How to grow Auto Jack Herer
Seb's take
Advanced Seeds' own selection of Jack Herer, autoflowered but no less generous with resin — thick, heavy buds on wide branches. Sweet, fruity and floral on the nose; the high is relaxed, happy and euphoric, dense in flavour in a way the breeder is plainly rather proud of.
