Caution: Growing Oyster Mushrooms may increase your wellbeing

So what are the steps I need to follow?

1. Tear out the grow window and cut a cross (X) in the mushroom bag to the edges of the window space.

2. Fill the included spray bottle with water. Throughout the growing process avoid touching the plastic with your hands. Do 15 sprays at 20cm away from the grow window, at least twice a day. Keeping the plastic flaps attached and near the mushroom surface increases humidity which mushrooms love.

3. Keep your box up-right, standing tall in a light room and out of direct sunlight. Your kitchen bench is the perfect place! Your first mushrooms can pop up and say hello between 10-30 days.

4. It’s harvest time when your mushrooms stop doubling in size everyday and before your mushroom caps unfold and invert. Twist all of your mushrooms out by their roots. Make sure all mushroom remains are removed to let the next mushroom crop grow!

5. To produce your second crop, rest box for one week after 1st harvest then repeat step 2. For the 3rd crop again rest for one week before using the other side. Patience is required for crops 2 & 3.


How difficult is it to grow oyster mushrooms?

It’s very easy.. all you need to do is simply spray, harvest, eat and repeat. These Mushroom Grow Kit’s are designed to be easy.

What temperature is best for growing my mushrooms?

The ideal temperature for the best quality of mushrooms to form is between 18-24 degrees Celsius.

Where should I grow my mushrooms?

All you need to do is find an indoor space that will get fresh air and a good amount of light, so close to a window but not in direct sunlight. By placing the grow kit indirect sunlight will help the mushroom caps develop to their full potential. As soon as you see the tiny pinheads pop out, they’ll double in size each day as long as you are generous with your watering.

How do I know when it's time to harvest?

As soon as you notice that your mushrooms aren’t doubling in size each day, you can pick off the entire crop. A brown ring around the edge of the mushroom cap is key indicator that your mushrooms are ready to harvest!

How long can I store the mushrooms for?

We recommend to pick and eat them straight away however they can be stored in the fridge for 5-7 days. If you notice the mushrooms start to dry out somewhat, using them in a curry or other liquid will re-hydrate them. Did you know gourmet mushrooms are rarely found in grocery stores because they’re extremely delicate and have a relatively short shelf-life? So it makes sense to grow your mushrooms at home

How many mushrooms can I grow?

Each crop varies in size but you can grow at least 2 crops from one box.

How do I best store my mushrooms?

It is best to store them in a paper bag in the refrigerator. In the paper bag their excess moisture is absorbed by the bag, keeping it off your mushrooms but close enough to retain some moisture!

My second crop hasn't come through - What am I doing wrong?

Don’t worry. Patience is key! Each subsequent crop will take several weeks to begin growing. Regular moisture is the key.

I'm going away for a few days, will my grow kit be fine?

Ideally you should water daily, but if you are going to be away, place your box in a naturally damp or humid spot whilst you’re gone. A good example is right next to the sink and away from heat sources. Another suggestion is you could place the box on a little stand in a tray of water and as the water evaporates it will keep the environment around the kit nice and humid.

What should I do with my bag once finished?

Oyster mushroom substrate is packed with nutrients so it makes for a very valuable soil amendment. Be sure to empty the bags contents onto your favourite fruit tree or plant in the garden and watch it take off.

How long can I store my grow kit before using it?

You can store your kit for up to 3 months after you’ve received it. Store it in a dark spot at room temperature (10-20C), and then continue as per the instructions in the box.

What benefits do Oyster Mushrooms provide?

Oyster mushrooms are extremely healthy given that one-third of their dry weight is protein. They are rich in vitamin B vitamins, calcium, phosphorous and iron. This is why they are commonly referred to as the vegetarian steak.

What's the white stuff inside the bag?

This white layer is the mycelium, or ‘mushroom roots’. It has grown across and throughout the coffee grounds 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 delicious Oyster Mushrooms when the bag is opened.
