The Grey Oyster mushroom (Pleurotus Ostreatus) is one of the best and easiest mushrooms for home cultivators to grow. This strain is also referred to as the blue oyster as it sometimes has a blue hue, but this is just marketing. The blue is slight and not always apparent, depending on the light it receives. This is a low spore variety, so it does not release nearly as mush spores as normal varieties.

From 1 January 2021, in order to export live mycelium to the EU, including all
gourmet mushroom spawn, we have to acquire UK government issued
phytosanitary certificates for each batch of product shipped. This is
well beyond the scope of our resources. So we will be restricting the sale of products to overseas markets and are in the process of launching a new website and business dedicated to the our customers overseas.
