Ownership. Red Light Holland bought 80% of Happy Caps in June 2021, and it now runs as a Red Light Holland subsidiary still selling grow kits with a subscribe-and-save option.

What's in the box: A ready to grow block for shiitake, lion's mane or oyster mushrooms, with growing instructions for each species on the site.

Happy Caps is a Canadian company that makes indoor mushroom grow kits. It has run as a subsidiary of Red Light Holland since that company bought an 80% stake in 2021. The range is small: shiitake, lion's mane and oyster kits, each sold on its own, plus a multi-kit deal at checkout. The site also sells mushroom gummies, and that is where the subscribe and save option appears. The site does not make clear whether you can get grow kits on a recurring delivery. In practice it is a kit shop with a subscription add-on, not a true subscription box.

The kits are aimed at beginners. Each species has its own growing instructions page, which helps if this is your first time growing mushrooms at home. Happy Caps also sells through Costco, Real Canadian Superstore, Canadian Tire, Amazon and Longo's, so you can often buy a kit in person and skip shipping.

The site does not say how often subscription orders ship, how to pause or cancel, or what happens if a kit fails to produce mushrooms. The range is also narrow, so experienced growers who want rarer species or growing supplies will outgrow it quickly. For a simple, low commitment way to start growing gourmet mushrooms in a Canadian kitchen, it is a reasonable choice.
