Red Poison Auto by Sweet Seeds
Sweet Seeds really hit the nail on the head back when they dropped Red Poison Auto. They took their absolute workhorse, Green Poison, and banged it against a mystery purple autoflower that traces its roots back to some heavy Pakistani Kush. What came out the other side was a straight-up staple of the "Red Family" lineup. It's the kind of auto you can recommend to the guy running his first bucket in a closet, but it still pulls weight for veterans chasing bag appeal.
The visual show is mostly what keeps this strain in rotation. About 90 to 95 percent of the time, she'll drop those deep, bleeding red and violet hues right on the buds, and you don’t even have to freeze your room out to force the colors. She grows like a true hybrid, throwing up a chunky main cola with some wiry, flexible side branching that stretches up to four feet. And the smell? It's a loud, sticky fruit bowl dumped over a soft, old-school skunk baseline.
Over on the autoflower forums, you'll see people pulling down solid harvests in just about eight weeks from seed. A few old heads complain about variations in terpene expressions, but the colors are usually dead-on. When you factor in the sheer hybrid vigor and the frost rail she packs on by week six, it's pretty clear why Sweet Seeds used this gear to backcross and breed heavy hitters like Tropicanna Poison later on. It just plain works, and looks incredible doing it.

Growing Red Poison Auto: what to expect
Because Red Poison Auto is an autoflower it runs on age, not photoperiod: keep it under 18–20 hours of light from sprout to harvest, start in its final pot, and go easy on training after week 3 — autos never pause to recover. Growers familiar with Hindu Kush Indica or Green Poison 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.
