Green Haze Regular by ACE Seeds

This is a regular variety ideal for growers and breeders seeking to work with a true old school tropical sativa rooted in classic Haze genetics. Within the ACE Seeds range, it stands out as one of the purest and most authentic Haze strains, built from historical tropical sativas from the 1970s—including green Colombian, Kerala Indian, and Thai lines.

Cultivation-wise, Green Haze develops into an extremely tropical, slender, and elegant plant with fine leaf structure, strong vigour, and flexible stems. It is not suited for quick turnaround cycles but rather for experienced growers who appreciate long growth periods and true sativa characteristics. This unique morphology makes it especially valuable within ACE's breeding program.

With a flowering time of 14 to 20 weeks, Green Haze is one of the latest finishing regular sativas in the ACE range. It typically yields medium to lower amounts, which aligns with its focus on quality and genetic purity rather than high yield. The THC content ranges from 8 to 12 percent, with CBD below 0.05 percent and CBG around 0.16 percent. It is recommended for latitudes between 0º and 37º, showing medium resistance to spider mites, medium to high resistance to powdery mildew, very high resistance to botrytis, average-high resistance to white fly, medium cold tolerance, and high heat resistance.

Green Haze is defined by its uncompromising tropical character. It is best suited for sativa enthusiasts, breeding projects, and seed production rather than growers focused on fast and uniform harvests. Indoors, it benefits from adjusted photoperiods and active plant management. Outdoors, it thrives in tropical or subtropical conditions, or in very warm coastal areas with greenhouse support.

Aromatically, Green Haze leans into a classic old school profile—blending wood, spice, incense, and ripe mango. Its terpene profile is dominated by high levels of beta-myrcene, with moderate trans-ocimene and alpha-pinene, alongside smaller amounts of beta-pinene. In the sesquiterpene fraction, beta-caryophyllene and alpha-humulene stand out. Combined with its mental, stimulating, social, and euphoric effects, it offers one of the purest old school sativa experiences in the ACE lineup.
