Ace Seeds' Killer A5 Haze Regular is a cross of A5 Haze & Malawi, offering high-impact sativa effects & yields.

Killer A5 Haze Regular by Ace Seeds is a premium, sativa-dominant hybrid that fuses two legends: the ultra-rare A5 Haze mother and the potent killer Malawi. A5 Haze, a Northern Lights #5 x Haze A hybrid developed by Neville Schoenmakers in the late '80s, is considered one of the most powerful Dutch Haze elite clones still in existence. Known for its deeply psychedelic, mind-warping high, A5 Haze features a bold terpene profile with rich, incensed, meaty, and earthy aromas that reflect strong Colombian sativa influence—true to the “Old School” Haze experience. This elite clone has never been available in seed form due to the early loss of the Haze A male, making it a rare collector’s gem now revived through expert breeding.

By crossing A5 Haze with killer Malawi phenotypes, Killer A5 Haze Regular amplifies potency, yield, and resin production while reducing flowering time—without compromising its pure sativa spirit. This hybrid can reach THC levels up to a staggering 30%, offering some of the most intense psychoactive effects on the market. Despite its powerful growth and high vigor, it maintains a manageable size with excellent structure for both indoor and outdoor cultivation. Flowering time has been significantly reduced compared to traditional Hazes, with earlier blooming response and faster finishing times, even outdoors. Ideal for experienced growers seeking top-tier yields and maximum cerebral impact, Killer A5 Haze Regular is Ace Seeds’ most productive sativa hybrid per square meter—combining elite genetics, extreme potency, and true Haze authenticity in one unforgettable strain.
