Frequently asked questions
How do I spray my mushroom grow kit?
Once the hole in the bag has been cut, you need to spray the front of the box each day to stop the growing mix inside from drying out and to create the humidity that mushrooms love to grow in. Just spray the whole area where you have cut the hole, pulling back the flaps momentarily to make sure it all gets some water. Then allow the flaps to fall back into place as they will help to keep the humidity in. Aim to spray at least twice a day, giving the whole area a good soak each time (i.e. approx. 10 sprays).
Where shall I grow my Hearty Growers mushroom grow kit?
Your kit is pretty versatile – most people grow them inside on a shaded windowsill or kitchen worktop/table. Anywhere that has some indirect light, and isn’t near a radiator or wood burner will provide the conditions needed for growth. Humidity is most important wherever you position it – remember to soak the bag at the beginning of each crop and continue to spray daily to stop it drying out.
What temprature is the best for grow kit?
Oyster mushrooms are quite tolerant of temperature and will grow happily between 5-25C. The ideal temperature for the best quality of mushrooms to form is between 10-18C.
What's all the white in the grow bag?
This white layer is the mycelium, or ‘mushroom roots’. It has grown across and throughout the substrait/ fruiting block and has completely colonised it before we send it out to you. It’s this mycelium that gathers up the nutrients and uses them to produce delicous Oyster Mushrooms when the bag is opened.
What happens if my kit doesn't grow?
We have a lot of faith in our product and guarantee its success. The first step is just to give your kit a little extra time. As a living organism, your mushrooms will not always behave like clockwork – although most are ready for harvest after 14 days, some kits will take an extra week or two to start growing. Read through these FAQ’s and if you can’t work out what may be the problem, drop us an email to email@example.com with a photo and explanation of what has happened. We’ll do our best to advise and get your kit working, but in the unlikely occurrence that there is a problem with your kit, we will happily send you a new one free of charge.
When has the kit finished growing Mushrooms?
You will notice over time that the lovely fresh white bag you started with begins dry out, gets lighter and shrinks. This occurs as crops of mushrooms are extracted and the nutrients useful for growing mushrooms become depleted. Once you have had at least 2 crops from it, it’s worth trying to re-soak and get another, but if you do this and no further crops emerge after 4 weeks, then it is time to break up the mixture that is left and add this rich soil amendment to your plants!
Why are my second and thrid crops smaller than the first?
The first crop is always the biggest as it is grown at its peak with all the nutrients in the bag available. Each successive crop gets smaller as more nutrients and water are extracted from the kit. Soaking for longer periods and misting well can help to mitigate the moisture loss, but the nutrients will slowly run out, producing smaller crops over time.
Why hasn't my second crop grown yet?
The second crop can sometimes take a little longer to appear, but as long as the kit is not too dry, it will always come. After you harvest the first crop, leave your kit to rest for 2 days, then soak overnight in water and continue to spray daily. Your second crop will start to grow in around 7-14 days, but can occasionally take up to 21 days.
How do I store my freshly bought Oyster Mushrooms?
They'll stay fresh for 5-7 days if you keep them refrigerated. Ideally refrigerated between 2°C - 9°C
Do you have any recipes for cooking oyster mushrooms?
Do you supply spawn and other growing mediums?
Can I volunteer at your mushroom farm?
Brilliant, we are always looking for keen helpers, perhaps a few hours a week/fortnight/month. In exchange for your help, we will offer you some practical hands on gourmet mushroom farming sessions along with freshly harvested mushrooms and/or mushroom kits.Please contact us on firstname.lastname@example.org or via messengers on Instagram or Facebook
Will you be involved at the Banana Block, PortView Trade Centre
Portview Trade Centre in East Belfast and National Museums NI have developed plans to create ‘Banana Block’ – a banana field and a living museum at Portview, formerly the home of Strand Spinning Mill which was once the largest flax tow spinning mill in the world.
Hearty Growers are in the process of partnering up with USI to create see-through fungi fruiting chambers and hopefully move their farming operations at one of Banana Blocks retail units.
Where are you based?
We are an urban indoor vertical mushroom farm, based at Portview Trade Centre, Belfast Northern Ireland.
