+ How do I start my mushroom kit?

Have a look at our short YouTube clip to see how to set up side fruiting mushroom kit.

+ Oyster Kits / Side fruiting extra flushes, do I turn my block around, cut a new X, soak in water?

  • make sure all the bits of mushrooms are picked off the substrate
  • do not put your block in the fridge, just leave it where you were fruiting it. (if you put it in the fridge it will go to sleep and leave the mushroom mycelium vulnerable to other things starting to grow on it)
  • after 2 weeks (or if mushrooms start growing again before then)  start misting again each species and depending on the temperatures will take different times to re-flush later flushes do take longer to come through so hang in there they will come when ready :)
  • Another option people like to do after the 2 weeks wrap the block up in cling wrap then cut a new x on the opposite side you fruited on last time.
  • if your block feels very light it may need a soak in cooled boiled water (or distilled) overnight
  • after 2-3 flushes it may need to soak in water to rehydrate the block, (use cooled boiled or distilled or spring water)
  • Mushrooms are mainly water so more water = more mushrooms
  • submerge the block in water for 12-24 hours, and drain all the excess water away, when you start misting again you won’t have to mist as much as the block is full of water again.
  • the record so far is 8 flushes from an oyster block can you beat it.

+ How long can I store my mushroom kit?

  • If you are not ready to fruit or use your spawn please put the bag(s) in a clean cold fridge (1-5 degrees) until you are ready. Most species are fine for 1-2 months. This will put the mushrooms to sleep.
  • OTE: Pink oysters and hot weather types need to be used immediately.
  • If you have purchased your mushroom kit or spawn as a gift. Keep it in the fridge until you are ready to give.
  • Please Note: Mushrooms are a live culture, if you don’t put them in the fridge they will grow out of the box on their own.

+ What is the white mould growing on my mushroom block?

This is called Mycelium. Mycelium is the vegetative part of a fungus or fungus-like bacterial colony, consisting of a mass of branching, thread-like hyphae. This is a good sign that your mushroom block is healthy and is what the mushrooms grow from. It can vary in colour between mushroom types. Some will appear a thick and vivid white while others will be more subtle.

  • Morchella angusticeps mycelium, as it matures turns brown and will start to look like fairy floss on top
  • Hericium coralloides mycelium looks very bare as its a very fine wispy mycelium and is hard to see with the naked eye
  • Lepista nuda mycelium is thicker and will start to grow purple when it matures
  • All mushroom spawn, if you look closely through a microscope will have a white coating around the grain, some you can see better than others.
  • All species of fungi and their mycelium are different and shouldn’t be treated the same.
  • All products we send from our facility are grown and ready to use.

+ There is a hole in my mushroom kit bag, what do I do?

This won’t affect your mushroom kit growing at all as they get cut open to fruit the mushrooms anyway.

+ My mushroom kit box is damaged, will this affect my mushroom kit?

This will not affect the growth of your mushroom kit. The box is aesthetic.

+ What is the volume of your ready to grow oyster bags?

Our ready to fruit kits are 5L blocks. They harvest between 4-8 rounds, yielding between 300-700g per round. Harvests yield less each time as the mushrooms break down the block, (which is their food source). How many harvests you get depends on the environment and how you look after the block.

+ What is the easiest mushroom to grow?

Oyster mushrooms are the easiest and most satisfying to grow. They grow in clusters, are quite meaty, and can grow quite large depending on the environment although taste better at a mid-size. The easiest way to grow them is with a ready to fruit mushroom kit. An oyster mushroom kit can have between 4-8 harvests each block, yielding from 300-700 grams per harvest. The first harvests yielding the most and then less each time as the mushrooms break down the block (which is its food source).

+ What are the best mushrooms to grow seasonally?

PLEASE NOTE: This is an indicative guide based upon averages. Actual fruiting temperatures are notes on the mushroom bag. How a  mushroom grows will depend on the environment it is in and how it is looked after by the end user.

+ When do I harvest my mushrooms?

As a rule of thumb keep an eye on the caps. They are best consumed when the edges are facing down. As soon as the edges start to curl upwards they are getting ready to seed, this is where you might find little dust spores spreading around the mushrooms. Some people are okay with spores, others may have a reaction to this. Do not consume if the mushrooms have become wilted and soggy.

+ How many harvests will I get out of a mushrooms kit?

How many harvests you get out of each block varies between the type of mushrooms, its environment, and how the end-user looks after it. Below is a rough guide based on consumer feedback:

  • Side Fruiting Mushroom kits: Approx 4-8 harvests
  • Top Fruiting Mushroom Kits: Approx 4-8 harvests
  • Shiitake Mushrooms kits: Approx 2-4 harvests
