Description
Rooted in a lineage that reads like a California classic, this feminised sativa from Humboldt Seed Co. combines California Haze, Original Haze, and the legendary Arcata Trainwreck into something genuinely distinctive. The aroma leans into fresh pine with a floral lift, and the effects follow suit: energetic, creative, and unmistakably uplifting, with very high THC levels above 25% that demand a measured approach from newer consumers.
As a large, sativa-dominant photoperiod plant, California Haze will stretch considerably once the flip to 12/12 is made, so indoor growers should plan for aggressive training, topping early, and generous canopy space. A flowering window of 9 to 11 weeks is on the longer side, rewarding patience with the complex terpene profile that only extended ripening can produce. Outdoors, her sativa structure thrives in warm, Mediterranean-style climates with a long, dry finish to the season. For growers willing to give her the room and time she asks for, this is a cultivar that consistently delivers on the promise of West Coast haze genetics.

FAQ
All you need to know
about this product
California Haze Feminized brings Humboldt's legendary Haze and Arcata Trainwreck lineage together in one high-yielding, creatively charged sativa ready for growers who know their craft.
This is a moderate-to-advanced grow, so it rewards growers who already have a few harvests under their belt. The large, stretchy sativa structure and long flowering window of 9 to 11 weeks require confident canopy management and patience, but the payoff in both quality and quantity is substantial.
The profile leans into fresh pine with a floral lift running through both the grow room and the final product. It's a clean, classic West Coast aroma that reflects the Original Haze heritage at the heart of its genetics.
The effects are energetic, creative, and uplifting — the kind of cerebral experience that sativa enthusiasts actively seek out. With THC above 25%, this is a cultivar that commands respect from newer consumers, but experienced users will find it delivers exactly the high-octane lift Humboldt intended.
Indoors, well-managed plants can produce 450–600g per square metre, while individual plants in ideal conditions can reach 450–750g. Being a large sativa-dominant photoperiod, expect significant vertical stretch after the flip to 12/12, so low-stress training or topping early is strongly recommended.
