G13 Auto

Why you should buy G13 Auto seeds

G13 Auto isn’t some rushed autoflower with a flashy name and nothing to back it up. This is a properly tuned remix of an old-school legend: tight, fast, and properly powerful. It’s built for growers who want heavyweight results in a short cycle, without fussing over light schedules or stretching plants. And it delivers.

You’ve got the deep, calming weight of a 70% indica with the clarity and lift of a sativa just poking through. This one smells like walking through a wild herb garden, with berries on the breeze and a cheeky skunky note that sticks around just long enough to remind you she’s got history.

If you want no-nonsense cultivation with top-shelf results and a body high that wraps around you like a weighted blanket, G13 Auto is a solid pick.

Strain Overview

Origin

G13 is a strain that drips with mystery. Some say it came out of a classified government breeding program in the US back in the day. Is that true? No idea. Does it make for a better smoke? Honestly, kind of. Whatever the story, the original G13 earned its stripes by being outrageously potent.

With G13 Auto, breeders took that iconic genetic and added Ruderalis to the mix. The result is that same knock-you-out power, now wrapped in an autoflowering package that flips into bloom all on its own. No timers. No stress. Just big results, quickly.

Effects & Flavors

This one hits low and slow, and when it lands, it lands hard. Expect a euphoric onset that quickly sinks into full-body relaxation. It’s the kind of high that makes you forget what you were worried about and glues you to your favorite seat. You’ll feel calm, heavy, and a little floaty all at once. Perfect for late evenings or anytime you want your thoughts turned down and your body switched off.

Flavor-wise, G13 Auto brings a surprisingly complex profile. There’s fresh berry and sweet herbal upfront, with deeper woody notes and just enough skunky funk to earn respect from the old-school heads. It’s smooth, rich, and genuinely satisfying.

THC & CBD Levels

With 24% THC, G13 Auto is no lightweight. This is a proper heavy-hitter, but still surprisingly smooth if you’re not chasing couch-lock. The 0.70% CBD adds just enough body softness to round things out without dulling the edges. It’s potent, but not punishing.

Terpenes

The terpene blend here is a quiet killer. Borneol gives it that fresh, almost minty herbal top note. Terpineol adds something soft, slightly floral, and deeply relaxing. Together, they layer into the berry and wood to create something cozy, soothing, and seriously moreish.

Growing G13 Auto Seeds

Grow Difficulty

G13 Auto is beginner-friendly and low maintenance, but don’t let that fool you. This plant delivers dense, resin-rich buds even if you’re just starting out. It’s compact, forgiving, and built to thrive even with basic care. If you’re still figuring out your grow setup, this is one of those strains that helps you look like you know exactly what you’re doing.

Indoor vs. Outdoor Growing

She’s made for small spaces. Indoors, expect plants to stay between 90 cm and 110 cm. Easy to manage in tents, cupboards, or corners of a room. Outdoors, they’ll stretch just a bit more, hitting around 100 cm to 120 cm. Whether you’re growing in soil or coco, under LEDs or the sun, G13 Auto adapts well. She handles heat, tolerates a bit of dryness, and won’t throw a tantrum over the occasional mistake.

Perfect for balconies, backyard guerrilla grows, and greenhouses in [temperate], [mediterranean], [arid], or [tropical] climates. She’s hardy, stealthy, and quietly productive.

Flowering Time & Yield

From seed to harvest, you're looking at about 9 to 10 weeks total. The flowering stage itself wraps up in just 56 to 63 days, making G13 Auto a great option if you're aiming for speed. Indoors, yields range from 450 grams per m2 to 550 grams per m2. Outdoors, you can expect between 60 grams per plant and 100 grams per plant. Not record-breaking, but more than respectable for an autoflower of this quality. It makes up for any quantity with pure quality.
