Winter in the GH & PT

I've never bothered with winter crops, either indoors or outdoors, except for leaving swiss chard in the ground in the hope it might revitalize in spring. Experiments with brasssicas in the past failed miserably. Last year used the GH to overwinter fuschia with some sucess. This year's halfhearted plan is to have something growing but I'm not sure what. I've some arctic king in the border soil, which got munched by caterpillars, but as we don't eat many, I wasn't too heartbroken. Some carrots in pots, some chard modules. I find if the weather is grotty I tend to neglect the GH. Time will tell whether I shall succeed this coming winter. My last 10 hour day day is 24th October, about 12 weeks away, so there's a reasonable choice of things to sow.
