6 weeks flower??

i received some clones of a local strain (c3po) and the "owner" of this strain claims it only takes 6 weeks to flower...has anyone ever heard of a flowering time this short or is this guy just rushing his shit? they are at 2.5 weeks flowering now and they did show hairs in as little as 6 days of 12/12...any opinions would be great..

theres actually alot of strains that flower in 6 weeks, pretty sure your good 6-7 weeks.

Gotta give the strains the propper atmosphere to get the flowering time to the low end of things.... Trichs will tell you when they are finished.... I have Seedsman NL growing right now with a stated finish of 6/7 weeks.... They are just pass 6 weeks now and have just started to fill out and one of them showed sex real late and has another 6 weeks to go.... Same exact batch of seeds
