Frequently Asked Questions


Depending on species you may get 2-4 flushes. But we guarantee at least one flush of mushrooms.

There are many factors which determine the amount of flushes. Mushrooms are a living organism and it is quite a skill to cultivate them. Humidity, fresh air and temperature are the pillars of mushroom cultivation.


Besides a hand of playing cards of the same suit. A "flush" in mushroom cultivation is each crop or harvest of mushrooms. Depending on species, they usually appear once every 7-14 days.


Most mushroom kits are token size, ours weigh between 2.2 and 2.6kg. They are what the mushroom industry calls "fruiting blocks".

That said, depending on species, first flushes usually yield 400g-1kg.

Each subsequent flush is usually smaller.


Remove your block from the plastic packaging and

Bury your block in the garden and cover with mulch or soil - this will encourage them to flush again!


Break it up and use as mulch


When there isn't enough humidity around the block, mushroom pins usually stop growing. Don't be alarmed! Your mushroom kit is still alive and can fruit. Simply remove the dried-up pins (mushrooms) and leave the block to rest for a week. After that, soak the block in cold water for 20 minutes, remove all the water from the bag, and begin again.

Winter White Oyster Mushrooms Ready For Harvest

Grow It Yourself!

You want to harvest right before the margin of the mushroom cap begins unfurling toward the sky and the mushroom becomes trumpet-shaped. If you wait a little too long, there’s no harm done! The mushrooms are still delicious. Over the next two months, you can expect another 2-3 flushes if the conditions allow!

Mushrooms growing out the side of a bag

How Do I Grow It? 

  • Step 1
  • Step 2
  • Step 3

Place your block on its side and where the block presses against the plastic, take a sharp clean knife and make a 10-12cm cut along this part of the bag (you could cut an “x” shape or a simple line). 

Place your sliced bag in a humid part of your home (near the kitchen sink or bathroom). Make sure it is kept away from direct sunlight, and keep it well hydrated. Do this by spraying the outside of your block, over the sliced area, with water at least once per day but preferably 2-3 times.

The mushrooms can take 2-6 weeks to fruit, but will usually appear within 5-7 days. Once they appear, keep watch, they grow very fast and will be ready to harvest in 7-21 days. Harvest them all at once by gently grasping the mushrooms at the base, twist and pull.

Winter white oyster mushrooms kit

Quick dispatch, clear instructions plus a tiny spray bottle included.

The first flush grew fast & plentiful and was super delicious. It has been such a delight to watch them grow!

10 out of 10 recommend.

Cannot recommend That Mushroom Guy enough. The first kit we bought last year was incredibly productive and it was a lot of fun to watch them grow. We then bought a black king oyster kit for my mum for her birthday - unfortunately that kit did not work out so well (likely due to user error). I messaged Brett who provided some great advice to try to fix the situation which we tried but alas, we were too late to save it. No problems, That Mushroom Guy (Brett) Mushroom guarantee saw him then send a replacement kit at no cost with no questions asked. We also recently grew one of their pink oyster mushroom kits which exploded with fruit and was both delightful and delicious. Overall, great mushrooms and incredibly friendly and supportive service.

Thank you so much for your glowing review! I'm thrilled you enjoyed the kits and found the growing process fun. I'm always happy to help with replacements when things don't go as planned. Your satisfaction means the world to me!

Winter White Oysters

Absolutely fantastic. I call them the Winter White Wonders. They taste delicately beautiful with a full mushroom flavour that dances in your mouth once you bite into the delicate white wonders of the oyster mushroom.
I had never grown them before and true to note did exactly what the instructions said. Thank you we are still getting the first wonderful wonders and eating this delicacy. Perfect.

Hi there! Thank you so much for your lovely review of our Winter White Oyster Mushroom Grow Kit. We're thrilled to hear that you had a fantastic experience growing and enjoying these delicate white wonders. We take pride in providing clear and accurate instructions, so we're glad to hear they were helpful. Happy mushroom harvesting!


Love it

Thanks for your review!


I have now been advised that
It maybe that I had no mushrooms produced and contamination due to the mushrooms SPAWN bag being different to a mushroom kit that iv used before.

Yes, unfortunately, mushroom spawn cannot be used in the same way as a mushroom kit. Our kits are specifically designed for easy and successful cultivation, while using spawn requires more specialized knowledge and techniques. We apologize for any confusion this may have caused.

Thank you for choosing our product and we hope to have the opportunity to provide you with a better experience in the future.
