FB33 is one of the many solutions that ITALSPAWN continues to provide to its increasingly demanding clientele.
We are now offering this new variety as a cream-type mushroom. Its main feature is that it adapts easily to any type of compost while maintaining its individual characteristics, such as its dark-brown colour. Mushroom size and high yield are maintained while complying with the usual requirements for composting and cultivation. This strain is most suitable for brown mushroom production. Its umbrella shape gives it its characteristic "PORTABELLA" American name.
