Why you should buy G13 autoflower seeds

  • Delectable natural aroma and flavor

  • Powerful analgesic properties

  • Fast flowering due to the addition of ruderalis genetics

Growing G13 autoflower marijuana seeds (indoor/outdoor)

G13 autoflower weed seeds are suitable to grow indoors, outdoors, and greenhouses.

While outdoors, she prefers a warm climate; the addition of sturdy ruderalis genetics also allows her to thrive in cooler temperatures.

Once your seeds germinated (we recommend the glass of water and paper towel method combined), she has a brief vegetative stage. Her short flowering period is similar to that of the photoperiod feminized variant.

Since G13 loves a lot of nutrients, growing in a hydroponic setup is also an excellent option.

Make the most of your time and boost your yield by applying the Sea of Green method. You will be rewarded with a generous harvest in only 11 to 12 weeks!

Like all our autoflowering varieties, G13 autoflower are feminized seeds. This means they have been specifically designed to contain no male chromosomes, and your crop consists of 100% female plants.

Flowering time

The G13 autoflower seeds have a flowering time of 56 to 63 days before they deliver high-quality buds.

This brief vegetative phase and short flowering time allow the outdoor grower to realize multiple harvests per season!

Plant height

Her short, manageable size of only 90 to 110 cm makes growing G13 autoflower possible for every indoor grower, even those short on space.

With an outdoor grow, G13 autoflower cannabis seeds also grow into plants that rarely exceed 120 cm.

G13 autoflower yield

Despite her short stature, growing G13 autoflower is a highly rewarding cultivation.

With indoor yields of 450 to 550 grams per m² under optimal conditions, these petite high yielders will impress even the most discerning grower.

When grown outdoors, you can count on about 100 grams of G13 weed per plant.

Effects of the G13 autoflower strain

For a predominantly Indica strain, G13 offers surprisingly versatile effects. Users mention a slightly euphoric, Sativa-like, yet completely mellow high that instantly puts an end to any negative thoughts.

With this strain, chronic stress is now a thing of the past. Use her in moderation in a social setting with friends or curl up on the couch with a good book, while enjoying the soothing and relaxing effects on your muscle spasms or joint pain.

These analgesic properties also offer many benefits for medicinal use.

Are sleep disorders keeping you up at night? Try a slightly higher dose, and this super strain will send you off to a blissful night of sleep.

Side effects

Like with any potent strain with high THC, there can be some adverse effects. While usually limited to the frequently present dry eyes and dry mouth, novice users may experience dizziness or mild paranoia. In those cases, moderating dosage is key!

Smell and taste of G13 autoflower

The flavor profile consists of pungently earthy, herbaceous, and citrus aromas. A combination that will mesmerize the senses and pleasantly treat taste buds to a cocktail of delectable flavors and aromas.

This excellent taste and scent make smoking G13 weed a lot more appealing alternative to regular pain medication.

Origin of G13 autoflowering weed seeds

Although many species today have vague or mysterious backgrounds, few are the subject of as many Urban legends as the G13.

Tales of a rogue government agency scientist trying to create the ultimate medicinal strain from pure Afghani indica clones have been going around for decades.

These stories and her fantastic properties have contributed to her overall acclaim. Her rise to fame truly skyrocketed when the film American Beauty describes G13 as "extremely potent, but with a completely mellow high".

Whether there is any truth to these stories or not, G13 has one of the purest genetics the cannabis industry has ever seen, and the mysticism of G13 only adds to her appeal.
