I think you will be fine with temps in your basement mate. Ah the Great White Shark, also known as Peacemaker. The genetics make it sound like a great strain, also one I would like to do one day. It's funny, we were on about this the other day, Peacemaker has a bad reputation around my end, people say its that "peacemaker shite". These are people who haven't got a clue about strains, and I think it is all in the name, a marketing sort of thing.
For example someone said I don't like Peacemaker, so I said, what about Great White Shark? An he was like "yeah it sounds fucking wicked that, bet it smashes ya"
Same strain, dick head. lol
