Grow your own Mushroom Kit

What’s Inside Your Mushroom Gift Box?

Each Mushroom Gift Box arrives with everything you need to grow your own delicious crop at home — all you’ll add later is the fresh mushroom spawn (think of it as the seed), which is sent out when you redeem your gift.
You’ll find the full contents in the product photos.

Because there’s nothing “live” in the box until you’re ready, these kits are wonderfully low-maintenance: they store happily for up to 12 months, no fridge needed. They make a thoughtful gift for any food or garden lover — or simply a fun little project to start when the mood strikes.

As with the rest of our range, every kit is 100% peat-free, and all packaging and materials are recyclable or compostable. And if you’d like a hand along the way, we’re here with full online support to make sure your mushrooms have the best possible start.

Grow at your own pace, give a greener gift, and enjoy the thrill of harvesting your own mushrooms — with a little guidance from us.

A Few Important Bits to Know

Our kits are designed for growing indoors, where the temperature and light are naturally just right. Every kit and every batch of spawn is prepared in small runs, then packaged fresh on the farm and sent directly to you for the best possible quality.

With our guaranteed first flush, you’ll usually pick around 200g of fresh mushrooms over your first two harvests — and many growers get even more by following our simple tips for extra flushes.

What’s Inside Your Kit

Recycling Your Kit
