All nutrition comes from the hardwood sawdust substrate. Use a quality grain spawn and supplemented sawdust block for best yields. Cleanliness matters more than feeding.

Succession Growing

Start new batch every 3 weeks

Start a new block every 3 weeks. Lion's mane typically fruits once or twice per block before exhaustion — staggered starts give you a steady harvest of fresh heads.

Common questions

Lion's mane prefers 60–70°F during fruiting — cooler than oyster mushrooms. High humidity (85–95%) is critical. Low humidity causes browning and poor development.
Browning is almost always caused by low humidity or high CO2. Mist more frequently and fan the block briefly twice a day to exchange fresh air.
Harvest when the pom-pom is fully developed but before it starts to yellow. Left too long, it becomes bitter. Each block typically gives 1–2 good flushes.
