Sour 60 Autoflower Overview: The 60-Day Speed Demon

You pop seeds in soil, flip on the lights, and 60 days later? A room full of frosty, aromatic buds ready to trim. That’s the magic of Sour 60 Autoflower, bred by the wizards at New420Guy Seeds (with roots in Mdanzig’s original crosses).

This hybrid beast blends Lowryder’s auto genes with Master Kush, Blueberry, and Sour Bubble for a balanced 40% indica / 40% sativa / 20% ruderalis profile that’s as sturdy as it is speedy.

From growing this strain on many occasions, Sour 60 has proven it’s no gimmick—finishing under 24/0 light with minimal fuss.

It’s short and compact (50-120 cm tall), perfect for SOG setups or stealth grows. Yield? Medium at 35-125g per plant outdoors, or 400-500g/m² indoors with good care. THC hovers around 12-18%, making it mellow yet effective, although I have had a few people tell me it was the most potent auto they had ever grown.

And the best part? Two killer phenos: the vibrant Purple and the cola-crushing Green Donkey Dong.

But why go auto in 2025? With rising energy costs and tighter spaces, these skip veg almost entirely, flowering at the 3 node. I’ve seen growers double-turn in a season, and trust me, that extra harvest is awesome. Plus, at Just Cannabis Seed, our seed packs guarantee high germination—80%+ guaranteed, most folks experience the + ;o)—and all my seeds ship free and discreet worldwide (if cannabis is legal where you live.)

Quick stats to geek out on: According to recent grower reports, Sour 60 clocks in at a reliable 60-day harvest, with 17.8% average THC for balanced effects.¹ It’s a favorite for beginners because, as one forum vet put it, “It’s forgiving—like training wheels for autos.”

Purple vs Green Pheno: Which Sour 60 Fits Your Grow?

Ah, the pheno hunt—my favorite part of any grow! Sour 60 throws two main distinct types, each with its own vibe. The Purple Pheno turns heads with its Kush-like hues, while the Green Donkey Dong (yep, that’s the name) goes all-in on one massive cola. Both from the same stable genetics, but choosing one can make or break your yield goals. Let’s compare ’em head-to-head, based on my runs and customer feed back.

From my experience, the Purple edges out for aesthetics—those violet nugs make killer Instagram shots and hold terps like a champ. But if you’re after simplicity, grab the Green; it’s like growing a single fat joint. Both phenos express around 50/50 in packs, so run 5-10 seeds to cherry-pick.

Pro tip: Cooler nights (below 20°C) amp up the purple—I’ve chased that color on purpose for fun, I love the purple cannabis.

Stats-wise, 70% of 2025 grower journals report Purple phenos yielding 15% more buds overall, thanks to better branching. However, Green fans swear by the “one-and-done” trim ease.

Purple Pheno Deep Dive

The Purple’s my personal fave for its showy side. (I have always been a sucker for the purple cannabis) Starting green, it blushes deep violet by week 6, thanks to anthocyanins from the Blueberry lineage. Expect compact structure (60-80cm) with 8-10 sites of dense, resinous flowers. In my last run, temps dipped to 18°C at night, and boom a purple overload. Flavor? That sweet-spicy berry hits different, mellowing into earthy calm.

Green Donkey Dong Deep Dive

Don’t let the name fool ya—this pheno’s a beast. The central cola balloons to 20-30cm long, dwarfing sides for a lollipop effect. It’s the speed king, can be ready at 55 days under LEDs, but I would say plan of 70 days.

I grew one in a 3-gallon pot last spring; harvested 65g of sticky green gold that smelled delicious. No need to top this auto.

Step-by-Step Growing Tips for Sour 60 Success

Alright, let’s get our hands dirty. Sour 60 is beginner-proof, but nailing these steps cranks yields and flavor. From seed to snip in 60 days? Here’s your roadmap.

1. Germination (Days 1-3): Soak in RO water for 12-24 hours till they sink, then paper towel method at 24-26°C. 90% pop in 48 hours.
2. Seedling Stage (Days 4-14): Transplant to 1-gallon (at least) pots with light soil mix (FoxFarm Ocean Forest rocks). 18/6 light at first, then ramp to 24/0 by week 2. Keep humidity 70%, temps 75-80 F. Watch for stretch, I don’t generally top this strain, as they usually finish under 2 feet.
3. Flowering (Days 15-45): No flip needed; she autos right in. LST gently for even canopy—I’ve doubled light penetration this way. Nutes: Half-strength veg formula weeks 2-4, bloom boost after. pH 6.0-6.5.
4. Late Flower & Harvest (Days 46-60): Flush week 8 with plain water. Trichs 70% milky? Chop. Dry at 18-21°C, 50% RH for 5-7 days. I like to cure in jars, be sure to burp until the moisture is low enough and stabilizes.

For Purple phenos, cooler finishes (18°C nights) lock in color; Greens love heat for cola swell. Outdoors? Plant March-June for summer solstice glory.

Yields hit 100g+ in my greenhouse with these tweaks. And remember, always check local laws before starting—I’m all about responsible growing.

• Lighting: 250W LED minimum; 24/0 maximizes speed.
• Soil vs Hydro: Soil works great (forgiving); hydro ups yields 20% but demands more knowledge/work.
• Pest Patrol: Sour 60 resists pests in my experience, but always be observant.

Common Mistakes and How to Avoid Them

Mistakes can be made, but I have found this strain to be a vigorous grower (less time for issues) , and very forgiving.

• Mistake #1: Overfeeding Early. Autos like Sour 60 burn easy—start at 1/2 strength.
• Mistake #2: Ignoring Pheno Signs. By day 10, Purples show red stems, you can see what’s up early.
• Mistake #3: Poor Airflow. Dense colas invite mold. Fans on low, 40% RH late flower. Prevention is #1, rather then treatment.
• Mistake #4: Harvesting Too Soon. Wait for 60 days; pistils 50%+ brown. It is quick, but give her time.
• Mistake #5: Skipping Cure. Dry is step one; 2-week jar burp unlocks terps.

Effects, Flavors, and Medical Benefits

One toke of Sour 60, and you’re lifted: a gentle cerebral buzz meets body calm, like floating on a berry cloud. At 12-18% THC, it’s mellow—perfect for daytime without couch-lock. Purple leans relaxing (indica kiss from Blueberry), easing stress and pain.

Flavors? Divine. Sweet bubblegum base with sour lemon twist, exhaling to earthy pine and overripe blueberries. Terps like myrcene (calm) and limonene (uplift) dominate—lab tests show 1-2% total. Medical angle: Great for chronic stress (70% users report relief), PTSD, insomnia, and appetite loss.

Effects timeline: Hits fast, peaks at 30 mins with happy haze, fades to chill after 2 hours. No paranoia—ideal for mixed crowds. Always start low, especially if new.
