Sour Diesel Auto doesn’t tiptoe in. It storms the grow room with that eye-watering tang of sour fuel and a heady sativa blast that made the original a legend. Only now, you get it without the drama. No light cycles. No stretching for weeks. No fuss. Just plant it, keep it happy, and in around two months, it’ll slap you with that unmistakable diesel punch and a grin you can’t shake.
This isn’t just a quick version of a classic. It’s a clever rebuild. Same electric energy. Same mouth-watering funk. But with the fast, no-nonsense attitude of a true autoflower. For first-timers and seasoned growers alike, this one earns its place in the tent.
After bigger yields and a little more control over training and timing? Our Sour Diesel photoperiod version gives you room to dial everything in.
Sour Diesel Auto was bred from two absolute bangers: Chemdawg 91 and Super Skunk, with a little ruderalis in the mix to get that auto timer ticking. Chemdawg brings the cerebral chaos. Super Skunk lays down some of that funky backbone. The result is a strain that’s all attitude, all flavour, and somehow still easygoing to grow. It’s like getting a high-octane sports car that doesn’t mind a bit of dirt on the wheels.
Right out the gate, this one hits you with a sharp, citrus-soaked lift and a grin that creeps up fast. Euphoric. Electric. The kind of buzz that makes you want to clean the house, call your mates, or disappear into a sketchbook for hours. Not a sleepy strain, that’s for sure.
The flavour? Loud. Properly loud. Diesel, lemon rind, earthy herbs, and that skunky twist that stings the nostrils. It's got a tang that sticks around. And if you’ve ever cracked a jar of Sour D, you know exactly what we’re talking about. It’s the kind of aroma that makes neighbors suspicious and smokers nostalgic.
With 23% THC, you’re not getting a mellow afternoon nap out of this one. It’s potent, no doubt. But not overwhelming if you know your limits. The 0.7% CBD gives it just enough smoothness to stop it from going into jittery territory. Still, this is a strain that wants you up and moving.
This one’s terp game is proper stacked. Limonene leads the charge with that citrusy uplift. Beta Caryophyllene brings a peppery edge that sits nicely in the chest. You’ve also got Alpha Pinene for a bit of forest freshness, Camphene and Beta Farnesene for some subtle herbal spice, and Terpinolene, which always keeps things interesting. Alpha Bisabolol? That’s the secret smoothness. Altogether, it’s like a diesel-soaked lemon grove with a dash of pine cleaner and just enough funk to keep it honest.
Sour Diesel Auto might sound intense, but she’s actually pretty chill when it comes to growing. Perfect for beginners. You won’t need to wrestle with training or stress about flipping lights. It just does its thing. Plus, with solid fungal resistance, you don’t have to hover over it like a paranoid parent. Give it light, a decent breeze, and some basic care, and it’ll repay you with top-shelf nugs and that room-filling funk.
She’s compact enough to fit in tight indoor spots, usually around 75 cm to 100 cm. Give her some space and sunshine outdoors and she can stretch up to 160 cm without getting lanky. A good pick for greenhouses too, especially in Mediterranean and temperate climates. Whether you’re running LEDs in a cupboard or planting in pots on a balcony, she’ll adapt without throwing a tantrum.
Sour Diesel Auto finishes fast, with a flowering window of 56 to 63 days. That’s seed to harvest in about two and a half months total. Indoors, expect yields between 350 grams per m2 and 400 grams per m2. Outdoors, you’ll typically see between 50 grams per plant and 170 grams per plant if conditions are right. Not the biggest yielder on Earth, but with buds this potent and loud, you won’t be complaining.
If you want something fast, potent, and unapologetically loud, Sour Diesel Auto is ready to roll. It’s a classic reborn for growers who want more time enjoying the smoke and less time fiddling with timers.
