Grow Blocks

Grow mushrooms at home with Harmonix ready-to-fruit grow blocks. Each bag is a fully colonized organic hardwood block — one species, already living, ready to fruit when you cut an opening and mist it.

Shop oyster mushroom grow kits (blue, Italian, Winter White, Trail of Tears), lion's mane, reishi, shiitake, king trumpet, pioppino, tiger sawgill, and more. Kitchen mushrooms you sauté. Tea mushrooms you dry and simmer. No blend and no powder: the name on the page is the mushroom in the bag.

Most culinary blocks pin in about 1–3 weeks. Slow tea species take longer; those product pages say so. Free shipping on orders $150+.
