Z7 from CBD Crew is part of the Z series of strains that consist of carefully selected phenotypes created from crossings of Cannatonic, from Resin Seeds, with Skunk and Afghan. The series was released as a limited edition and may no longer be available. It is worth mentioning here though as the genetics have gone on to form the basis of new medicinal strains, notably 303 Ambulance and 303 Meltdown from Colorado.Z7 was released in both regular and feminized forms. The regular version comes from re-crossing the selected F1 Cannatonic female with the Skunk/Afghan male. To feminize it the Cannatonic was reverted with Silver Thiosulfate (STS) to release pollen and act as the male.Z7 burns with a strong berry/orange peel scent. Buds are large with long foxtails. There may be some instability in the strain with a number of different phenos to be expected.Whilst CBD Crew gives no information on the flowering period, we have read reports that say 9 – 10 weeks is optimum for the highest THC and CBD levels.Any growers who have first-hand experience with this strain, please let us know your results in the comments section below.VN:F [1.9.22_1171]Rate this content...please wait...Rating: 7.8/10 (5 votes cast)CBD Crew - Z7 Feminized Marijuana Seeds, 7.8 out of 10 based on 5 ratings StrainIndica dominant hybridSeed OriginCannatonic X (Afghan X Skunk)Seed BreederCBD CrewAuto Flower Seeds AvailableNoFeminized Seeds AvailableYesGrow IndoorsYesGrow OutdoorYesYieldMediumHeight IndoorsmediumHeight OutdoorstallFlowering Period9 – 10 weeksHarvest Outdoorn/aTHC LevelHigh CBD: HighStoned or HighstonedGrow DifficultyeasyAwardsNoneWhy buy CBD Crew – Z7 Feminized Seeds here?Since 1999 we have dealt with over 30 international seed banks and we only trust these guys.
