At KoruKai Herb Farm, we also use it for simple, low-tech worm farming systems directly on the ground.
Available sizes (please choose below): 1.20m x 1.20m 1.20m x 2.40m 1.20m x 3.66m
For different sizes, large quantities or a whole 50m roll (3.66m width) please send an email to Kai at [email protected] for a quote. We can supply any length required.

ComposTex Compost Covers—also known as compost fleece—are a high-performance, breathable, non-woven fabric made from 100% UV-resistant polypropylene. Designed specifically for composting systems, this material provides an ideal balance of protection and airflow, making it an essential tool for managing compost piles and windrows in all weather conditions.
Unlike fully sealed covers that can suffocate compost and create anaerobic conditions, ComposTex allows oxygen to pass through the fabric while effectively shedding excess rainfall and snow melt. This helps maintain optimal moisture levels inside the pile, supporting strong microbial activity and efficient decomposition.
By protecting compost from becoming waterlogged while still allowing it to breathe, this cover helps create more consistent, faster, and higher-quality compost. It also reduces nutrient leaching and prevents piles from drying out too quickly in exposed conditions.
At KoruKai Herb Farm, we also use this material as part of a fast, simple, and low-tech worm farming system set directly on the ground—demonstrating its versatility beyond traditional composting applications.
They make an amazing low-tech worm farm. Please see video below.
The 1.20m x 3.66m makes a fantastic worm farm to shed water and let air through.

A durable, breathable compost cover designed to balance protection from the elements with the airflow required for active, healthy composting systems.
Works well. Insulates and keeps the rain out while still letting air in, just as described. Toasty warm. Buying a second one. Thanks.

Compost Cover
I bought this cover from KoruKai last year after watching Cornelias video of her on ground worm farm. I have a worm tower with average results so I wanted to give this a go. The cover is just great, it keeps my worm farm dry even in super wet Auckland plus I use it to cure my compost when I take it out of the compost bin. I even experimented with growing kumara earlier this year by putting a whole kumara under the cover in the worm farm and had amazing results for a first time kumara grower!

A compost thermometer is an essential tool for successful hot composting and worm farming, whether in a home garden or commercial setup.
It provides a clear indication of microbial activity inside your compost pile, helping you determine when to turn it and whether your carbon-to-nitrogen balance is working correctly. Temperature readings quickly show if your mix contains too many “greens” (too hot), too many “browns” (too cold), or insufficient moisture (low microbial activity).
Without temperature monitoring, composting becomes guesswork—this tool allows you to refine your process and consistently produce high-quality compost over time.
Made from stainless steel with a long probe designed to reach deep into compost piles and soil.
Heavy-duty TeaLAB extract bag made from 400 micron nylon mesh and climbing-grade binding, designed for making high-quality compost and vermicast extracts. Durable, reusable, and built to last.
A robust, reusable extraction tool designed for serious gardeners, growers, and soil biology enthusiasts.
Perfect for use in compost extract or tea brewers with included carabiner clip for easy suspension.
Available in two sizes:
Small (23 × 36 cm) – makes approx. 20L
Large (51 × 56 cm) – makes approx. 60–200L (or more in staged batches)
The TeaLAB Extract Bag is made out of 400 micron nylon mesh and climbing grade binding. Hand stitched in Seattle USA by a cut and sew shop that specializes in hard-core backpacking gear, needless to say, this bag is made to last.
This bag is great to make your own compost and vermicast extract. You can also suspend the bag in a compost tea brewer with the carabiner clip.
Sizes (please choose below):
Small Extract Bag: 23 cm x 36 cm to make 20 litres of compost extract or tea
Large Extract Bag: 51 cm x 56 cm to make 60-200 litres of compost extract or tea. For larger amounts like 1000 litres simply add fresh compost to the bag 3-5 times, dilute and add to your brewer.

A compost thermometer is a necessary piece of equipment for hot composting and worm farming in a home garden setting and for commercial operators.
It gives you an indication of the microbial activity, telling you when it needs to get turned and indicates if your carbon and nitrogen ratio of your compost materials were adequate. By measuring the temperature you will see if you have added too much green material (gone too hot) or not enough (too cold) and if your moisture level was adequate (not enough moisture, no microbial activity). Without a thermometer you are merely guessing and you cannot improve this valuable skill as a home or commercial gardener.

This cover crop seeds or green manure seeds mix has been blended to achieve maximum benefit. It can help with common challenges such as compaction, weed pressure, pests and diseases, low fertility, leaching and erosion.
Best sown between August/September and December/January, depending on your climate.
This diverse mix maintains living soil cover in areas that would otherwise be bare. This mix contains seeds from 8 plant families as well as legumes (nitrogen fixing plants), which has been proven in field trials to be very beneficial to build soil structure and to increase beneficial microbes in the soil.

Your worms are shipped on the date stated above. This gets also printed on your invoice.
Composting worms transform food and garden waste into rich compost and fertiliser to regenerate soil and bring back life force to the below ground livestock - the microbes. This turns on nutrient cycling, grows resilient and healthy plants and increases the water holding capacity of soil - a necessity with droughts and flooding that go hand in hand nowadays.
You will receive 250g of composting worms (approx. 1000 worms) or 500g (approx. 2000) with some moist bedding in a perforated bag. The worms come in all ages and sizes, breed and grow fast.
This amazing guide brings together what we have learnt, observed and experienced over the last 12 years of managing several worm farms to get amazing worm castings for our farm and vegetable gardens.
In this guide, with 70 pages, you will learn how to turn food scraps and farm waste into rich compost and fertiliser to regenerate soil and bring back life force to the below ground livestock - the microbes. This turns on nutrient cycling, grows resilient and healthy plants and increases the water holding capacity of soil - a necessity with droughts and flooding that go hand in hand nowadays.
Healthy soil is the backbone of health - be it environmental, animal, plant or human health. It's our foundation and the solution to a lot of our problems.
