FAQ

We have posted the answers for you to some frequently asked questions. Have you read the answers, and do you still have some burning questions? Feel free to contact us via the contact page!

Do you still ship to the UK and how does COVID influence the shipments to the UK?2021-02-19T15:47:11+00:00

Yes, we still ship to the UK. However, due to both COVID and Brexit, some of our shipments to the UK are delayed or missing. Luckily, we noticed that the number of issues is decreasing.
With regret we have to inform you that our shipper UPS, just like all other shippers, has made a waiver for any claims during this COVID pandemic.
Unlike UPS we will support you in case your packages get lost, but unfortunately we cannot cover all costs. If your product gets lost during shipment, or if the substrate of your GIY-kit has become obsolete, we will give a 50% discount on the product price of your next order.

Can I ship my order to a country outside of the EU?2021-02-19T15:51:23+00:00

Yes, it is possible to ship your order to a non-EU country. As it is not possible to finalize such an order directly via the website, we ask you to send us an email with the products you want to order and the shipping address. We create a “Special product” for you, and you can finalize the order.
Do note that we cannot guarantee that your product arrives and that UPS, our shipper, currently does not accept claims due to COVID. Furthermore, we ask for an additional €25,- admin fee.
Feel free to send us an email with additional questions about this!

When will my order be shipped?2021-02-19T16:48:53+00:00

All orders are sent on the next Monday. So all orders placed and paid before Sunday 23:59 will be shipped the next Monday. This also applies for Express shipments.

When will my order be delivered?2021-02-19T16:49:52+00:00

We cannot give a fixed delivery date. Our experience is that 90% arrives within 3-5 days and Express shipments within 1-2 days.

What happens to my order if I’m not home during the delivery?2021-02-19T16:51:28+00:00

If you use a private address for shipping address and you’re not at home when UPS delivers, it most likely will be dropped at a UPS Access Point, so keep a eye on your email.

Will my order be shipped carbon neutral?2021-02-19T16:52:03+00:00

Yes, we ship all our orders carbon neutral via UPS.

How should I get started with my GIY Kit?2020-07-15T10:02:51+00:00

We have created an instruction video for you as well as an instruction manual. Do you still have doubts or questions after looking at the instructions and FAQ’s? Don’t hesitate to contact us!

What is the substrate material used in the GIY kits?2021-02-24T12:01:42+00:00

Our GIY kits consist of hemp and mycelium. The hemp consists of hemp waste particles of 5 to 15mm inoculated with mycelium.

I received my substrate! But how should I store it?2020-06-12T14:50:32+00:00

Mycelium grows in ambient temperatures. Before using the substrate, you want to slow down the growing process. Place the substrate in the refrigerator (1° – 7°C) and best use it within five days. Don’t place your substrate in the freezer.

My GIY mycelium substrate arrived with some water inside of the bag. Can I still use it?2021-02-24T12:01:00+00:00

Yes! The water is a result of the drop in temperature. We keep the substrate in a very cold environment, which is not conserved during the shipping. Therefore, some water is released.

Ooh no! I wasn’t able to use my substrate within five days, do I need to throw it away?2020-06-13T11:41:31+00:00

No, you don’t have to! We encourage you to do a little experiment and still use your substrate. If it’s very difficult to break up the substrate in small particles, it might be that the mycelium already started doing its job by gluing the particles together. Don’t worry, just add a little bit of water to prepare it for production.

My GIY substrate is white upon arrival. Is this normal?2020-06-12T14:37:31+00:00

During shipping, the mycelium is exposed to warmer temperatures and therefore starts its growth. The white is the mycelium that is doing its job. Sometimes the shipping takes longer, leading to more white parts in the bag of substrate.

Make sure to properly break down the substrate in small chunks to avoid air cavities when filling your mould.

What is the sculpting mix?2021-02-24T12:04:54+00:00

This sculpting mix helps you shape the substrate. It changes the substrate in a more clayish texture which helps to create new shapes.

How to use the sculpting mix?2021-02-24T12:07:15+00:00

1. Loosen your GIY substrate in a sterile environment
2. Add 30 g for every kg substrate used (measure precisely)
3. Add the sculpting mix
4. Mix thoroughly
5. Put the substrate in the shape you want

The sculpting mix has to be added when working the substrate, not after drying.
For more detailed instructions, check our instruction manual.

How long does the GIY substrate last?2020-06-12T14:38:00+00:00

You can keep the substrate refrigerated for a maximum of five days. During its storage, it loses moisture and can therefore dry out. Make sure you use it when it is still nice and ‘fresh’.

On the instruction sheet, is says to use ethanol. Are there alternatives which I can use instead?2020-06-12T14:39:12+00:00

Instead of ethanol, also iso-propylalcohol (IPA) can be used. Also detergent, normally used for dishes, utensils, cups, etc, can be used for cleaning moulds, hands, mixing bowl, etc. Rinse thoroughly so no soap is left behind.

Can I just use my normal oven?2020-06-12T14:39:41+00:00

Yes, when baking your product, you can use your own oven. Put the heat around 70° C and leave it for at least 2-3 hours.

I am not quite sure where to place my mycelium during the growing phase. Does the mycelium need to grow in the dark?2020-06-12T14:40:15+00:00

No, this is not required. Mycelium grows just fine in a dark place, and some daylight does not matter. Do not place the mycelium in direct sunlight, this will heat the substrate and it could dry out faster.

Can mushrooms grow out of the substrate? This seems like a nice extra feature for my product.2020-06-12T14:40:49+00:00

It’s possible but it’ll weaken the structure of your product. If this is not an issue for the purpose you have in mind for your product, feel free to experiment and extend the growing period. When the substrate starts to turn brown-ish, it means mushrooms are on their way!

Please keep in mind that if you need your product to be strong, you have to stop the growing process in time.

According to the instructions, I have to mix the substrate once all ingredients have been added. When is the substrate properly mixed?2020-06-12T14:41:19+00:00

Make sure to keep mixing until all flour is evenly distributed, meaning no chunks of flour in your substrate. Also, try to avoid chunks of substrate by breaking them apart in small particles with your (clean) hands or tools.

Wait, is mycelium poisonous?2020-06-13T10:40:46+00:00

Mycelium is not poisonous, but we definitely do not recommend eating the substrate.

Is mycelium waterproof?2020-06-13T10:39:18+00:00

No, the material will lose rigidity and will become susceptible to degradation when repeatedly exposing it to water. It does repulse water for some time and it even floats! Of course, it not raining all the time. In between showers the material will passively dry and maintain some rigidity. But in the long run, it will lose.

We are working on the development of a bio-based coating that makes our material 100% waterproof.

I’m looking for a sustainable packaging alternative for my product. Is my business product suitable for mycelium composites?2020-06-13T10:37:46+00:00

What are the properties of your mycelium composites?2020-12-10T20:25:39+00:00

We have summarized the properties in a spec sheet for you.

I want to experiment with my product once I received it. How can I adapt my product post-production?2020-06-13T10:35:59+00:00

The possibilities are endless! You can for example cut the material with a saw, drill holes in it or cover it in laminated wood. We recommend natural, biobased sealants as the purpose of the material is to not add toxins to the environment. The material can be sanded and finished with beeswax, milk paint, water-based polyurethane, and more.

I want to use my mycelium cool box to keep my food cooled. But are your materials suitable for food or beverage containers?2020-06-13T10:35:06+00:00

Our materials are not certified for direct food contact. The materials are water permeable and are not recommended for applications such as disposable cups.

So, how long does the final mycelium material last?2020-06-13T10:26:19+00:00

It strongly depends on the environment in which you place your product. If you keep it in an inside environment, its lifespan can be a couple of years. Only when it comes into direct contact with soil or water it will start to degrade. Do not expose to high humidity.
