Best Autoflower Seeds: High Yield Autoflower Strains [2024] 2

Autoflowering strains are becoming increasingly popular and for a good reason. They grow relatively short without training, bring fast harvests, and are usually easier to grow than their photoperiod counterparts. This post is Paramount Seed Farms’ list of the best high-yield autoflower strains and the best autoflower seeds.

Autoflower strains are great plants to learn to grow, but some still contend they aren’t worth the trouble because of low yields and potency.

Highest Yielding Autoflower Seeds – Highest Yielding Autoflower Strain Table

If these misunderstandings were genuine, we would never bother with autoflowers, but we will continue searching for the next ‘gem’ in our stable of autoflowers.

Autoflowers are always in our indoor rotation, and when it comes to the season, we dedicate a large portion of our outdoor garden to autoflowers because we know we can get at least two harvests in before the ‘Big Ones’ are done.

Yes, you aren’t going to pull down 2000g from a single outdoor autoflower, but as most experienced growers know, it is all about efficiency. With as little space and resources as possible, get the most out of a plant, yielding and potency.

Achieving 200g+ from an autoflower strain outdoors is not out of the question, not to mention it will probably be ready to harvest in less than 9 weeks!

Below is our running table of the best high-yield autoflower strains available on the open market.

*These are the results of our actual testing. Conditions were ideal, and we have also tested 44 autoflowering strains.
*All of our tests were done using Gen Hydro Flora Series Nutrients. Each plant was grown in its own 5-gallon DWC system; conditions were ideal, with no added CO2, and under a Mars Hydro LED Grow Light in a 4×4 grow tent, 3 plants per tent.

White Widow XXL Best Autoflower Seeds

White Widow XXL

Best of the Best – One of the Best Autoflowering Strains

The White Widow XXL Autoflowering strain of marijuana is Indica-dominant and was created by crossing a White Widow Auto with Dinafem’s elite clone of its photoperiod White Widow. It is a third-generation auto-flowering plant that takes only eleven weeks from seed to harvest. This strain produces generous yields of hard, resin-covered buds with relatively few leaves, making trimming a breeze once the buds have dried. It can be grown indoors, outdoors, and in greenhouses, with the latter being especially useful in cooler regions for extending the growing season. Dinafem recommends adding one-third coco coir to a soil mix to increase plant metabolism and speed growth. Indoor plants will produce 400-450 gr/m2 yields in a total grow cycle of 80 days, while outdoor plants will yield between 60-170 gr each from April to October. The floral smell and bitter-sweet taste of this strain make it unique. Its high THC production gives a powerful yet soothing effect that lasts a long time, and it has claimed therapeutic benefits for countering stress.

Tangie Autoflower - Best High Yield Autoflower

Tangie

Tangie Matic is an automatic Sativa-dominant plant, meaning it flowers on its own. This strain can produce up to 23% THC. The Tangie clone used to create this strain was obtained at a cannabis-related event in California, and it was then turned into an auto-flowering strain by the Fast Buds breeders. If you plan to grow Tangie Matic outdoors, be aware that it can grow up to 150 cm tall, which could attract unwanted attention. This plant is not well-suited for training, as any stress during its vegetative stage could harm it. With proper care, Tangie Matic can produce 450-650 grams per square meter or 50-350 grams per plant after 9 weeks from the seedling stage. Tangie Matic has a refreshing fruity scent with tangerine flavors when smoked during cultivation. The effect is a cerebral high that eventually turns into a body stone. After 30 minutes, tensions and stresses will fade, and creativity will be enhanced while maintaining lucidity. Tangie Matic is highly recommended for therapeutic use, especially for people experiencing migraines, anxiety, depression, chronic stress, and appetite loss. It is an excellent strain for morning/daytime use, especially for medical purposes.

Sour Stomper Autoflower

Sour Stomper

This is an example of what can be achieved through careful breeding. Auto Sour Stomper is a 50/50 hybrid of Indica and Sativa, created by crossing a Sour Crack female plant with a Grapestomper OG male plant from Gage Green. Mephisto Genetics then transformed it into a fully-automatic strain. Auto Sour Stomper grows like an Indica, maintaining a low profile until the flowering stage, when it can grow up to four times taller, displaying its OG background. With plenty of budding sites, low foliage density, and an open structure, buds can maximize their growth and density, leaving popcorn buds in the past. The plants grow well indoors, outdoors, or in a greenhouse, reaching a height of 80-120cm and yielding 120-150gr/plant in 65-70 days from germination. The buds are incredibly resinous, making excellent extracts or hash, and the leaves turn shades of blue and purple in cooler temperatures. The grapey aroma and flavor, with a bit of funk, make it a real feast for the senses. Its effect is a feel-good high, perfect for good vibes.

Ripleys OG Autoflower

Ripley’s OG

Mephisto Genetics has put much effort into discovering and developing the finest auto-flowering strain. After experimenting with various renowned and elite seeds and cuts, they were captivated by two strains, Triangle Kush and Alien OG, which were produced from a vast collection of Cali connection stock. Alien OG is a short, stocky plant with thick, lush leaves, dripping resin, and rich, deep, autumnal colors. The plant turns purple, almost black, in late flowering, with slightly cooler night temperatures. The initial yield was impressive for an OG, and when grown consecutively, it produced very dense, juicy buds of the utmost quality. For the autoflowering match, Mephisto Genetics went for a larger-sized plant with a Sativa-dominant profile. This attribute carried forward into Ripley’s OG as it developed over successive generations, which opened up its structure, averaging 110cm tall, making it one of their tallest varieties. The yield is excellent, and well-cultivated specimens can produce up to 120g/4oz per plant with a good life and environment.

  • Variety: Indica / Sativa
  • Flowering: 70 days
  • Yield: 120 g/plant

How To Increase Autoflower Yield

  • Select high-yielding auto seeds (obviously) – the list above is a good start, as well as only choosing reputable auto breeders.
  • Start your autoflower plants in their final pot. No transplanting!
  • Add nutrients at 50% strength after you seed two sets of true leaves. Increase strength by 10% every 5-7 days, depending on growth/drinking. Consult the autoflower feeding schedules to ensure optimal feeding. DO NOT OVERWATER!
  • Choose hydroponics or coco as your method/medium. If growing in soil, use fabric containers rather than traditional pots or buckets. Fabric containers will give your autoflower plants more air/oxygen, leading to larger yields.
  • Do not feed nutrients at too high of an EC in pursuit of larger yields. Nutrient burn will stunt their growth and lead to disappointing yields.
  • Switch to using LED grow lights. Since switching from HPS to LED, I have seen my auto yields flourish.
