Reel 02 From final cut to first fruiting

After thirty-five years
at the cutting-edge,
he started cutting
something else.

Iain Mitchell spent a thirty-five-year career splicing together some of the most-watched television in Britain — an award-winning film editor whose final commission, fittingly, was a certain farming series you may have heard of. Somewhere between the Clarkson fields and the farm-shop walk-ins, a question took root. What if the thing on the chopping board came from fifty feet away, not five thousand miles?

In October 2025, he swapped the edit suite for a growing room in West Wycombe. Six varieties. Hand-cut. Harvested at dawn, in the kitchen by lunch. Mycelium grown on locally-sourced substrate. Fruiting rooms dialed in like an audio mix — humidity, CO₂, temperature, light. Nothing flown. Nothing forgotten in transit.

"I spent thirty-five years making pictures move. Now I'm watching mushrooms grow. Honestly? Both feel like magic."

The farm supplies local farmers' markets, farm shops, pubs and restaurants within the Chiltern Hills — and posts a weekly harvest list to a small network of home cooks who like knowing the name of the person who grew their dinner. If that sounds like you, you're in the right place.

Reel 07 Frequently asked

Nine small things,
answered.

How fresh are these, really?
Cut the morning of delivery. If you order for Saturday, the mushrooms you unwrap were still growing on Friday night. That's why we deliver within roughly 10 miles — further than that and the numbers stop working.
Do you grow organically?
We grow with sustainable, low-impact methods: no pesticides, no fungicides, UK-sourced substrate where possible, and we re-use spent blocks as garden compost for neighbours. Certified-organic paperwork is in progress for 2026.
What's the minimum order?
One 200g tub of any variety for delivery. For restaurants and pubs, we usually start around 2kg a week across varieties — get in touch and we'll size it to your menu.
How long will they keep?
Stored loose in a paper bag at the bottom of the fridge: five to seven days for oysters and chestnuts, seven to ten for shiitake and lion's mane. Never in plastic — they want to breathe.
Can I visit the farm?
Yes — by arrangement. Contact Iain first so he isn't elbow-deep in a fruiting chamber when you arrive, and he'll set a time for you to come to the farm.
Do you ship nationally?
Not at the moment. Our whole model is: cut in the Chilterns, eaten in the Chilterns. A courier-ready pack-out may come in 2027 — drop us an email if you'd like to be told.
Are the mushrooms wild-foraged?
No — the six varieties on the weekly list are all cultivated on the farm, grown indoors on locally-sourced substrate rather than picked from the wild. That's how we keep them consistent, clean and available every week.
Do you supply trade?
Very happily. We currently work with a handful of pubs, restaurants and farm shops across Bucks and south Oxon. Drop us a line for the trade sheet and current lead times.
Why "Head Fun-guy"?
Because every farm needs one. And because after thirty-five years in the edit suite, you're allowed a pun.
