Big Jack — 3 versions compared
Big Jack is sold by 3 different breeders in this library, 3 of them listing a flowering time. They are not the same plant: different breeders' cuts and crosses of a famous name vary in structure, flowering time and lineage. This page puts them side by side.
Listed flowering times across these versions run from 60 to 90 days. That spread is breeder listings, not measured results — which is exactly why the number worth trusting is the one from your own journal.
| BREEDER | FLOWERING | TYPE | LINEAGE |
|---|---|---|---|
| GreenLabel Seeds | ±63 days | mostly sativa | Big Bud × Jack Herer |
| Queen Seeds | ±60 days | indica/sativa | Jack Widow × Critical Plus |
| The Moon Seeds | ±90 days | ruderalis/sativa | Auto Jack × Auto Haze |
Which one should you grow?
Listings are marketing copy, and the same name from two breeders can behave differently in the same tent. The useful comparison is not between listings but between your runs: log feedings, readings and photos, and let the trends decide. Start a free Big Jack journal →
