FAQ
Questions? We've got you.
Will it arrive in time for Christmas?
Yes. Order by Monday 21 December and your kit is guaranteed to arrive before Christmas. Choose your delivery option at checkout.
Is it hard to grow?
Not at all. It's three simple steps: add boiling water, mix, and grow. No experience, no green fingers, no special kit needed. If anything goes wrong, our diagnosis tool walks you through it.
What if it doesn't grow?
It's covered by our growth guarantee. If your kit doesn't grow, we'll send a free replacement. No quibble.
Can I send it straight to the recipient as a gift?
Yes, just enter their address at checkout. We don't include any prices or invoices in the box, so it's ready to give.
Wait, is this the "magic" kind?
No! These are gourmet, edible mushrooms, the kind you cook and eat. Delicious, completely legal, and genuinely good for you.
How long until they're ready, and how much will I get?
You'll see your first mushrooms in around 30 days, and each kit produces roughly 3–6 meals' worth across multiple crops.
The gift that actually grows.
Growth guaranteed. Free replacement if not. One donated to a school.
