Why you should buy G13 feminised seeds

G13 isn’t just a strain. It’s a damn legend. One of those names that carries a little weight and a whole lot of mystery. Government lab origins, top secret breeding projects, whispers of the “perfect” indica... no one really knows where the truth ends and the smoke begins. But one thing’s for sure: G13 hits. Hard.

If you’re after a compact, high-yielding plant that smells like old-school funk and berries mashed together in a skunky jar, you’ve found your girl. She grows dense, hits heavy, and doesn’t mess around. G13 is that strain you grow once, then again, and then keep forever in your rotation.

Strain Overview

Origin

Let’s be honest. No one knows the full story. But legend has it G13 was the result of a high-level breeding program tucked away in a US government lab. What were they trying to make? A bulletproof indica with knockout power and an easy structure. Somehow, one cutting made it out and found its way to the people. And we’ve been thankful ever since.

This version sharpens the package with a touch of secret hybrid genetics that boost structure and yield without sacrificing the stone.

Effects & flavours

This is pure indica territory, just how it should be. The high slides in gently, but before long you’re sunk into the couch, limbs heavy, face smiling, appetite wide open. Expect that blissful mix of physical calm and mental quiet. G13 doesn’t just ease stress. It erases it. Whether you’re zoning out to a film or letting the day fall away in silence, she always lands right.

The flavour? Funky and loud. It’s a burst of sweet berry with a deep earthy core, rounded out by skunky, woody notes that stick to your palate. It’s not shy and definitely not subtle, but if you like your weed to taste like something, she’ll keep you coming back.

THC & CBD Levels

With THC levels pushing up to 24 percent, G13 brings more than enough firepower. It’s potent but manageable, especially with a small buffer of CBD around 0.7 percent. That little bit helps soften the intensity and makes the whole ride smoother. The high is full-bodied, long-lasting, and gently euphoric without spinning you out.

Terpenes

This terpene profile has character. Valencene adds a citrusy depth. Alpha-pinene gives it that sharp, piney edge. And linalool smooths it out with a calm, floral undertone. The result is a rich, relaxing mix that hits the nose as much as the body. Classic, but not basic.

Growing G13 feminised Seeds

Grow Difficulty

This is a great all-rounder. New growers will appreciate her forgiving nature, while more experienced hands will love the consistency and yield. G13 stays compact, handles topping and LST well, and won’t flinch at minor stress. Plus, she’s naturally resistant to mould and fungi. If your conditions aren’t always perfect, she still shows up.

Indoor vs. Outdoor Growing

Indoors, G13 reaches around 31 inch to 39 inch. She stays short, bushy, and very manageable. Outdoors, you’ll see her stretch a bit to around 35 inch to 43 inch, but she never gets unruly. She performs beautifully in temperate, Mediterranean, and arid climates, and she handles greenhouses just as well.

Flowering Time & Yield

G13 flowers in 56 to 63 days. That’s a sweet spot for growers who want weight without waiting forever. Indoors, she produces around 1.8–2 oz per square feet. Outdoors, she brings in a generous 24.7–35.3 oz per plant when given plenty of sun and space. For a plant that stays compact, her output is genuinely impressive.
