Strain History(top)

Barney's Farm G-13 Haze is an award winning variety that crosses the legendary G-13 with Barney's Farm's favorite Hawaiian sativa. G-13 is a strain of mythic proportions because of its alleged origins in the experimental U.S. medical marijuana compassionate access program. This federal program provided medical cannabis to a small select group of patients. It started in the late 1970's, but when activists organized a flood of applications for HIV/AIDS patients to enter the program in the early 1990s, the government panicked and closed the program to new entrants.

Some have said that any government-grown weed could only be low-grade, but others insist that the government program's scientific approach resulted in the creation of a superstrain: G-13. Rumors circulated in the 1990s claiming that a G-13 clone had been smuggled from the grow facility. Shortly thereafter, breeders had backcrossed the G-13 into seed form and the name began to crop up all over the map. In the Barney's Farm cross, G-13 has been combined with a great tasting island sativa that has strong Haze influences in composition. Straight out of the gate, Barney's Farm G-13 Haze has a very nice smell of ripe fruit and Haze-sandalwood spiciness.

This variety is best compared with other stiva-dominant and Haze plants. In general, Haze hybrids require the vegetative time to be kept short. Flower forcing for this variety is recommended as soon as the clones have had a chance to establish themselves, which is helpful given that flowering times are fairly long, taking 10-12 weeks to ripen.

When vegged as directed, Barney's Farm G-13 Haze maintains a medium-tall stature with sturdy branches. This plant grows vigorously, and the flower structure has better density than many hazes, resulting in an above-average yield. The size and sturdiness of the plants also make it easier to grow in restricted indoor spaces than the typical Haze. The buds have a bit of sativa sponginess to them, but this plant likes to form one large main cola on the central branch. This tendency makes it ideal for a SOG garden, although SCROG is another good choice. Not only does G-13 Haze offer healthy yields with good THC levels, it also posesses intense aromas and flavors and a powerful cerebral smoke worth savoring. This variety encapsulates the winning qualities of flavor and high that many sativa lovers seek out, but maintains a bass note of indica that anchors the effects nicely.
G13 Haze is a legendary strain subject to much rumor and speculation. It has been proclaimed as the strongest strain ever created and some say it was genetically engineered by the US government in a secret CIA lab. Whether or not these rumors are true, there is no doubt that this is one of the strongest strains available today with very high levels of THC and buds glistening with resin. This hybrid of G13 has been crossed with an original Haze to give it a more uplifting high while still retaining the heavy hitting indica undertones. Bred for maximum potency and renowned for its medical use it's not for the faint hearted.
The legendary G-13 crossed with a Hawaiian Sativa doesn't mess about. A brief look into our history will explain why......G-13 was allegedly created by the Russians who focused on hybridizing different strains of cannabis in the 1970s. Supposedly, these organizations bred a strain of cannabis through hybridization that was more potent than any other. According to popular subculture was then liberated from a government lab in mississippi during the 1970's in order for breeders to clone and pass onwards. The G13 legend lives on with this remarkable G13 cross developed from the world famous G13 and our favourite Hawaiian Sativa. Stays short for a mostly sativa plant and has extraordinary density of flower structure with heavy resin production Ideal for SOG & ScrOG gardens. The effect is celebral yet powerful with a taste of fruit & spice.
