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.

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.
