Thank you!
I think I’ve got about 175 m2 or just over, for two people. Not liking cauliflower sounds like it should help. I am prepared to put in a lot of time and effort, the weather is good in Sussex and there will be a proper poly tunnel next year, this year there is a 1.2 x 2 meter one, looked disappointingly small when I got it home! I’m going to concentrate on the expensive veg and herbs that we buy to save the most money.
