520

520 gives consistent production in terms of weight and quality. The spontaneous pin set and rapid development produce sufficient stem length, guaranteeing an even crop and good harvest. 520 is suitable for the production of both small and large processed mushrooms. 520 is more aggressive than 512 during ‘case run’, pin set and pin development. 

512 & 520 are particularly suited to mechanical harvesting. They are tolerant of changing compost and growing conditions and give consistent production in terms of both weight and quality. These strains are easy to pin so mycelial growth must be controlled with a wet, heavy and coarse casing layer. To further control casing colonisation, casing with a controlled watering regime during case running must be used.
