Rice Flour, 250 Grams
Rice flour is a finely ground flour made from hulled rice and is mainly used in mushroom cultivation as a nutrient source for mycelium. The flour is a standard ingredient in the PF Tek recipe, a widely used cultivation method named after the grower who popularised the technique under the name "Psilocybe Fanaticus". In this method, rice flour is mixed with vermiculite (a mineral with good water and air retention) and water into a moist, nutrient-rich substrate in growing jars, allowing the mycelium to spread through it.
This rice flour is organic and finely milled, which helps it mix evenly through the vermiculite without clumping. The 250-gram pack is enough for several growing jars, depending on the jar and substrate ratio you use.
Use
Mix the rice flour with vermiculite in the ratio that fits your growing method and add water until you get a moist, crumbly mixture: the substrate should clump together when squeezed, but no water should run out. The classic PF Tek ratio uses roughly 2 parts vermiculite to 1 part water and 1 part rice flour. Divide the mixture over the growing jars, top it with a layer of dry vermiculite, and sterilise the jars before inoculating them, to reduce the chance of contamination with unwanted moulds or bacteria.
Storage
Store the rice flour dry, airtight and at room temperature, away from moisture. This keeps the flour usable for months.
