Im guessing that the pineappleas and sweet potatoes fro the veg boxes come on the same boats as those you find in the market or shops...they wont have special transport for veg box schemes. So inthis respect you may as well just buy said pineapple from wherever is cheapest.
Fair enough if your veg box is local...but that still doesnt meanthte veg is local , if so surely all you are getting atthe mommetn in that case is asparagus, broad beans and kale and new potatoes if you live in jersey or cornwall...other than that no veg ready yet judging by my allotment that is! If you are getting old potaoes then they will have been in cold storage since sep...and sprayed with inhibitor to stop them sprouting!
