Green Haze 19 A5 takes its name from its highly distinguished lineage. A cross between the 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. This is a hybrid of almost pure Haze expression with renewed vigour. It contains the legendary features of Green Haze (similar to the old green Colombians and Colombian Gold) and "brown" Haze (A5). Both have a strong incense aroma of excellent quality, reviving some of the best Colombian Sativa expressions of the 60s and 70s. For the first time these two mythical incense Haze lines of incredible quality, reputation and influence (Original Haze and Oldtimer's Haze), finally merge into one genepool dreamed of by all Haze lovers.

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 purists among Haze hunters.

The extremely stable and pure Oldtimer's Haze genetics provide uniformity to the highly heterozygous F1 NL Haze. Its tropical nature and pure Haze traits override the influence of Afghan indica from Northern Lights, so there's no phenotype expression of the latter.

This strain can be grown indoors with strong light intensity and enough space for its development. Low-moderate levels of nutrients are required for the whole cycle. Green Haze 19 A5 feminized is a branchy flexible Sativa, with narrow leaves and medium-long internode spacing. Ace Seeds recommends switching to flowering after 15 days from seed, or starting from clones rooted for at least 7 days. A 11-13 light cycle for flowering indoors boosts bud development, avoids reflowerings, and excessive stretching in early flowering. Very suitable for SCROG, horizontal or network growing due to its excellent yield in the lateral branches and vigorous reaction to pruning.

Green Haze 19 A5 can be cultivated outdoor in tropical/ subtropical climates, also with very good results in warm coastal areas with a mild autumn (Mediterranean, etc) up to 40°N. The flowering times of Green Haze 19 A5 are long and fall 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, powdery mildew and botrytis.

And now to the main event: the high is strongly cerebral and heightens sensory perception. After a gentle start you'll feel progressively uplifted, with very energetic phases coming through. As it reaches peak intensity there is a powerful and sometimes unpredictable effect. The high always remains very clean, being warmer, happier and more expansive than its Purple Haze 23 A5 stepsister.

This is a limited edition of feminized seeds, available only while stocks last.
