Looking for a knockout indica with serious weight behind it? G13 delivers heavy yields, sky-high potency, and that unmistakable old-school funk in every sticky, berry-flavored bud.
G13 has a reputation that borders on the mythical, and not without reason. This is one of those strains that comes wrapped in enough conspiracy lore to make a stoner’s head spin. Government lab origins? CIA experiments? Who knows. What we do know is this: G13 slaps. It’s a powerhouse indica that hits hard, grows steady, and rewards patience with buds that smell like trouble and smoke like silk. If you’re looking for a no-nonsense heavy-hitter that practically oozes old-school cool, G13 is a serious contender.
So here’s the tale. Back in the day, some hush-hush government program was supposedly cooking up the "perfect" indica. G13 was their pride and joy. High potency, minimal stretch, stone-you-into-the-floor type of stuff. Then one of the cuttings mysteriously found its way out into the wild. Accidental? Intentional? Doesn't matter. It happened. And honestly, thank whatever higher power you believe in because this strain deserved freedom.
G13 leans heavy on the indica side, and you’ll feel it the moment it kicks in. It’s a body-melter. One of those strains that quiets everything: your muscles, your mind, your stress. Expect a big exhale followed by a slow-motion slide into the couch. And if you were thinking of doing anything productive, maybe think again.
Flavor-wise, it’s deep, earthy, and herbal with a slightly sweet finish. Pungent but in that “yes, this is going to wreck me in the best way” kind of way. It’s not flashy. It’s not fruity. It’s straight-up dank with an old-school backbone.
Clocking in around 22% THC, G13 hits that sweet spot between “strong enough for seasoned heads” and “manageable if you don’t overdo it.” It’s got just enough CBD, about 1%, to round off the edges a bit so the high feels smooth rather than sharp. But make no mistake, this one still packs a wallop.
The terp lineup is stacked with caryophyllene, myrcene, humulene, and limonene. That means you're getting a nice blend of spicy and herbal notes with earthy sweetness and a whisper of citrus lift. Myrcene does the heavy lifting on the sedative side. Caryophyllene adds warmth and body. Humulene brings in that subtle hop-like bitterness. Limonene sneaks in to lighten the mood just before the full-body melt kicks in.
G13 doesn’t throw tantrums. It’s a steady grower with no drama, and doesn’t need you fussing over it 24/7. Perfect if you're still finding your feet as a grower, but even the pros keep this one in rotation just because it’s so damn reliable. She stays compact, bushes out nicely, and responds well to a little topping or LST if you’re into that kind of thing.
Indoors, G13 is right at home. Doesn’t stretch much, so height won’t be a problem. She typically grows to around 80 cm to 120 cm, which makes her easy to manage in tighter grow tents or cupboards. Outdoors, she can stretch her legs a bit more, reaching up to 130 cm to 170 cm under full sun. She handles Mediterranean and temperate climates well and doesn’t mind the occasional dip in temps. Just keep her dry in the final weeks if you’re in a wetter region.
Expect flowers in around eight to nine weeks, typically between 56 and 63 days. Indoors, yields fall in the range of 400 to 500 gram per m2, and if you treat her right outdoors, she’ll give you 500 to 600 gram per plant without much fuss. She's compact but efficient, and the harvests are more than worth the wait.
You don’t get a name like G13 and stick around for decades unless you’ve got the goods to back it up. This isn’t trendy. It’s timeless. If you want a strain with character, weight, and a bit of that forbidden fruit vibe, grab a pack of G13 Feminized seeds from WeedSeedsExpress. Discreet shipping, germination guarantee, and real-deal genetics every time. Grow it. Smoke it. Pass the legend on.
