I had a Great White Shark out last year.. I had to pull it around 3 weeks early and still yeilded around 2.5oz off a 3' plant.. GWS probly wont be done until the 3rd week of October in Southern ON.. Im gonna try running Frisian Dew, Passion #1 by Dutch Passion, possibly Durban Poison by them (although it wont be ready till the first week of November probly).. Mendocino Madness is a good fast flower I've heard.. Passion #1 flowers in 6.5 weeks, and Frisian Dew in 7 weeks and is a nice purple plant.. Hope this helped a little..
