The hard part is already done.
Sterilising grain and substrate is where most first grows die. We've done it for you. Your bag arrives sealed and ready — you inject a culture, seal the port, and wait. That's the whole job.
Double the substrate. Over double the harvest.
500–800g of fresh mushrooms per bag for £13 more than the Standard. On a per-gram basis it's the cheapest way to grow.
There's room to run two cultures side by side, so you can grow two species at once.
What's in the box:
- 2.3kg all-in-one grain and CVG bag, sterile and sealed
- Step-by-step illustrated guide
- 1 month of the Hypha app, free — AI grow diagnosis, courses and community
- Direct message access to us, start to finish
Grow whatever you want — any gourmet or medicinal species you can buy a culture for. The bag never changes, the culture does. Cultures are bought separately so you're never locked into one mushroom; we link the vendors we trust.
Beginner-friendly, despite the size — the process is identical to the Standard, there's just more in the bag. It's the one most people come back for, and plenty just start here.
Mushrooms or your money back.
BEYOND THE KIT
Our kits work with any type of mushroom. Select a species provided by the vendors below. 2ml of liquid culture/spores injected into your kits self-healing port is plenty to produce a full crop of fungi. The choice is yours.
GOURMET LIQUID CULTURES
Liquid cultures let you inoculate your own substrates and scale beyond grow kits.
PSILOCYBIN SPORES
For microscopy and identification purposes. Spore possession is legal in many regions for research; cultivation typically is not.
Hypha does not sell, supply, or facilitate the sale of psilocybin spores. Vendors listed independently. Cultivation of psilocybin mushrooms is illegal in most jurisdictions.
