I’m sure you will be thrilled with the produce you can grow in your polytunnel. We had just a small one three years ago and it’s wonderful. Food all year round. We do have a bit of powdery mildew but it’s not a huge problem. We keep mesh on the doors until heavy frosts then cover that with fleece until it’s warm enough to remove again. Your big one will perform wonderfully well, I should think.
Charles is the best guru when it comes to sensible and productive gardening. John Walker is another name I go to for good advice and environmentally sound ideas even though I’ve probably been gardening longer than the two of them. You’re never too old to learn. No-dig is not only the best practice for soil management it is also better for my 69 year old muscles and back and my 5′ 1″ frame!
Good luck with your endeavours.
