What makes autoflowering seeds different?
Autoflowering refers to a botanical trait: the plant’s transition to flower is linked to age rather than daylight sensitivity.
For collectors, this trait marks a distinct category in seed libraries, with many classic and modern lineages offered in auto versions.
Today’s autos come from careful breeding focused on aroma, flavour profile, and stable expression.
