HP-13 by Clone Only Strains
HP-13, or just "The P" to anyone who was slinging it in New York back in the day, is straight-up underground legend status. This clone-only monster was heavily guarded on the East Coast and in NorCal for decades. Everyone argues about the lineage on ICMag. Some swear it's a pure Afghan that came over during the hippy hashish trail days, while others are convinced it's a Hash Plant #13 selection mixed with G13. Either way, this cut commanded ridiculous tickets back when it was peaking.
Growing the original cut was a serious headache. She was notoriously prone to powdery mildew and didn't yield much, producing these incredibly ugly, bumpy, resin-caked nugs. It’s got a face only a mother could love. But man, the smell is out of this world. It reeks of garlic, black pepper, burning rubber, and straight mothballs. That acrid, chemical funk sticks to your fingers for days.
Luckily, breeders like CSI Humboldt stepped up to preserve the legacy, making S1 seeds so the rest of us could run her without needing to hunt down a golden ticket. When you smoke her, it’s an absolute sledgehammer. Pure couch-lock euphoria that drops you into a heavy, giggly trance.

Growing HP-13: 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 Indica 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.
