Every kit here is ready growing, hand-planted in small batches on our family farm in Storrington, West Sussex. The range runs from fast, forgiving oyster kits for a first grow, through gourmet king oyster, shiitake and lion's mane, to outdoor log kits that crop for years. Each kit arrives already colonised, so there are no spores, no inoculation and no sterile setup. You choose a variety, spray it daily, and pick fresh mushrooms within days of the first crop showing. This is the growing-kit catalogue, the page to use when you want to compare varieties and pick the right one to grow. If you just want the quickest route to buy or gift a kit, buy a kit covers that side.
How the kits work
+A growing kit is compost or a log that has already been run through with mushroom mycelium at the farm. The slow, risky colonisation stage is done, so all that is left is to trigger fruiting with light, fresh air and moisture. The exact method depends on the variety, and there are three across the range.
Oyster kits (growing holes)
Pink, white, black pearl and other oyster varieties fruit through pre-cut holes in the side of the box. You mist through the holes twice a day and clusters push out within a few days.
Log and casing kits
King oyster and the chestnut and white button kits fruit from the top, under a thin layer of casing soil that you keep damp. The mushrooms come up through the surface.
Specialist and outdoor kits
Lion's mane, shiitake and enoki grow indoors from a colonised block, while the outdoor log kits are inoculated hardwood you keep in the garden for repeat harvests over several years.
Whichever method a variety uses, the daily job is the same: keep it damp and let it breathe. Our guide on how much water each kit needs sets out misting by variety.
The varieties
+Oyster mushrooms
The oyster family is where most people start, because the kits are fast and forgiving. Pink oyster is the warm-home specialist, coral coloured and quick. White oyster is the reliable all-rounder at normal room temperature. Black pearl oyster brings dark, ruffled caps and thick, meaty stems. King oyster is the meaty one, grown for thick stems that sear into vegan scallops. Most oyster kits crop in 7 to 14 days and give two or three flushes.
Chestnut and white button
The chestnut and white button kits grow Agaricus bisporus, the familiar cooking mushroom, using a casing soil layer rather than growing holes. They take a little longer to start, usually 16 to 24 days to the first crop, and reward patience with three or four flushes and a heavier total yield of around 1 to 1.5kg across five to seven weeks. Chestnut has a firmer bite and a nuttier flavour than the white, though the two grow the same way.
Shiitake and lion's mane
These are the gourmet specialists. Shiitake carries a deep, smoky umami that dried and rehydrated becomes stronger still. Lion's mane grows as a shaggy white ball with a texture close to crab or lobster when cooked. Both grow indoors and both are a step up in flavour from the everyday varieties.
Specialist and functional varieties
Beyond the everyday kits, the range runs to enoki, nameko, tarragon and summer oyster, and a reishi kit for growers drawn to the functional mushrooms behind our coffee and hot chocolate. Enoki comes as a White Enoki for indoor growing only, and a Golden Enoki that also grows outdoors as a log kit. If you cannot choose, the two, three and four-kit bundles let you grow several at once.
Which kit is right for you?
+A first-time grow
Start with a white oyster or white button kit. Both crop at normal room temperature and forgive a missed misting. Our blog on the best mushroom growing kit for beginners sets out why.
A warm home
Pink oyster is the only variety that speeds up above 20°C, so it suits a heated kitchen or a conservatory where others would stall.
A cool room in winter
King oyster and black pearl oyster prefer it cooler, around 17 to 18°C, so they suit the colder months and unheated rooms.
Flavour and cooking
King oyster, shiitake and lion's mane are the picks for the pan, each meatier and more distinctive than a supermarket mushroom.
Growing with children or as a gift
Any ready-growing kit works, because the crop appears in the same week and the daily misting is easy to share.
What to expect
+Across the oyster range, the first pins usually show within a few days of the first mist and the first harvest lands around 7 to 14 days from setup. Chestnut and white button take longer to start but crop more times. Every kit gives more than one flush, with the heaviest crop almost always on the first. Grown indoors, the kits crop year round, so you are not tied to a season. To see how each stage looks before your kit arrives, the day-by-day growing timeline walks the full cycle in photos.
When your kit finishes
+A kit is not done when the last flush is picked. The spent compost is peat-free and full of organic matter, so it works as a soil conditioner dug into beds, borders and containers. Our blog on reusing spent mushroom compost covers how to get a second life out of it.
Growing kit or growing from scratch?
+You can grow mushrooms from spawn and raw substrate, but it is slow and easy to get wrong. The substrate has to be pasteurised or sterilised, kept clean while the mycelium runs through it, and held at the right humidity for weeks before a single mushroom shows, and one stray mould can lose the lot. A ready-growing kit skips all of that. The colonisation is done at the farm, so you start at the fruiting stage and see a crop in days. For a first grow, or for anyone who wants the result without the lab work, the kit is the surer route.
Gifting
+A growing kit makes a gift that does something. Chestnut, white and outdoor log kits keep for 2 to 3 months unopened at room temperature, so you can buy ahead. Other varieties are fridge-only and should be started within 7 to 10 days. At checkout you can pick a delivery date and add a hand-written note. Full detail is in the gift ordering guide.
Frequently asked questions
+What is the easiest mushroom to grow at home?
A white oyster kit is the easiest for most people, because it crops at normal UK room temperature and tolerates the odd missed misting. Pink oyster is just as easy if your home runs warm. Both show a first crop within about 7 to 14 days.
How do mushroom growing kits work?
The kit is compost or a log already colonised with mushroom mycelium at the farm. You trigger it to fruit with light, fresh air and daily misting. Oyster kits fruit through holes in the box; king oyster and button kits fruit under a casing soil layer. There are no spores to handle and no sterile setup.
How long do mushroom growing kits take to grow?
Oyster kits give a first harvest in about 7 to 14 days. Chestnut and white button kits take longer to start, around 16 to 24 days, but crop more times. After the first flush, later crops follow every one to two weeks until the compost is spent.
How many times will one kit crop?
Most oyster kits give two or three flushes, and the chestnut and white button kits give three or four. The first flush is always the largest, with each later crop a little smaller as the compost is used up.
Can you grow mushrooms all year round?
Yes. The ready-growing kits are grown indoors at room temperature, so they crop through every season. In summer, keep heat-sensitive varieties like king oyster in the coolest room; in winter, keep the warm-loving pink oyster away from cold spots.
Do I need to grow indoors or outdoors?
The ready-growing kits are made for indoors, at normal room temperature and out of direct sun. If you want a harvest that repeats for years, the outdoor log kits are inoculated hardwood you keep in the garden instead.
Are mushroom growing kits reusable?
A kit crops two to four times before the compost is spent, so you get several harvests from one. After that it is not re-started, but the spent compost is peat-free and works as a soil conditioner in the garden, so nothing is wasted.
Which kit is best as a gift?
Any ready-growing kit works well, because it crops within the week it is opened. Fast varieties like pink and white oyster are popular for the quick payoff, and the mushroom gifts range gathers sets built for gifting.
