well they have an auto version & a fast version that was crossed to an auto then crossed back to green poison finishes in 6-7 weeks. The regular version is suppose to finish they say in 7 weeks so i dont know how accurate the regular version is but ive grown the fast version & it always looks done at 6 but i take them at 7 weeks. I'm not sure if sweet seeds are on here but they are on icmag & will answer your questions if you go there.
