Green Haze 19 A5 takes its name from its highly distinguished lineage. A cross between Ace Seeds best Green Haze mother (#19) from the Oldtimer’s Haze line, and the elite clone of A5 Haze (NL # 5 x Original Haze male A) from Nevil, resulting in a hybrid of almost pure Haze expression with renewed vigour, combining legendary old expressions of green Haze (19, similar to the old green Colombians and Colombian Gold) and brown Haze (A5), both very incense and of excellent quality, which recall some of the best Colombian sativa expressions of the 60s and 70s

The Green Haze #19 mother clearly dominates in this hybrid with her tropical sativa character, both in growth and flowering traits as well as in her psychoactivity. The powerful A5 Haze brings plenty of vigour and yield, and its distinctive classic Colombian Haze aromas which, together with the aged and exotic terpenes of Oldtimer’s Haze, come together to create a bouquet, personality and effects that will excite the most purist of Haze hunters.

The extremely stable pure Oldtimer’s Haze genetics provide uniformity to the highly heterozygous F1 NL Haze, fixing its tropical nature and pure Haze traits so that the influence of Afghan indica from Northern Lights is, in this case, so recessively relegated that it disappears from the phenotypic expression of the final hybrid.

The flowering times of Green Haze 19 A5 are long, as you’d expect, and they fall just halfway between A5 Haze and Oldtimer’s Haze. The late harvest is compensated by an overwhelming quality and undistorted true Haze character, and by a good yield that rarely suffers losses due to the excellent genetic resistance to cold, rain and botrytis-type fungi.

Breeding their best incense parentals of pure Oldtimer’s Haze with Nevil’s most powerful and also incense Haze hybrids allows the union of 2 mythical incense Haze lines of incredible quality, reputation and influence (Original Haze and Oldtimer’s Haze), bred separately for decades to now finally merge into this genepool dreamed of by all Haze lovers.

Elegant, very well-branched and flexible Sativa, with narrow leaves and medium-long internode spacing.

Ripe mango bouquet, cured wood, incense, lightly spicy and metallic notes from Green Haze #19, with the unmistakable meaty background and decaying flowers of A5 Haze.

Highly cerebral effect: clears the brain. Sensory perception is sharpened and amplified. Soft start, which progressively rises and rises, becoming very energetic to take off on time, from then on it becomes more powerful and crazy, although always very clean, being warmer, happier and more expansive than its Purple Haze 23 A5 stepsister.

It mainly contains the following monoterpenes: very high amounts of beta mircene, and moderate amounts of trans ocimene and alpha pinene. Without relevant presence of sesquiterpenes.

It can be grown indoors with strong light intensity and with enough space for its development. Ace Seeds recommend to switch her into flowering after 15 days from seed, or starting from clones rooted for at least 7 days. Ace Seeds recommend 11 (light)/13 (darkness) photoperiod for the flowering indoors, in order to boost the flowering, and to avoid reflowerings or excessive stretching in early flowering.

Very suitable for SCROG, horizontal or network growing due to its excellent yield in the lateral branches and its vigorous reaction to pruning.

Outdoors, it is especially suitable for outdoor cultivation in tropical or subtropical climates, although it can be cultivated with very good results in warm coastal climates of mild autumn (similar to the Mediterranean) up to latitudes close to 40º.

Ace Seeds recommend low-moderate levels of nutrients for the whole cycle.

A feminized limited edition, available while stocks last.
