Shiitake Mushroom Grain Spawn - UK

£35

The Shiitake mushroom produces meaty fruitbodies which are highly prized for their amazing umami flavour

This 3782 Shiitake strain is aggressive and can been grown on pasteurised straw substrate as well as sterilised wood-based substrates.

It has an 8-12 week incubation period and is more challenging to grow than other mushroom varieties like Oysters, however the challenge of learning to grow them is well worth it.

This spawn pack includes:

  • 2.8kg of quality Shiitake mushroom grain spawn
  • 20 x Mushroom cultivation bags (can hold 1.5-2 kg substrate per bag)

Difficulty: Medium - Advanced

Shiitake is best suited to growers who have a bit of experience. The mycelium is slower growing and the incubation phase is much longer than most varieties, taking 8-12 weeks.

A 'popcorning' and 'browning' process needs to take place before the fruitbodies develop.

Check out our guide on How To Grow Shiitake Mushrooms for more info.
