G13 Autoflower Origin and Genetics

G13 Autoflower carries a legacy steeped in cannabis lore and genetic prestige. This strain owes its origins to the legendary G13, a strain rumored to have been secretly developed by the U.S government during the 60s and 70s. It later underwent a fortuitous union with a resilient Ruderalis strain, birthing this robust autoflowering variant. The potent indica characteristics of G13, coupled with the autoflowering nature inherited from Ruderalis, allow this strain to thrive in various climates, making it a versatile selection for cultivators and connoisseurs alike. Its influential lineage has played a pivotal role in developing numerous modern-day hybrid strains, cementing G13’s place in cannabis history.

How to Grow G13 Autoflower

Cultivating G13 Autoflower seeds is an exciting journey, one that is forgiving for novice growers while still engaging for those with more experience. This hardy strain thrives both indoors and outdoors, owing to its strong Ruderalis genetics. It prefers a mild to warm climate but can also adapt to cooler environments thanks to its inherent resilience. Nutrient-wise, G13 Autoflower flourishes with a balanced diet of nitrogen, phosphorus, and potassium, with occasional cal-mag supplements to support its vigorous growth. This autoflowering variant speeds through its life cycle, reaching maturity around 8–10 weeks post germination. Despite its quick growth, don’t be fooled — G13 Autoflower is no lightweight when it comes to yield. Expect bountiful harvests, with indoor yields averaging around 500–600 grams per square meter, and outdoor yields offering a generous 5–15 ounces per plant. Cultivate with care, and G13 Autoflower will generously reward your efforts with a stellar, potent harvest.

    Yo, these G13 Autoflowers are straight fire! Planted em and boom, like clockwork, they grew into these lush buds in no time. Super easy for a beginner like me. And the buds are legit strong, stoned vibes all the way. Definitely gonna grow these babies again!

  2. Kyle T.

    Super impressed with G13 auto. Got some great yields and the quality is top shelf. Buds are dense, sticky and bursting with flavor. Hits nice and smooth with a strong kick.

  3. John D.

    Amazing! Grew G13 Autoflower this time around and it’s the best I’ve had in years. Fast grow, lots of dank buds, it’s just what I needed. Highly recommend to any grower out there looking for a reliable autoflower strain.

  4. Shane N.

    The G13 Auto strain really served me well. It yielded massive, densely packed buds that were as frosty as they were terpy. The colors in flowering were stunning and the aroma is loud. It has a sweet weed smell with a hint of a gas.

  5. Kevin M.

    Just finished my first round of G13 autos and I gotta say I’m impressed. Seeds popped up fast and grew steady without fuss. Didn’t need to baby them like some other strains I’ve tried in the past. The yield was solid and the potency slaps! Definitely a repeat purchase on the horizon. Good job on these genetics!

  6. Sam B.

    Placed my order and received my seeds just a few days after. Happy they didn’t ship thru customs, my package shipped from California. I’ve already germinated the seeds and there were no issues with any of them. They are currently thriving indoors under LED light, I keep them on 24 hours and they seem to love it. Got my fingers crossed for a good harvest!

  7. Beau R.

    Finallyyyy got hands on G13 autoflower seeds and the harvest blasted through all my expectations. Full package, they deliver on quality AND quantity. Rapid growth cycle – these gals have the true autoflower spirit, super fast, couldn’t believe they started flowering so soon. The buds, oh the buds! They’re dense, fat, and glistening, heavy on that THC punch. You will feel this one, no doubt! For anyone starting out growing, G13’s hassle free. Gives out a generous yield in no time. Highly, HIGHly recommend!

  8. David C.

    I recently tried growing out G13 autoflowering seeds and I gotta say, they were worth every penny! The seeds germinated really quickly and the plants grew dank buds in barely any time at all. To be honest, I was skeptical about autoflowers as I’ve never grown them before but these turned out to be super potent and amazing quality.
