Nublume makes two kinds of mushroom grow kits. BloomBox is pre-inoculated, so it is already growing when it arrives: you open it, spray, and harvest. ShroomBloom is an all-in-one inject-and-grow kit: you add your own mushroom culture to a bag of sterilized grain and substrate and grow bigger harvests. This page shows how they differ so you can pick the right one.
The short answer
Choose BloomBox if you want a ready-to-grow kit for gourmet cooking, a first grow, a family project or a gift. Choose ShroomBloom if you want to pick your own culture, including exotic species, and grow larger flushes.
