Celtic mushrooms is an innovative enterprise that was developed with the inspiration to run sustainable projects that have a positive impact on local issues and needs, waste recycling and green living.We are using agricultural (straw) and catering (coffee grounds) waste as a substrate to grow nutrient rich exotic mushrooms. Celtic Mushrooms Company has created an optimum environment for propagating mushrooms. We produce mushroom spawn (mycelium) of Oyster (winter grey, pearl, pink, golden and king) and Shiitake mushrooms using our unique method. Also we developed Grow-your-own Eco-friendly mushrooms growing kit that will allow anyone to easily grow and enjoy exotic mushrooms all year round at home. All that is required to grow mushrooms from our high grade mycelium is a windowsill. To grow mushrooms at home is a fun and unique experience to grow your own delicious and healthy food without the need for much space or time.
