A polytunnel looks like a practical decision. More growing space, longer season, protection from rain and frost.
What it actually changes is harder to see from the outside.
Farmers in our community who grow under cover tell us the yield gain matters less than the timing gain. You can bring strawberries to market three weeks before anyone else in your region. You can extend tomatoes into autumn when outdoor crops are done. That gap - those weeks - is where the price premium lives.
The buyer who relies on you for out-of-season produce pays differently than the buyer who can find the same thing from five farms in July. That relationship, built on consistent supply at a time when supply is short, is often worth more than the extra volume.
The problem is the entry cost. A tunnel of any useful size is a serious investment. The farms that have them often got there through grants, cooperative purchasing, or years of reinvested margin. For a smallholder starting from scratch, it's out of reach in the first few seasons.
We're curious: in your region, is protected growing spreading to smaller farms - or is it still concentrated among the bigger operations? 👇
