2.5KG / 5LB Masters Mix Mushroom Fruiting Block

The tried and tested king of substrates, developed specifically for wood loving mushrooms. This highly supplemented substrate ensures a high-yielding first flush!

We have seen great harvests of Golden Oyster, King Oyster, Grey Oyster, Lions Mane & Shiitake using this substrate. 

We make the masters mix fruiting blocks by first mixing 50% oak hardwood sawdust and 50% soy hulls (with a couple of extra secret ingredients) and hydrating them to the correct moisture content. We then load each heavy-duty grow bag with the mix, heat seal them and sterilise at 15psi for 120 minutes in our commercial autoclave.

We take great pride in our attention to detail and techniques ensuring you will receive nothing but the best possible product.
