Funny.......I've read many grow reports on the SP, especially on Opengrow (Sannie's forum site) and many people comment on how it continues to elongate well into the 4th week of flowering. Normally some are shorter, but a % of them really show the sativa heritage and grow to 6-7 ft if you don't bend or pinch them. I own the seeds but have hesitated to grow them because of the height issues. Now I'm not so sure.......
