Hardwood sawdust blocks made from Oak that has been heat treated and compressed. Perfect for growing many types of mushrooms in.  Pasteurise with hydrated lime or wood ash or for best results heat treat.

Simply mix desired amount of Oak pellets with the correct amount of spawn (10-25% of the straw weight in spawn) and rehydrate with water (2.2 times the kilo weight of the substrate in litres). So if you had 10 kilos of Oak you would multiply that by 2.2 making 22 which would mean you need 22 litres of water to rehydrate the 10 kilo Oak block effectively. 

This Oak sawdust is great for growing Shiitake! You can also mix it with the straw pellets to grow some amazing Oyster and Shiitake mushrooms as well as many other species.

The smallest increment we stock is 2.5-3kg of Oak sawdust which comes in 6 compacted blocks which when filled with spawn and fruited could yield up to 250grams of mushroom per kilo of wood dependent on species grown.
