All In One Mushroom Substrate Bags - 1.4KG Finish Weight

Each bag should produce between 200 - 300g first flush 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.

Give your mushrooms the best start with our all in one mushroom fruiting bags.

Depending on your skill level or requirements you can either just add 750mL boiling hot water and seal the bag for heat pasteurisation for a couple hours or longer otherwise add 750mL of warm water to help the pellets expand quickly and then steam sterilise or even use a autoclave for complete sterilisation.

Hint, for boiling water heat pasteurisation use a towel or a insulated container to keep the heat longer 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, add the mushroom spawn between 2% - 10% (100g 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.

These bags are available in four different blends depending on which species your growing or your level of sterilisation available:

- 50% hardwood / 45% soy hull / 5% gypsum. This is the famous Master's Mix or Fast Fruiting Mix though requires either steam sterilisation or autoclave sterilisation.
- 65% hardwood / 30% soy hull / 5% gypsum. This is a modified Master's Mix best for heat pasteurisation AKA adding boiling water straight into the grow bag.
- 80% hardwood / 15% organic wheat bran / 5% gypsum. A blend ideally suited for Beech, Reishi, Shiitake, and Turkey tail. Ideally requires steam sterilisation though success can be had with just heat pasteurisation.
- PF Tek Classic Ratio of 2:1:1 Vermiculite:Organic Brown Rice Flour:Water with 5% Gypsum.

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