How to grow Auto Jack
Seb's take
Jack Herer and White Widow, with Ruderalis brought in specifically to tame the sativa sprawl and shorten the wait to ten or eleven weeks. Fruity, hashy character is the promise here, in a plant still hefty enough to reward Screen of Green training. A sativa in spirit, if not in patience required.
Growing Auto Jack: what to expect
She's an auto — on her own clock from the day she sprouts. No switching lights, no waiting on seasons, and no pausing while you sort problems either; read how autos differ before day one.
A 10-week flowering run — the scenic route. Worth it, generally, but plan your season around her rather than the other way about. See the flowering stage.
Expect 450 g/m² — a working grower's yield, reliable rather than theatrical. The harvest guide will see it in safely.
Listed at 18% THC — potent, verifiably. The figure comes from the breeder's testing, not from our enthusiasm.
