Hardwood Briquettes / RUF Blocks

£11.00 inc. VAT

RUF oak briquettes are an integral component to many custom substrate mixes we sell, which we mix with hardwood sawdust and other supplements to create an ideal food source for mycelial growth.

Sawdust alone tends to compact, restricting air exchange for the mycelium, which can lead to slower colonisation, higher contamination risks, and lower yields. However, when soaked for 12-24 hours, these hardwood blocks swell and disintegrate, enhancing the consistency of any substrate mix they are added to, particularly for varieties that thrive on wood substrates.

EcoBlaze RUF Briquettes, often referred to as Heat Logs, Heat Blocks, or simply RUF blocks, serve as an excellent fuel source for wood burners, effectively replacing seasoned logs. Composed of compressed, untreated, clean, organic hardwood chips and shavings, they are a sustainable by-product of the furniture industry.

Improves substrate aeration, enhancing air exchange and colonisation time
Provides larger particle sizes for mycelium to utilise as nutrient islands
Simple to soak, making it easy to mix with dry ingredients before bagging
Lowers contamination rates
Contains less than 12% moisture

Each pack contains 12 RUF Briquettes, weighing 10kg per pack, making them a versatile and sustainable choice for both heating and mushroom cultivation.

Sven – 22 August 2019

leave them to soak overnight then add them to your substrate mix. Make sure your water content levels are correct for your substrate choice. I found that they hydrate to around 58% when soaked in cold water overnight and allowed to drain if that helps anyone out there… Peace out

Break up easily when soaked in water for a couple of hours, overnight soak fully hydrates the wood chips. Leave to drain for a few hours before bagging and steralising. Does make for a good substrate mix. Was also sent a couple of sample products to try thanks+
