Description

If you’re in the mood for a ‘blast from the past’, Kees’ Old School Haze is your go-to. It’s a 100% pure sativa that grows quickly, designed for the experienced grower who can maintain a stable environment. Offering massive yields after a 12-13 week flowering period, this strain presents musky, ammonia-like aromas with a hint of fresh citrus. When smoked, it delivers a hazy, trippy experience thanks to its strong effects. As a cornerstone of the Super Sativa Seed Club for nearly 35 years, Old School Haze invites you to relive the original sativa taste-experience.

  • This is a bit of a sensitive lady. She will produce arm-long buds with the right treatment. Make sure your room/tent is ventilated properly day and night. Try to grow at 25/26 oC constantly. An air conditioning unit will be the ticket to success in hot climates. Excessive temperature swings will make her shoot out thin useless branches that produce tiny buds and can be slow to ripen.: This is a bit of a sensitive lady.
