Loud Sour by Loud Seeds

If you spend any time scrolling through the older grow forums, you know that finding a true, room-stinking Sour Diesel from the early 2000s is practically impossible these days. Enter Loud Sour from Loud Seeds. These breeders saw everyone crying about the death of real gas and decided to do something about it. They took their Original Loud—which is a killer cross of AJ’s Sour Diesel and Spicy Jack—and hit it with 7/8 Sour. The result is a heavily backcrossed love letter to the classic East Coast Sour D that will absolutely blow the roof off your grow tent.

This plant is not for rookies. She grows with that classic, lanky sativa structure, stretching like crazy the minute you switch your timers to 12/12. You’ve got to train her hard, use trellises, and snap those branches if you want to keep the canopy even. But if you put in the elbow grease, you are rewarded with light-green, foxtailing buds that absolutely reek of skunk, sour citrus, and sharp chemical cleaner. Guys who have popped these beans report finding phenotypes that make your eyes water just from brushing up against the leaves in week seven.

The community treats Loud Sour as a bit of a unicorn. People throw the word "loud" around loosely these days for anything that smells vaguely decent, but this strain is the literal definition of the word. The high is purely electric—a soaring, sweaty, heart-pounding rush that eventually tapers off into a relaxed, goofy haze. It’s exactly what the old heads are chasing when they complain that "weed doesn't smell like it used to." If you want to run something that brings back that nostril-burning pungency of the legacy market, this is the cut to hunt for.

Growing Loud Sour: 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 Original Loud or 78 Sour 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.
