Yes I've also heard this but I don't know if it's really true...I think mainly what your looking for for that climate is a quick flowering indica.Something that you can harvest before the bad weather really starts...like a 7-8 week Afghani,but bud densidy might be a problem in a wet climate so look for a quick flowering mostly sativa hybrid...75%sativa and 25%indica or a 50-50 cross if your climate is humid.Sativa bud structure is more airy or this reason.Afghani's are for a dryer climate,but I don't really know what it's like there.Hope this helps
