Merryhill Mushrooms is a family run business based in Storrington, West Sussex, growing and advising on mushrooms since 2006. The company was started by Dick Rucklidge, who had been in the mushroom industry for over 50 years and worked as the leading consultant in the country for 30 of them.

Dick travelled across the globe lending his experience to others and sharing his passion for all things mushrooms. That wealth of knowledge now goes into every kit we produce, hand-planted in small batches right here on the farm.

An Idea Is Born

Everyone kept telling us the same thing: they had never managed to find a mushroom growing kit that actually works. Not happy with what was available on the market, Dick came up with the concept of our own grow boxes.

With high-yield compost in every box and decades of commercial growing knowledge behind the design, our kits produce mushrooms with a much better taste than anything you will find in a supermarket. Those who have grown with us will agree that the difference is huge.

Our kits are "ready growing" which means the hard part of mushroom cultivation, the spawn run and colonisation, has already been completed before the kit leaves the farm. When it arrives at your door, the mycelium is fully established and your first harvest is days away, not months.

All indoor kits grow between 14 and 21 degrees with an optimum of 17 to 18 degrees, making them well suited to UK homes year-round. No greenhouse, no grow tent, no special equipment. Just a spray bottle and a suitable spot away from direct sunlight.

Beyond Growing Kits

Using only high quality mushrooms and ingredients, we expanded our award-winning range into food and drink. Our adaptogenic drink range includes instant and ground mushroom coffees plus a mushroom hot chocolate. All products use fruit body extracts only, made in the UK.

We also supply A-grade dried porcini, wild mushroom mixes and porcini powder for home cooks and trade buyers. These are the same products we supply to Sussex restaurants and farm shops.

Our mushroom growing kit range includes Chestnut, White, Shiitake, Lion's Mane, Pink Oyster, White Oyster, Black Pearl Oyster, King Oyster, Nameko and Reishi.

Chestnut and White are the most beginner-friendly. Shiitake offers the fastest first harvest at 7 to 10 days. Lion's Mane produces a striking mushroom with a seafood-like texture that is hard to find in supermarkets. We also sell outdoor log inoculation kits for Shiitake, Lion's Mane and White Oyster.

New for 2026

We are always developing new varieties and improving the growing experience. This spring we are launching three new kits to the range:

Black Pearl Oyster — A King Oyster variant with thick, meaty stems and small dark caps. Grows in a log format with topsoil and plate setup. Harvest in 15 to 20 days.

White Oyster — A delicate, mild-flavoured oyster mushroom that grows in clusters from a ready growing box kit. Fast growing with a first harvest in 7 to 10 days.

Enoki — A Japanese favourite with long, delicate stems and tiny caps. A staple in hot pots, soups and stir-fries. Launching April 2026.

Growing kit orders placed before 2pm are typically dispatched the same day via DPD for next-day delivery to UK mainland addresses. We also deliver to the Scottish Highlands, Islands and Northern Ireland.

Mushroom growing kits make popular gifts. Let us know at checkout and we will adjust dispatch to ensure maximum shelf life. Ready growing kits can be stored in the fridge for up to 10 days before starting.
