Purple strains are supposed to do very well in the UK climate due to early finishing time. Im considering an outdoor grow myself this year, Im hoping to get a polythene greenhouse next month. Ive got some SK#1 and some SK#1xDurban to do also, hopefully they will be ok in the greenhouse even of there is a little frost. As mistysantamaria said, "Youve nothing to lose".
