Pre Mixed Mushroom Substrate Bags

Our pre-mixed mushroom substrate bags offer an effortless, ready-to-use solution that saves time and makes growing mushrooms accessible even for beginners and busy individuals.  These bags contain a premium blend of Australian-grown hardwood, either non-GMO soy hull pellets or organic wheat bran and gypsum.  These are specially crafted for mushroom cultivation and are based on the same blends we use in our mushroom farm.

Ingredient Details

Pre Mix Bags are available in three blends:

• 65% hardwood / 30% soy hull / 5% gypsum.  This is a modified Master's Mix best for heat pasteurisation AKA adding boiling water. 
• 45% hardwood / 50% soy hull / 5% gypsum.  This is the famous Master's Mix though requires either steam sterilisation or autoclave sterilisation.
• 80% hardwood / 15% organic wheat bran / 5% gypsum.  A blend ideally suited for Shiitake/Reishi/Turkey tail.  Ideally requires steam sterilisation though success can be had with just heat pasteurisation. 

You can choose between quantities of 2, 5 or 10 bags or mix up depending on your needs.  Higher quantity packs are discounted.

Made from pure hardwood and non GMO soy or organic wheat bran, with no glues, fillers, chemicals or additives.

Usage Instructions:

Depending on your skill level or requirements you can either just add 1400mL hot water and seal the bag for heat pasteurisation for a couple hours or longer otherwise add 1400mL of warm water to help the pellets expand quickly and then steam sterilise or even use a autoclave for complete sterilisation.

Hint, for heat pasteurisation use a towel or a insulated container to keep the heat up in the bag. Sealing the bag either by folding over the end of the bag a few times or using some from of clip to contain the steam can help as well.

Once the substrate has cooled to 30C or less then add the mushroom spawn between 2% - 10% (200g of mushroom spawn per bag is highly recommended if the  heat pasteurisation technique has been used) and seal the bag up.  Once incubation is complete you can fruit the bag and expect good results.

Expected Results:

Each bag should produce between 350 - 500g of mushrooms depending on whether heat pasteurisation or steam sterilisation has been used.  This will also depend on the health of the mushroom spawn and the fruiting conditions.  Ideally a dedicated space such as a Martha tent or shotgun chamber at a minimum should be used to control humidity and CO2/O2 exchange to ensure maximum fruiting production.
