1 spore syringe contains several millions of spores, soluted in 10 ml of sterile water. The Elm Oyster is a deliciose edible mushroom which can be used like other Oyster Mushrooms! It produces larger fruit bodies, colored white to light grey or light brown. Growing conditions: Spawn run: 21 - 27 °C Primordia formation: 10 – 13 ° C Fruiting: 13 – 18 ° C Convenient substrate: Hardwood (most suitable: oak, beech, plum, maple, elm, birch, alder, ash), wheat straw PF-Substrate (yield: approx. 160 g fresh mushrooms from 1 jar /microbox 400 - 500 ml with vermiculite- riceflour substrate) Stored in a cool (max. 20 °C) and dark place, packed in airproof bags (zip-lock bags), spore syringes are germinable for at least 1 year from delivery. We reommend to store spore syringes not colder then 5 degrees celsius or 41 degrees fahrenheit. We produce our spore syringes from our tesed, high quality made spore prints, under sterile conditions in our laboratory. All our spore syringes are produced continuously fresh. (All about spore syringe production - please click her for detailed instructions!) Mainly for hobby mycologists the cultivation with spore syringes is well proven. Smal quantities of substrate or grain (mostly rye, colonized by a fungus wich is used for inoculaton of a fruiting-substrate) can be easily inoculatet with spore syringes. Even if you could not work ins perfect sterile athomosphere the failures by contamination will be very low. The elm oyster is relatively unambitious in growing conditions. Therefor they are suitable for beginners, to study the lifec cycle of mushrooms and learn how to cultivate them.
