KGB by Vanc. Island SC
If you were smoking out in the Pacific Northwest back in the late 80s, you already know the name. KGB, or Killer Green Bud, started as pure street slang to separate the good indoor hydro from the brick weed flooding the market. But the crew at Vancouver Island Seed Company (VISC) eventually took that legendary moniker and stamped it onto a very real, very heavy strain. They crossed a heavy-hitting Afghani Hybrid with a Burmese Hybrid to create an absolute sledgehammer of an indica. It was only ever released as regular seeds, so finding a true cut nowadays means hunting through old seed stashes and preserving your favorite mother plant.
In the grow room, KGB acts exactly like the old-school indica it is. The plants stay relatively short and bushy, pumping out dense, pale green buds covered in bright orange hairs. You're looking at roughly 53 days in flower before she's ready to chop. She takes well to topping and training, but honestly, you can just let her run natural and still pull a solid harvest. The resin production is ridiculous, making the trim job a sticky, scissor-jamming nightmare in the best way possible. The smell in late flower is all spice and herbal funk, grounded by deep, woody earth tones.
When it comes to the smoke, KGB is the definition of a creeper. You might take a few pulls and think it's a smooth, clear high, but give it ten minutes and your legs will feel like they're made of lead. It's a heavy, narcotic stone that seasoned smokers used to hunt down for serious pain relief and insomnia. The flavor matches the nose perfectly—lots of spicy caryophyllene that coats the mouth. Just be careful when hunting down modern clones; a lot of dispensaries slap the KGB name on random new crosses, but nothing beats that original VISC Burmese/Afghani slam.

Growing KGB: what to expect
As an indica-leaning plant, expect a modest stretch after the flip (roughly 50–100%) and dense bud structure — which makes late-flower humidity discipline the main risk: keep RH in the 40s once buds fatten to stay ahead of mold. Growers familiar with Afghanistan Hybrid or Burma Hybrid 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.
