Growing good-sized calabrese

Just PSB for me after this year ...calabrese and cauli are now on my banned list. Too much trouble for just a few heads that may or may not grow to a decent conclusion, and even then there is a final wildlife problem. I grow 40 odd different veg, fruit and herbs. Something has to give. I'm supposed to be a local enthusiast growing sustainably ...  not an imitation of an unsustainable supermarket display of decadence.
