Top 27 Highest Yielding Autoflowering Strains & Seeds: 2021

Autoflowering strains are an easy choice for anyone who wants an easy grow. These strains are normally crossed with cannabis ruderalis, which matures without waiting for natural light to reduce. Therefore, autoflower seeds are an easy choice for growing two crops in a season or for indoor growers who don’t want to bother with light restriction.

However, many autoflower strains have a lower yield. No matter how fast your crop grows, it’s obviously important to maximize yield. Choosing the highest yielding autoflowering strains can help. These strains have been bred specifically to maximize the size and quantity of bud.

*Note: these yields are estimates based on ideal circumstances. Actual yield depends on light, climate, soil, feed, and plant health.

Below we have outlined each high yield autoflowering seed in more detail. Note that strains are not ranked in any particular order.

1. Super Critical Auto

With an astounding up to 800g per square meter, Super Critical Auto might top the list of highest-yielding autoflower strains. It’s also one of the better autoflower strains to train, with good responsiveness to Sea of Green.

Additionally, Super Critical Auto is compact, less than 3 feet tall, and goes from seed to chop in just 8 weeks. However, for maximum yield, you’ll want to use strong lights and close to 18 hours of light per day.

Other than that, Super Critical Auto performs well in most climates, isn’t too picky about temperature unless it gets too hot, and requires relatively little special care. Make sure you feed her to get the best yield and otherwise, you’re good to go.

  • Flowering Time: 49 days
  • Hybrid (Indica / Sativa/ Ruderalis)
  • CBD Levels less than 1% (Low)
  • THC (Medium)
  • Plant Size: Small
  • Genetics: Super Critical (White Widow, Super Bud), Cannabis Ruderalis
  • Estimated Yield: 400-600g per square meter
  • Easy to grow
  • High resistance to disease and weather
  • Typical Effects: Relaxation, Uplifting, Sedative, Body high
  • Taste & Smell: Earth, Nuts, Skunk

2. Tangie Matic Auto

Tangie Matic Auto is a high yield autoflower strain with high THC production and fast flowering. That makes her a perfect choice for many growers.

While Tangie Matic Auto goes from seed to chop in just 9 weeks, you’ll likely see 450-650 grams per square meter indoors. That’s impressive, and her thick, sticky resinous buds are even more so. Growers get high yields of amber buds with little training, just prune the top leaves.

Tangie Matic also prefers high levels of feed. Make sure you buy nutrients and look for nitrogen heavy blends for the flowering stage for a maximum yield.

  • Flowering Time: 48-53 days
  • Hybrid (Indica, Sativa, Ruderalis)
  • CBD: Less than 1% (Low)
  • THC 23% (High)

  • Medium difficulty to grow
  • High resistance to disease and weather
  • Typical Effects: Creativity, Meditative, Body high
  • Taste & Smell: Herbal, Fruity, Tangerine, Cream

3. Girl Scout Cookies Auto

Girl Scout Cookies is famous for its flavor and yield, and the autoflower is no different. While lower producing than some of the other strains on this list, you can still expect up to 450g per square meter.

While Girl Scout Cookies is an autoflower, she can get relatively tall. However, with a total of 10 weeks grow time, you usually don’t want to train or prune too much. Instead, make sure you invest heavily in feed and light.

If you do, you’ll get big, heavy buds covered with sticky resin. And, because this strain gets big, a larger pot will mean a slightly larger yield.

  • Flowering Time: 56-70 days
  • Hybrid (Indica, Sativa, Ruderalis)
  • CBD: 1% (Medium)
  • THC 17% (Medium)
  • Plant Size: Medium
  • Genetics: Girl Scout Cookies, Cannabis Ruderalis
  • Estimated Yield: 400-450g per square meter
  • Easy to grow
  • High resistance to disease and weather
  • Typical Effects: Happy, Relaxed, Sleepy, Uplifting
  • Taste & Smell: Sugar

4. Gorilla Glue Auto

Gorilla Glue autoflower delivers Diesel genes with cannabis ruderalis for a production of up to 450g per square meter. This strain stands out as one of the stickiest autflowers, good for extracts and anyone looking for high THC.

While Gorilla Glue has a high yield, it will stay small at a maximum of 3 feet. It also does well in most environments, with good resistance to mold and weather. That’s to be expected, considering the mother strain.

In most cases, you should expect big center colas with good yields for side branches. You should keep pruning to a minimum though and focus on keeping the big top leaves down to let in more light.

  • Flowering Time: 55-65 days
  • Hybrid: (Indica/Sativa/Ruderalis
  • CBD: 1% (Medium)
  • THC: 26% (High)
  • Plant Size: Small
  • Genetics: Gorilla Glue, Cannabis ruderalis

  • Easy to grow
  • High resistance to disease and weather
  • Typical Effects: Relaxed, Happy, Uplifted, Energetic
  • Taste & Smell: Pine, Diesel, Earth, Herbal, Fruit

5. Stardawg Auto

Stardawg auto blends Chemdawg #4 with Tres Dawg to create a beautiful, high yield autoflowering strain. This intense green will deliver as much as 550 grams per square meter in as little as 2-3 months.

Impressive grow times aside, Stardawg Auto stands out for other reasons. For example, this strain stays tiny and grows well in 3–5-gallon pots. While you should use strong grow lights (in excess of 600 watts) for the best yield, growth is fast and consistent.

Additionally, this high yield autoflower will perform in most climates. As long as you deliver enough light and feed, you will get high performance out of it.

  • Flowering Time: 30-40 days
  • Hybrid: (60% Indica, 40% Sativa, Cannabis Ruderalis)
  • CBD: 1% (Medium)
  • THC: 22% (High)
  • Plant Size: Small
  • Genetics: Chemdawg #4, Tres Dawg
  • Easy to grow
  • Estimated Yield: 450-550 grams per square meter
  • High resistance to disease and weather
  • Typical effects: Relaxed, Happy, Creative, Euphoria, Cerebral high
  • Taste & Smell: Lemon, Pine, Diesel, Earth

6. Crystal Meth Auto

Crystal Meth auto is a fast-growing autoflower with yields of up to 600g per square meter. While ideal for beginners, unexperienced growers are likely to see lower yields.

Crystal Meth Auto delivers easy growth, a fast flowering period, and good adaption to most climates and weather. You will want to ensure she gets plenty of light. However, Crystal Meth will flourish with less light and fewer nutrients than some alternatives, although it is important to get the soil right.

Otherwise, you’ll have little to do but wait the 3 months for this beauty to finish flowering. Then, you’ll harvest 400-600g per square meter of rich, purple buds with THC averaging 20%.

  • Flowering Time: 53-63 days
  • Hybrid (Indica/Sativa/Cannabis Ruderalis)
  • CBD: 1% (Medium)
  • THC: 20% (Medium)
  • Plant Size: Small
  • Easy to grow
  • Estimated Yield: 400-600g per square meter
  • Genetics: Mexican landrace, Early Skunk, Trainwreck, Hawaiian landrace, Ruderalis
  • High resistance to disease and weather
  • Typical Effects: Cerebral high, body high, happy, energetic
  • Taste & Smell: Nuts, earth, Pine, berries, Citrus

7. Gorilla Glue #4 Auto

While the original Gorilla Glue Auto also uses the Gorilla Glue #4, this auto mixes Gorilla Glue #4 with Critical Diesel Auto for a unique strain. In fact, Gorilla Glue #4 Auto delivers 500g per square meter with citrus, diesel, and even chocolate tones.

Additionally, this strain is exceptionally easy to grow. However, you do want to make sure you keep this one dry, as it is fairly susceptible to mold. However, with an indoor flowering period of just 63 days, it’s relatively easy to do. Gorilla Glue is incredibly popular for flavor, with chocolate and bubblegum aromas, but you also get a big yield. Essentially, almost an ideal plant.

  • Flowering Time: 56-63 days
  • Hybrid: (Indica, Sativa, cannabis ruderalis)
  • CBD Less than 1% (low)
  • THC 15-20% (medium)
  • Medium difficulty to grow
  • Estimated yield: 500g per square meter
  • Genetics: Gorilla Glue #4, Critical Diesel Auto
  • Low resistance to disease and weather
  • Typical Effects: Cerebral, Strong, Body High, Relaxed, Creative
  • Taste & Smell: Citrus, Diesel, Pine, Sweet, Chocolate

8. West Coast OG Auto

West Coast OG blends the classic O.G. with cannabis ruderalis to create a high yield autoflowering strain. Like her mother strain, this beauty is a high producer, delivering as much as 650g per square meter.

Of course, to get that, you’ll want to use good lights, good feed, and some pruning. West Coast OG grows bushy for an autoflower, so it might be necessary to do some pruning to let light in. That makes this a good choice for light topping techniques. However, like most other autoflower plants, you’ll mostly want to leave her alone.

Otherwise, this strain will grow fast, big, and strong. You’ll get dense, big buds some 10 weeks after your original plant, for a fast, easy harvest.

  • Flowering Time: 53-63 days
  • Hybrid: Indica/Sativa/Ruderalis
  • CBD: 1% (Medium)
  • THC: 21% (high)
  • Easy to grow
  • Estimated Yield: 500-650g per square meter
  • Genetics: O.G. Kush, Cannabis Ruderalis
  • High resistance to disease and weather
  • Typical Effects: Calming, Relaxing, Euphoric
  • Taste & Smell: Citrus, Fruit

9. Amnesia Gold Auto

This autoflower version of one of the world’s highest producing Amnesia strains delivers on its heritage. Growers can expect as much as 600g per square meter indoors with little extra care.

Amnesia Gold delivers a beautiful, light green bud, coated with resin and gold trichomes. You’ll also get medium CBD and THC, for a balanced, soaring high. Plus, with intense citrus flavors and plenty of sugar, this strain delivers on flavor as well.

Like other Dutch-bred strains, Amnesia Gold Auto is relatively tolerant, highly resistant to mold, and has low care requirements. Give her enough light and this strain will perform.

  • Flowering Time: 65-85 days
  • Hybrid: Indica/Sativa/Cannabis Ruderalis
  • CBD: 1% (medium)
  • THC 15% (Low)
  • Easy to grow
  • Plant Size: Medium
  • Estimated Yield: 500-600g per square meter
  • Genetics: Lennon Haze/Amnesia Haze/Cannabis Ruderalis
  • High resistance to disease and weather
  • Typical Effects: Cerebral, Psychedelic, Relaxing, Uplifting
  • Taste & Smell: Citrus, Floral, Caramel,

10. Northern Lights x BBR

Northern Lights X Big Bud Ryder is an autoflower strain with a yield of up to 600g per square meter. This interesting crossbreed brings the high CBD and disease resistance of Northern Lights to Big Bud Ryder’s psychedelic high and big harvest.

With heights up to 4 feet indoors, Northern Lights X BBR is large for an autoflower. However, you’ll get large, frosty buds with unexpectedly dense trichomes. Use a larger container (10 gallons and up) to get a maximum plant size and maximum yield.

Some topping is beneficial. However, with a total grow time of just 2-3 months, you won’t have much time to train, so skip it. On the other hand, good feeding is very much appreciated by this strain, so invest in the nutrients.

  • Flowering Time: 45-55 days
  • Hybrid: Indica/Sativa/Cannabis Ruderalis
  • CBD: 1% (medium)
  • THC 22% (Medium)
  • Easy to grow
  • Plant Size: medium
  • Estimated Yield: 450-600g per square meter
  • Genetics: Northern Lights, Big Bud Ryder
  • High resistance to disease and weather
  • Typical Effects: Calming, relaxing, sedative
  • Taste & Smell: Lemon, pineapple, sugar

11. Northern Lights Auto

Northern Lights Auto is a reliable strain with consistent delivery. While she might produce less than some alternatives, Northern Lights Auto is a sure thing.

The autoflower is also incredibly versatile, you’ll see good yields even without a tent and lights. However, for maximum growth, you want both and good nutes. You’ll also have no trouble fitting this small, low odor strain in just about anywhere.

That makes this fast-growing strain an ideal choice for first-time and guerilla growers who want to keep their plant out of sight, without sacrificing yield.

  • Flowering Time: 38-42 days
  • Hybrid (Indica/Sativa/Ruderalis)
  • CBD Levels up to 1% (Low)
  • THC Levels 15% (Low)
  • Medium difficulty to grow
  • Plant Size: Small
  • Genetics: Northern Lights, Cannabis Ruderalis
  • Estimated Yield: 450-500g per square meter
  • Low resistance to disease, medium resistance to weather
  • Typical Effects: Strong, body high, calming, body buzz
  • Taste & Smell: Pepper, Spice, Fruit, pungent

12. Auto Mazar

Auto Mazar blends two of the world’s most popular Indica’s with Ruderalis into a single, high producing autoflower. This autoflower delivers yields of up to 480g per square meter of low THC weed.

While Auto Mazar doesn’t normally top 10% THC, growers love its smooth, intense physical effects. You’ll also get typical Indica highs with little psychedelics. Additionally, while Mazar’s yield is good, the plant often stays as low as 2 feet. That makes it easy to fit into tents and cabinets.

This, plus good disease resistance, temperature resilience, and fast grow times make Auto Mazar and easy choice if you want lower THC.

  • Flowering Time: 70 days
  • Hybrid: (Sativa / Cannabis Ruderalis )
  • CBD less than 1% (Low)
  • THC 10% (low)
  • Easy to grow
  • Plant Size: small

  • Typical Effects: relaxation, happy, sleepy
  • Taste & Smell: earth, wood, pine, citrus, diesel

13. Moby Dick Auto

Moby Dick auto is a high performing strain ideal for both indoor and outdoor growth. In fact, this is one of the better autoflowering strains to grow outdoors, providing you have plenty of sun.

Additionally, this strain is incredibly hardy. You’ll get a good yield no matter what the conditions. However, unlike most autoflowers, Moby Dick performs better outdoors, with up to 230 grams per plant. On the other hand, this is a very pungent plant, so it might not work outdoors.

That aside, Moby Dick Auto is an easy to grow plant. Use strong lights indoors on an 18–20-hour cycle, feed her, and prune the top leaves. You’ll get big, green buds with up to 17% THC.

  • Flowering Time: 75 Days
  • Hybrid: Indica/Sativa/Cannabis Ruderalis
  • CBD: 1.2% (Medium)
  • THC: 15-17% (Medium)

  • Typical Effects: Happy, Energetic, Uplifted, Relaxed, Euphoria
  • Taste & Smell: Earth, Citrus, pine, Wood, Mint

14. Critical Kush Auto

Critical Kush Auto, also known as Critical Rapido, is a blend of Critical Kush and BF Super Auto. This strain takes some time to flower but with an output of 500g per square meter, is well worth the wait.

In addition, Critical Kush is extremely tolerant. You can grow this plant with high yields in most climates. You’ll also get good output outdoors, although, like the previous strain, you’ll also get a lot of smell.

Otherwise, this incredibly short plant (sometimes as short as 1 foot) delivers well. You can also use low stress training with good results, as this autoflower takes more time to mature. Indoors, you want to focus on light for a higher yield.

  • Flowering Time: 70-80 days
  • Hybrid (90% Indica, 10% Sativa, Cannabis Ruderalis)
  • CBD: 1% (Low)
  • THC 15% (Low)
  • Easy to grow
  • Plant Size: Small

  • Estimated Yield: 550 g per square meter
  • High resistance to disease and weather
  • Typical Effects: Relaxed, Sleepy, Happy, Uplifted
  • Taste & Smell: Earth, Pine, Wood, Citrus, Herbal

15. Critical+ 2.0 Auto

Critical 2.0 Autoflowering crosses the original Autoflower Critical + back with Critical + for improved yield and THC. The new strain produces up to 550g per square meter, with thick, dense buds.

However, Critical + 2.0 isn’t as hardy as the original auto strain. You’ll have to keep her dry for a good yield. Additionally, you’ll want to stake or use Screen of Green methods for ideal output. Buds grow big, dense, and heavy, and her thin stems do snap during maturation. However, with a 70–80-day flowering period, you’ll have plenty of time for low stress training.

Otherwise, Critical + 2.0 Auto is easy, with little challenge. However, high resin buds mean trimming is a challenge.

  • Flowering Time: 70-80 days
  • Hybrid: Indica/Sativa/Ruderalis
  • CBD less than 1% (Low)
  • THC 15-20% (Medium)
  • Medium difficulty to grow
  • Plant Size: medium
  • Genetics: Critical + Auto, Critical +
  • Estimated Yield: 500g per square meter
  • High resistance to disease, low resistance to weather
  • Typical Effects: Relaxed, Happy, Euphoric
  • Taste & Smell: Citrus, Sweet, Floral, Fruity, Pine

16. Green Poison Auto

Green Poison Auto delivers sugar, fruit, and skunk buds, with yields up to 550g per square meters. However, most growers choose Green Poison Auto for incredible grow times of just 60 days from seed to chop.

While Green Poison Auto is a Green Poison clone crossed with Big Devil #2, you’ll get an entirely different smoke than Green Poison. However, with 15-20% THC, a smooth high, and exceptional resin production, that’s hardly anything to complain about.

Additionally, this fast-growing green strain is a beginner’s favorite. Give her good light and your weed will grow big, dense buds with little extra care.

  • Flowering Time: 28-42 days
  • Hybrid: Indica/Sativa/Ruderalis
  • CBD: Less than 1% (Low)
  • THC: 15-20% (medium)
  • Plant Size: Small
  • Genetics: Green Poison, Big Devil #2, Green Poison, Green Poison
  • Estimated Yield: 400-550g per square meter
  • High resistance to disease and weather
  • Typical Effects: Relaxed, Happy, Uplifted, Creative,
  • Taste & Smell: Sweet, Floral, Fruity, Citrus

 

17. Big Bang Auto

Big Bang Auto is an incredibly hardy strain ideal for growing outdoors or in winter. Despite a short stature of less than 2 feet, you’ll get a massive yield indoor with good lights.

Plus, with a flowering time of just 42 days, this beauty is an ideal choice for anyone looking for high production and high-quality weed. This wide, busy plant also performs very well in Sea of Green setups for more exposure to light and a higher harvest.

Big Bang gets her name from dense orange trichomes and a smoke that expands in the lungs, causing even experienced smokers to start coughing. Inhale with caution.

  • Flowering Time: 42 days
  • Hybrid: Ruderalis, Indica, Sativa
  • CBD: Less than 1%
  • THC: Medium
  • Plant Size: Small
  • Genetics: Skunk, Northern Lights, El Nino, Ruderalis
  • Estimated Yield: 400-900g per square meter
  • High resistance to disease and weather
  • Typical Effects: Calming, Relaxed, Happy,
  • Taste & Smell: Earth, Herbal, Floral, Pine, Diesel

18. Nevil Bilbo Auto

This tall autoflower makes a good choice for indoor or outdoor grows. In fact, with 500-600g per meter indoors and up to 300g per plant outdoors, it performs well in both.

In addition, Nevil Bilbo Auto is a tall plant. This autoflower strain can top 6 feet. However, size contributes to yield, with plants making good candidates for low stress training, Screen of Green, and Sea of green techniques.

While Nevil Biblo Auto is an easygoing plant, you’ll want a good light setup and hopefully a tent to keep humidity up. Otherwise, this Northern Lights Auto strain shows good genes and performs well in most conditions.

  • Flowering Time: 70 days
  • Hybrid: Sativa, Indica, Ruderalis
  • CBD: Less than 1% (low)
  • THC: Medium
  • Plant Size: Large
  • Genetics: Norhtern Lights Auto, Nevil’s Haze
  • Estimated Yield: 400-500g per square meter
  • Easy to grow
  • High resistance to disease and weather
  • Typical Effects: Energetic, Focus, Creative, Motivated
  • Taste & Smell: Herbal, Floral, Sweet

19. Pure Power Plant Auto

Pure Power Plant Auto blends a high production commercial strain with cannabis ruderalis, for a lower production but faster grow time. However, Pure Power Plant Auto is not at all predictable.

In fact, this autoflower ranges from 45-70 days flowering time, with outputs of 250-400 g per square meter. What she lacks in predictability, she makes up for in stealth. This plant is as much as 20% Ruderalis, making for a compact plant with few climate needs.

Additionally, you can choose almost any growing medium or setup you want. A grow room or tent provide the best yields, but you can choose outdoors or in a windowsill as well.

  • Flowering Time: 45-70 days
  • Hybrid: Indica, Sativa, Cannabis Ruderalis
  • CBD: Less than 1% (low)
  • THC: Medium
  • Plant Size: Medium

  • High resistance to disease and weather
  • Typical Effects: Energetic, Focus, Creative, Motivated
  • Taste & Smell: Herbal, Floral, Citrus, Woody

20. Pineapple Punch

For anyone looking for fruit, Pineapple Punch is one of the best autoflowers you can choose. Her rich pineapple and grapefruit tones are loved by growers everywhere.

While beloved for taste, Pineapple Punch also has a higher-than-average autoflower yield. Depending on care, you’ll get anywhere from 300-550g per square meter indoors. On the other hand, you likely don’t want this plant outdoors.

Pineapple Punch is a bushy plant that can move from seed to chop in just 80 days. However, that leaves little time for low stress training, but some will increase your yield. Otherwise, prune to ensure light gets to all the colas for maximum growth.

  • Flowering Time: 45-58 days
  • Hybrid: Indica, Sativa, Cannabis Ruderalis
  • CBD: Less than 1% (Low)
  • THC: Medium
  • Plant Size: Small

  • Taste & Smell: Fruity, Pineapple, Grapefruit, Sweet

21. Bruce Banner Auto

The Bruce Banner auto is a favorite, with up to 600g of production per square meter, huge trichome count, and up to 25% THC. While this beauty takes up to 11 weeks to harvest, you will get a payoff in rich orange trichomes laden with THC.

If high yield weren’t enough, the Bruce Banner Auto tastes good. She delivers a good mix of berries, sweet, and diesel, ideal for smoke or extraction. Trichomes are thin, crystal coated, and easy to smoke.

While Bruce Banner has a high output, you’ll get more with using a grow tent and good lights. Minimal training is required, as she grows too fast for most techniques.

  • Flowering Time: 35-49 days
  • Hybrid: 35% Indica/65% Sativa/Cannabis Ruderalis
  • CBD: Less than 1% (Low)
  • THC: 25% (high)

  • Taste & Smell: Sour, Earth, Floral, Herbs, Sweet, Berry

22. Wedding Cheesecake Auto

This incredibly fast strain goes from seed to chop in just 9 weeks, with 600g per square meter output. That’s impressive, considering her short stature and small pot needs.

Wedding Cheesecake is a classic, famous for rich flavors and high yield. This auto is even faster, with high resin production, good, sugary trim, and big sticky buds. High yielding side branches make her an excellent choice for Sea of Green. However, this does mean pruning and some stress training.

For maximum yield, grow Wedding Cheesecake Auto indoors in 3-gallon pots. Use nutrients, but flush heavily during the final 2 weeks.  Otherwise, this compact, low-smell plant is ideal for nearly everyone.

  • Flowering Time: 30-40 days
  • Hybrid: 35% Indica, 65% Sativa, Cannabis Ruderalis
  • CBD: Less than 1% (low)
  • THC: 22-24% (high)

23. Orange Sherbet Auto

This favorite delivers incredible flavors and up to 650 grams per square meter, making it one of the biggest yielding autoflower strains available. Additionally this is an extremely low maintenance plant, ideal for beginners.

However, this autoflower strain is relatively tall. At up to 5 feet, it’s not for those with limited space. On the other hand, busy growth make her ideal for Screen of Green and Sea of Green low stress training. That can be a good idea, as you will want to stake or trellis this beauty during flowering to prevent branches from snapping.

Orange Sherbet Auto goes from seed to chop in just 9 weeks. You’ll get huge, dense green buds and a plant packed with resin. That also means you’ll want to save the trim. This plant grows well outside in very sunny climates, otherwise, keep her indoors.

  • Flowering Time: 30-35 Days
  • Hybrid: 30% Indica, 70% Sativa, Cannabis Ruderalis
  • CBD: Less than 1%
  • THC: 24% (high)
  • Plant Size: Large
  • Estimated Indoor Yield: 500-650g per square meter
  • Easy to grow
  • Genetics: Orange Sherbet, Cannabis Ruderalis

24. Purple Punch Auto

This California autoflower delivers incredibly high yield and great growth. Plus, with high resin output, THC at 24%, and beautiful purple buds, it’s hard not to love this strain.

At the same time, you’ll want to give this beauty a lot of light. This means she works well outdoors on the west coast, otherwise you’ll want good grow lights. Otherwise, this fast-blooming, Indica-dominant strain is easy to grow.

Additionally, you definitely want to go easy on training, as this strain moves from seed to chop in as little as 60 days. Outdoors, you will likely get more yield, but make sure you have a good, sunny two months.

  • Flowering Time: 30-48 days
  • Hybrid: Indica, Sativa, Ruderalis
  • CBD: Less than 1% (Low)
  • THC: 18-24% (high)
  • Plant Size: large
  • Estimated Indoor Yield: 450-600g
  • Easy to grow
  • Genetics: Purple Punch, Cannabis Ruderalis
  • Typical Effects: Uplifted, relaxed, Creative
  • Taste & Smell: Sweet, Fruity, Cream, Earth, Berries

25. Zkittlez Auto

This Indica-dominant autoflowering strain yields up to 500g per square meter in as little as 3 months. You’ll also get massive, trichome covered orange buds on every branch.

While Zkittles AUto is easy to grow, you will have to stake her to prevent branches from snapping. She also responds well to Screen of Green and Sea of Green. However, you shouldn’t start stress training too early, as it will impact growth.

Otherwise, this high-trichome strain is short and a perfect stealth grow except odor can be high. Go heavy on the fertilizer and the water for the best yield.

26. Pineapple Express Auto

Pineapple Express auto is a top choice for new growers. With a 9-week cycle from seed to chop, good growth, and easy care, this strain has it all.

In fact, Pineapple Express Auto is famed for its “Christmas Tree” growth, allowing light to easily hit every cola with minimal pruning. That’s ideal for new growers who want something reliable. Plus, with 350-600g of yield after 65 days of flowering, it doesn’t get easier.

Pineapple Express Auto delivers big buds with thick THC coating the leaves and buds. You’ll also get a balanced high, with low THC and high CBD.

27. Blue Dream Auto

Blue Dream Auto is an easygoing plant with minimal care needs and high output. Her sativa-structure offers long internodes, perfect for light training.

However, with a quick grow period of just 80 days from seed to chop, keep training to a minimum. If you do, this beautiful purple strain will reward with plenty of dense buds and serious trichomes. Like Blue Dream, the auto version also adds on incredibly dense resin production, for an all-around high-quality plant.

In most cases, you won’t get blue bud out of an indoor grow. However, if you really want it, you can cool this strain down in the last few weeks of flowering to get incredible purples.

  • Flowering Time: 30-50 days
  • Hybrid: Sativa/Ruderalis
  • CBD: less than 1% (low)
  • THC: 18% (medium)
  • Plant Size: Medium
  • Genetics: Blue Dream, ruderalis

How to Attain the Highest Yield from Autoflower Seeds

Even the highest yielding autoflower strains can perform badly with poor care. On the other hand, with good care, you’ll see larger yields that improve as you learn how to grow your autoflower.

  • Light – Grow autoflowers indoors and invest in strong lights. 600-1000+ watts is ideal. Most strains will perform well with 18-20 hours of light a day.
  • Training – Don’t overdo it. Most autoflower strains just need to be left alone. They grow too fast to respond well to training.
  • Nutrients – Most autoflowers appreciate good nutrients, but many prefer significantly less than a standard strain. Pay attention to what you’re growing and feed accordingly.

Summary

Modern autoflower plants well exceed the strains of even a few years ago. That makes autoflowers an increasingly good choice, especially if you’re going for two crops or want a no-fuss indoor grow. At the same time, most autoflowering strains still produce less than photoperiod strains. These high yield autoflowering strains push the boundaries of that, with many outperforming photoperiod favorites.

However, any cannabis production depends on light, nutrients, and care. In the case of autoflowers, that means more light, good warmth, moderate nutrients, and plenty of water. Good luck with your grow.
