G13 strain effects

The G13 marijuana strain contains approximately 70% sativa and 30% indica genetics. Its THC levels typically reach up to 24%, promising an abundance of psychoactive sensations. 

Many stoners consider G13 a super strain, and it doesn’t waste any time imparting its powerful effects. Within minutes, a rush of euphoria sends shivers down your spine, turning any frowns upside down.

Expect an instant mood boost that banishes negative feelings and completely changes your outlook on life. The G13 strain also induces focused, motivated, and productive feelings, but they don’t last too long because the physical sensations quickly swoop in.

As the indica influence takes over, your body starts to surrender to the limb-locking effects. A strong wave of sedation creates a mellow atmosphere, allowing you to relax and unwind.

These drowsy sensations typically cause couch-lock, so make sure you have a clear schedule before consuming the G13.

G13 strain flavors

The G13 cannabis strain emits a potent fragrance of dank earthiness, wild berries, and savory cheese. If you’re not used to the strong smell of cannabis, these buds might surprise you.

When you smoke the G13 strain, a woody, pine, and somewhat sweet flavor dominates your taste buds. Subtle traces of mint and other herbs leave a lingering aftertaste.

These marijuana plants reach about three feet tall and demonstrate a remarkable resilience to pests, pathogens, and mold.

You can raise them indoors or outside, depending on your available resources. Opt for a soil medium to boost the flavor profile or grow the G13 strain in hydro for explosive growth.

Outdoors, these weed crops flourish in awarm and dry Mediterranean-like climate, typically found in California, Australia, and Southern Europe. Indoors, remember to maintain dry growing conditions and keep the temperature around 64–84℉.

G13 strain genetics

Although the G13 strain’s history is mostly unknown, some clues point to its origin. Cannabis enthusiasts believe the initial G13 was a pure indica, but after decades of crossbreeding, it also contains sativa genetics.

The common theory is that the US government bred the G13 strain as part of a top-secret project. However, there’s no evidence to prove this is true, and nobody truly knows which cultivars played a part in its creation. Legend says an Afghani landrace could be one of the parent strains, but this information remains classified.
