What I know about New pUrple Power is it does great at highlatitudes, Washington-US, Vancouver-CA, as well as in Europe Holland, Denmark. Outdoors grow it right, getting a little colder near harvest with make the buds intensly purple. Hope you get better growing info...I also got this from Tarka the Otter its about regular Purple Power (very similar)

ok, this is what you do to start off with. Amonth before you plan on planting the seeds germinate them, and grow them under lights (2x18watt fluoros will be more than enough). give them seperate plant pots and also create a green house for them using clingfilm/cellophane food wrap. Keep the light cycle on 18/6 as per any indoor vegetative stage. Doing this this way will give the plants the extra strength they need to survive outdoors in spring. I don't know what the weather is like in canada where you are but I do know the inconsistant weather at home in Wales, U.K. What I normally do with my plants is start growing them indoors around december time under the fluorescent lights so the have four to five months of vegetative growth before the sun even hits them. By this stage they already have thick trunks and are ready to give enormous harvests by the end of autumn. They suffer a mild shock being transfered from my attic to the mountains but are over that within days of the fresh air and sunshine. Also, the air movement causes the chrystals to grow at an excelled rate which give a minor increase in THC levels. I hope you find this info useful bro and have fun growing the green.
