Glaucoma OG by Exclusive Seeds
When you start digging into the old-school OG heavyweights, Glaucoma OG by Exclusive Seeds is one of those elusive cuts that old heads still rave about. Rooted deep in the classic OG Kush family, this sativa-dominant hybrid (usually sitting around 60/40) was never babied into a feminized line. Exclusive Seeds only dropped this one in regular seed form, which meant you had to put in the work to hunt down a keeper mother. But man, if you found her, you were holding onto gold. It’s the kind of strain that earned its reputation purely through word-of-mouth on the old ICMag forums, long before Instagram hype dictated what we grew.
In the dirt, Glaucoma OG is a straight-up beast. She grows tall and bushy, stacking nodes that eventually swell into ridiculously huge colas. Some growers have literally pulled colas the size of basketballs off outdoor runs, which is absolutely insane for an OG-leaning plant. Indoors, she needs plenty of headroom and usually finishes up around the 60-day mark. The terpene profile is everything you want from a classic OG—aggressively loud, reeking of sharp pine, sour earth, and a chemical fuel burn that stings the nostrils in the best way possible.
Beyond just being a killer smoke, this plant became a legendary stud in the Exclusive Seeds stable. They used her to breed heavy hitters like Gas Can (crossing it with Flo) and Bocelli, passing down that signature branching structure and narcotic potency. The high itself is no joke; despite the sativa dominance on paper, it delivers a devastating, couch-locking body stone that melts away pain and anxiety. If you ever manage to track down a pack of these ancient regulars, pop them immediately—you're looking at a true piece of underground breeding history.

Growing Glaucoma OG: what to expect
As a sativa-leaning plant, plan for a big stretch after the flip (often 100–200%) — flip earlier than feels natural and keep training options ready. Sativa-leaning plants also generally prefer a lighter feed than heavy indicas. Growers familiar with Cataract 2 or Cataract 2 will recognize much of its behavior. Whatever the listing says, the cut in YOUR tent is the ground truth: log feedings, readings, and photos, and let the trends — not the label — drive decisions.
