This pack includes 10kg of the best sterilised organic rye grain, properly rinsed, soaked, briefly boiled and then sterilised, packed in heat-sealed unicorn mushroom spawn bags (with 0.2 micron't' filters) and injection ports added after sterilisation for convenience and ease of use. Although we quote 10kg, we always add a small amount extra toeach bag, to ensure nobody gets less than they pay for.
Rye is a member of the wheat family (triticeae) and is also closely related to barley but all that really matters to us (and probably you) is that it's an excellent choice for producing grain spawn rye can be used to produce grain spawn for the majority of mushroom species, so whatever you're growing, this is perfect for you. All our grain and substrate packs are prepared strictly to order, to assure absolute freshness. To inoculate these grain bags, simply use your liquid culture syringe to inject your live mycelium into the grain via the injection port. It's best practice to sterilise both the syringe needle and also the injection port prior to use, and then to cover the injection port with a strip of micropore tape once you're finished.
Spore syringes can be used to inoculate grain but unless it's your only option we'd always recommend that you don't, due to the much higher risk of contaminants coming from spore syringes. Some people only use spore syringes and have zero problems, but not everybody is so lucky. As all bags are made to order no more than 48 hours prior to dispatch, contamination cannot occur unless the bags are spilt in transit - in which case please send us a photograph of the bag showing both the production label and where the bag has split and a replacement will be dispatched without delay. This item is made of organic rye grain and unicorn mushroom spawn bags.
