Im growing outside in denmark not england.Denmark is colder than in uk too but as long as you give em a good start indoors on the window sill or under lights if ya want by the begining june Im gonna put mine outside. there aint too much rain in the summer and the temp aint gonna go too low either. I really think you can have sucess.In uk no probs. Right now the temp here is 20/21 the temp aint gonna go much below that and its the summer time so better weather to come. I fully understand that the weather back home in uk is ever changing but you wont know till ya try will ya!
