Brassicas and winter weather

Brassica grower Geoff Philpott knows a thing or two about the weather, he is a keen amateur weather watcher.  Apparently we are now in a new 22 year sun cycle, which started 2 years ago and this cycle means much colder winters. Geoff grows over 120ha of brassicas, with over 100 varieties of cauliflowers, on the Isle of Thanet in Kent. One tip is to grow the plants closer in the row, but place the rows further apart.
