Oldtimer's Haze seeds from Ace Seeds are the result of the preservation of some legendary Haze clones that are said to originate from the distant 70's thanks to the persistence and work of a single English grower. This way, a regular hybrid 100% sativa is presented, ready for harvest after 98 - 140 days of flowering. Its flavor, a delicious and penetrating Haze, brings old school woody, fruity and earthy vibrations. It contains a THC percentage of 12%.

Being regular seeds, it’s possible to get both male (hemp) and female (cannabis) plants.
