Type and genetics

The marijuana seeds G13 Haze Regular of Barney's Farm are the result of joining the indica G13 with a sativa from Hawaii owned by Barney's to get a sativa dominant productive and strong mental effect. A variety which reigned in the coffeeshops of the Dutch cannabis capital until a little more than a decade ago.


It has a vigorous hybrid-like growth with many long side branches. It adapts very well to all types of cultivation and all substrates. Outdoors it develops very well in Mediterranean climates with mild autumns, although rainfall should be taken into account.

Aroma and taste

It has a strong fruity pungent aroma with spicy notes. The flavor is intense, a fruit cocktail where citrus fruits are perceived together with caramel and spicy notes. A flavor that should be maintained by cultivating it with organic or bio-mineral fertilizers and stimulants.


G13 Haze Regular provides a powerful mental effect, which is stimulating, cheerful and enjoyable. An ideal high to stimulate the creative work, to delight in meetings with friends and to animate the playful or recreational activities. Suitable for use against stress or to lift the mood.


Flowering with large, dense, resin coated buds, it is a good producer of high quality buds used for a decade as a commercial strain. In rooms and closets, well cared for, it yields up to 550 grams per square meter and outdoors 600 g per plant grown in soil or in large textile pots.

Flowering in indoor cultivation

Grown under G13 Haze bulbs, it finishes flowering between 65 and 70 days after the appropriate vegetative phase. You can obtain very good results if you apply SOG (Sea of Green) or Scrog (Screen of Green) cultivation techniques.

Flowering in outdoor crops

Grown in natural light, G13 Haze Regular is ready to harvest from mid-October in the northern hemisphere and from mid-April in the southern hemisphere. If you use a plant support ring to support its branches, you will increase the production.
