Endless Sky - Dr Greenthumb: 6 weeks flower, very potent indica stone, 500 g/m2 sog, very good quality stone. Great breeder, time tested, will reship if you don't receive your beans, has a High Times top 10 strain 2009 (Cindy 99).
If you're going commercial go with the regular over feminized seeds for sexual stability, and take a clone from the plants in seed (for a mother), label clones and plants from seed well, keep your mother for the shortest flowering plant and toss the other clones. I've read 6-10 weeks flower from the same seed pack around the web, this is normal - just pick your 6 week clone for a mother and you have 6 week plants as long as you can keep your mother string going.
Cure and vaporize your plants from seed before chucking the mother clones, see which plant tastes best, is most potent, etc. Trade that off with flowering time and yield to see which mother you want, toss the other clones.
I've grown Doc's Big Laughing and an unknown mix strain, both were great and I still have my Big Laughing mothers 2 years later.
Order by call in pre paid credit card or send a money order or bank draft and get postal tracking (no signature, just tracking number). Send no cash. Canadian postal employees who steal mail don't go to jail, they go to rehab then back to work. Trust no cash in Canadian mail. (I live literally a stones throw from a mail man who stole mail for years looking for cash, then when caught said that he did it to support his coke and heroin habit. Rehab, back to delivering my mail. Great union, weak employer. Great mail service though, the Cliff Claven of world postal services..
