“Killer A5 Haze” Feminized Cannabis Seeds – ACE Seeds

ACE Seeds has struck again with Killer A5 Haze, creating a monstrous new sativa hybrid that has the potential to produce the most potent, highest THC-heavy plants in the Ace Seeds catalog to date!

A5 Haze is one of the rarest (and probably the most potent) mothers from the elite Dutch clone family of Haze hybrids that Nevil Schoenmakers developed in the late 1980s and are still preserved today.

This Northern Lights #5/Haze A mother is characterized by her extremely extravagant and devastating potency, high production and her incense, organic and meaty aromas of authentic Dutch “Old School” Haze with a greater influence of ancient Colombian sativas.

The rarity of this A5 Haze mother is due to the fact that Nevil lost the Haze A male very early meaning that seeds have never been produced in commercial quantities using this Haze A male.

With Killer A5 Haze their main goal was to create a sativa-dominant hybrid that maintained (and even surpassed) the extreme potency, high vigor and high yields of the A5 mother, and they achieved this by hybridizing her with killer phenotypes from our mighty Malawi, with which Ace Seeds have increased the THC content even further, reaching up to 30%!

At the same time we greatly increased the resin production and the size of the trichomes, and reduced the long flowering time of A5 Haze to something more moderate (not only indoors, but also in its faster reaction to flowering outdoors ) without having to introduce indica genetics.

Despite her great sativa vigor and very high production, Killer A5 Haze grows to a small and manageable size, making her our sativa-dominant hybrid with the highest production per m2.

In Killer A5 Haze we find 4 phenotypes:

– Haze dominant phenotype: This phenotype is the one that shows the most Colombian sativa influence from the Haze A male, producing huge and beautiful buds with an excellent flower to leaf ratio, which mature into elegant and delicate re-flowering.

Woody and incense aromas of pure Haze. The resin production of this phenotype is good, but not as extreme as in the following 3 phenotypes. Flowering time: 75-90 days.

– NL/Haze phenotype: This phenotype shows more indica influence from the original Northern Lights, and therefore a smaller size, faster flowering and lower flower/leaf ratio.

It is also the most faithful to the characteristics of the original A5 Haze mother, producing rounded and very resinous flowers with a silvery appearance, which produces characteristic horn-shaped re-flowers at the end of flowering.

Incense, fleshy (liver) and organic (decaying flower petals) aromas. Flowering time: 66-80 days.

– Haze/Malawi phenomenon: Sativa dominant phenomenon and well balanced in terms of displaying the characteristics of the Haze A and Malawi parents. It produces huge and very dense buds, with an excellent flower to leaf ratio, with the shiny resin coating of our Malawi.

It produces light re-flowering in its final stages, although not as pronounced as in the first 2 phenotypes. Aromas of incense and woody Haze, with the oily and resinous background of Malawi. Flowering time: 75-85 days.

– Silverish Malawi phenotype: monstrous sativa phenotype with a major Malawi influence. Incredibly high flower/leaf ratio, very high production, with the classic huge trichomes and ovaries of our Malawi, and with a prodigious resin production that gives it an aggressive silvery appearance when ripe, taking the characteristics of the Malawi Killer phenotypes to extreme levels that rarely they have been achieved before. Flowering time: 75-85 days.

With these new projects, our priority will be to try and raise the bar of Sativa Haze breeding by crossing these old Dutch Haze elite clones with elite parents of our most worked sativa strains, and also in organoleptic terms, experimenting with different types of incense profiles by hybridizing the elite parents in this regard.
