Our pre-steralised 1.5kg organic rye grain is perfect for anywone looking experiment and push their cultivation to the next level but dont have a sterile environment to hand. We use Unicorn 4T bags, complete with injection port so you can simply inject the liquid culture / spore syringe of choice and place somwhere warm and dark to colonise.


Once fully colinised you will have 1kg of high quaity grain spawn at your disposal. Either grow your mushrooms directly out, exspand it further onto bulk aditional substrates or combine/case with pasturised coir/vermiculite to see an increase in your total yield.


Steralised @ 121C for 4 hours, Double bagged within our lab and suplied with single use sterile wipes to help your projects get off to the best start.
