4kg Grey Oyster mushroom grow kit: ready for you to produce mushrooms (fruit), harvest and eat!


The Grey Oyster aka Pheonix Oyster (Pleurotus pulmonarius) mushroom is super-easy to grow year round anywhere in NZ - and best for overall best yield. The kit will arrive ready to produce mushrooms almost right away. We guarantee at least one harvest, but you can definitely try for up to four or more!


Kits are a living product, fully colonised with the Grey Oyster (Pleurotus pulmonarius) mushroom culture when you receive it i.e. it will be ready or close to producing mushrooms.


There are many factors that affect the kit's total yield so we can't provide an exact estimate on that. However, we will provide detailed instructions on how to get the best results without specialized equipment.


Our 4kg oyster kits are best for singles and couples (a few meals per flush) while our >> 6kg grey oyster kits are ideal for the family or sharing! 



Always identify any mushroom before consuming!

"Excellent service!

Sporeshift have consistently got the best service of any online provider I have used. From the time of order to delivery the communication is great. I frequently wonder why other businesses can't to it the way they do. Excellence in action. And no, I am not their mother ... just a satisfied customer and mushroom lover. :)"

"Loving watching the magic of the growth cycle and increasing our own food security and self reliance in the process! My kindy wildlings are loving the video updates of how they're going each day! Excited to extend my varieties next. Oysters were definitely a winner on a magenta spreen, thyme, white sauce and olive pizza tonight!!"
