NZ-Produced Wheat Grain


Wheat is a fantastic grain for making grain spawn for all common wood and dung-loving mushroom species.


Wheat grains are high in essential nutrients for mushrooms and act as packets of water and food for your mycelium to grow into your fruiting substrate. The hardy shells help prevent the grains from becoming mushy, making them easier to mix once sterilized.


Usage Instructions:

  • Mix with 1-2% >>gypsum by dry weight of the grain spawn (e.g., for 2 kg of spawn, use 20-40 grams of gypsum).
  • Soak in warm water for 12-18 hours, drain, bag into >>filter patch bags and pressure cook at 15psi for 3+ hours.
  • Alternativley grain can be boiled and then steam dried while hot instead of the longer warm water soak.


Grain is animal feed grade, so it may contain small pieces of straw, etc.

"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!!"
