Should be just fine, Im not familiar with the climate over there in the UK but as long as its not getting close to freezing temps shouldnt have any worries. Im lucky living in northern California where there isnt a strain on this earth that wont grow here, obviously some better than others but especially down in the valley where I am we have one of the greatest natural climate/soil for many different agricultural crops, although I do backfill all my outdoor pits with mainly ff ocean forest and a mix of worm castings, shroom compost, bonemeal, blackgold, perilite and a touch of dolo.lime....works wonders...got plants ranging from 7-12ft right now just starting to flower, theres nothing like outdoor growing. Good luck and happy growing, peace!
