Our take
Z-Up Auto brings serious potency from its RS 11 Cut parentage — up to 29% THC — in a sativa-leaning plant that finishes in just 8 to 9 weeks without any light-schedule changes. The flavor profile runs fruity and bright, with a pronounced lime-soda tartness. Suitable for growers who have a harvest or two under their belt and want a high-performing autoflower.

Growing notes
Z-Up Auto grows large for an autoflower — expect 28 to 47 inches at harvest — so give it vertical room, especially indoors. It suits indoor, outdoor, greenhouse, and mixed-light setups. The 8–9 week total cycle from seed to harvest makes scheduling straightforward. Intermediate growers will get the most from this variety by managing canopy height and feeding consistently through its fast development.
