(Ace Seeds)
Green Haze 19 A5 Hybrid feminised seeds produce an almost pure Haze hybrid, blending Ace Seeds’ Green Haze #19 (a standout from their Oldtimer’s Haze line) with the legendary A5 Haze (Nevil’s NL #5 x Original Haze male A)
This combination unites iconic green and brown Haze expressions from the 1960s-70s Colombian sativas, offering a true homage to the origins of Haze genetics.
The hybrid prioritizes tropical sativa traits, ensuring a genuine Haze experience, with minimal influence from Northern Lights’ indica genetics.
It delivers vigor, yield, and resilience, paired with a complex aromatic profile and a profoundly cerebral effect that is sure to captivate Haze purists.
Key Features:
Genetic Lineage:
Green Haze #19: Tropical sativa dominance with traits akin to old Colombian Gold and green Haze.A5 Haze: Adds vigor, yield, and its renowned Colombian Haze aromas.
Aroma & Flavor:
A mix of ripe mango, cured wood, incense, and hints of spice and metal from Green Haze #19.Combined with meaty undertones and decaying flower notes of A5 Haze, creating a unique bouquet.
Effect:
Highly cerebral: Sharpens sensory perception and progressively rises to an energetic peak, leading to a clean, happy, and expansive high.More euphoric and warmer than its Purple Haze 23 A5 sibling.
Flowering Traits:
Flowering Time: Falls between the extended cycles of A5 Haze and Oldtimer’s Haze.Resistance: Excellent tolerance to cold, rain, and botrytis fungi.
Yield: High, particularly on lateral branches, making it SCROG and pruning-friendly.
Growth Characteristics:
Sativa Dominance: Elegant, flexible, narrow-leaf plants with medium-long internodes.Requires strong light intensity indoors and thrives with an 11/13 light/dark cycle to minimize stretch and early reflowering.
Outdoor Cultivation: Ideal for tropical, subtropical, or Mediterranean-like climates.
Nutritional Needs:
Low to moderate feeding throughout the growth cycle.
Haze Connoisseur’s Dream:
Green Haze 19 A5 represents a merger of two mythical Haze lineages, refined over decades:
Oldtimer’s Haze for its tropical sativa purity and exotic, aged aromas.
Original Haze through A5 for its vigor and unmistakable incense character.
This results in a genetic pool combining Colombian sativa traditions with the innovation of modern Haze breeding, creating a limited-edition feminized hybrid that will captivate enthusiasts of classic incense sativas.
