Back on during unsettled weather?

[Florence Fennel]

Thanks Charles, is it worth putting it back on for the few days of less favourable conditions currently forecast, or should they be sufficiently established by now (ours have been out for about a week and a half)?

We used fleece a lot more for our early plantings this year and it seems to have made a real difference (especially for lettuce and beetroot), so keen get any further advantage I can!
