G13 Haze Regular: Award-Winning Haze Genetics

G13 Haze is a regular, photoperiod cannabis strain bred by Barney’s Farm. This legendary Haze has been the winner of more cups than we can count due to its well-refined, Sativa-dominant genetic lineage and 24% THC levels. Those who enjoy easy-to-grow hybrid cannabis strains and consistently good results will love G13 Haze regular.

Excellent Sativa-dominant Hybrid

This strain is particularly useful for breeders who can use her to create their own unique hybrids which not only gives complete control over the grow, it also helps develop a deeper understanding of the growing process. G13 Haze grows to a medium height with a hybrid structure – the main branch with multiple side-branches – making it ideal for indoor growing. Indoor yields for this strain are 500 – 600 g/m2 while outdoor growers can bring in as much as 350 g per plant! Here is some further information to help you grow this strain:

  • Medium height – G13 Haze regular reaches a final height of 1.0 – 1.1 m.
  • Max EC of water – 1.1 in veg, up to 1.4 in flower.
  • Water pH; 5.8 – 6.0
  • Recommended lighting: Veg: 450 W CFL, Flower: 600 W HID.
  • Recommended nutrients: Age Old Organics 1GR4C Grow.

Classic Haze Smell And Taste

G13 Haze regular has a very characteristic smell and taste. Towards the end of flower, her large, dense flowers swell up and emit a sweet, pine-like aroma which slowly changes into a more complex smell as her terpene profile matures. Her hard-hitting Sativa effect is balanced very nicely with a relaxing, deep-body relaxation.

    • General impressions
      G13 Haze2 Regular harvested after 10 weeks (70 days) / yield: 238 G
      G13 Haze1 Regular harvested after 13 weeks (91 days) / yield: 277 G
      The G13 Haze is a dominant sativa with an enormous growth height and very long shoots.
      The phenotype is very different, while G13 Haze2 has a rather sour and sweet smell and hardly any colouring, G13 Haze1 has a tart smell and rich purple leaves.
      Indica and sativa effects clearly noticeable the sativa effect predominates naturally.
      It gets very big and you should think about it beforehand (earlier in the flowering, pruning, etc.) and in any case take enough earth 20L+. My recommendation for day and night suitable.
