How long until mushrooms appear?

Button mushrooms colonize and pin more slowly than oyster kits. Expect the first pins in a couple of weeks and harvestable caps after that, depending on room temperature. Follow the included instructions and keep the block out of direct sunlight.

Where should I put the kit?

Any counter or table indoors at 60-68°F, out of direct sunlight. Cooler rooms fruit better; a warm kitchen slows or stalls button mushrooms.

How do white button mushrooms differ from cremini and portobello?

They are the same species, Agaricus bisporus, picked at different stages. White buttons are the youngest, cremini are older, and portobellos are fully mature.

A colonized growing medium block, a casing layer, and detailed instructions. No spores or separate spawn are needed.

Can I get more than one harvest?

Button mushrooms typically flush more than once. Keep the block cool and follow the instructions between flushes, then compost it when it stops producing.

Our take on the White Button Mushroom Growing Kit

This is an indoor grow kit for white button mushrooms (Agaricus bisporus), the same species as cremini and portobello. It ships as a colonized medium block with a casing layer and instructions; you set it on a counter out of direct sunlight at 60-68°F and harvest in flushes. White button kits are less common than oyster and lion's mane kits, which fruit faster and more forgivingly; button mushrooms want cooler room temperatures and a casing layer, so they reward patience more than speed. It suits families and first-time growers who want the familiar supermarket mushroom and a project that runs over weeks rather than days.
