Top 10 highest-yielding autoflowers - CannaConnection (2024)

If you’re looking for a high-yielding autoflower, it’s hard to go wrong with Auto Ultimate, a lovely, balanced cross of Auto Mazar and The Ultimate. Widely considered one of the highest-yielding autos in existence, this robust specimen is also easy to grow, making her a perfect strain for experts and novices alike. She also flourishes in all types of growing environments, developing plentiful, heavy, and very potent buds. Indeed, her flowers frequently grow to the size of golf balls and are absolutely covered with trichomes.

Auto Ultimate grows large, with a thick main cola surrounded by numerous side colas. This is why she generally needs help supporting her humongous flowers. Maxing out at 2m in height, Auto Ultimate can easily deliver up to 600g/m² indoors; and experts can rake in up to 1kg/m²! The only “downside” is that this auto takes anywhere from 12–15 weeks to go from germination to harvest, so a little patience is necessary.

Her smell and taste are equally satisfying, and often compared to both Lemon Haze and Lemon Skunk. Alongside a fresh, fruity, and spicy aroma, she delivers a high-octane effect that is both mentally stimulating and physically relaxing.

In a sea of autoflowers, this sweet indica-dominant gem delivers fabulous yields without taking up much space. The offspring of Mango and Big Bang Autoflower, Sweet Mango Autoflowering is easy and straightforward to grow, and entrances with her resinous, lime-green and rust-orange buds.

This strain does not reach great heights—maxing out at about 1m both indoors and out. As such, she makes a great candidate for SOG grows, as well as ScrOG. Impressive relative to her yield is her short seed-to-harvest time of just 9 weeks, which means you'll be enjoying her luscious buds in no time. Sweet Mango Autoflowering also produces very tiny leaves, making harvesting and trimming fast and easy. When all is said and done, indoor growers can rake in up to 700g/m² indoors, especially when growing in one of the aforementioned setups.

With an exotic, tropical flavour that is sweet, sour, and fruity, Sweet Mango Autoflowering produces a relaxing effect that soothes the body, stimulates appetite, and briefly takes the mind off the worries of the day.

Critical Neville Haze Autoflowering is a true find. A cross between Neville Haze Auto and Il Diavolo, this lovely sativa-dominant hybrid clocks in with a THC level of 21%.

She is also special on another front. Though 90% sativa, Critical Neville Haze Auto is perfectly suited for indoor cultivation, precisely because she doesn't grow into a monster. Reaching medium heights, even growers in more confined tents and rooms can give her a go. And she certainly comes through in the yield department, delivering 600g/m² indoors and 400g/plant outdoors, after an average of 11–12 weeks from germination to harvest.

Critical Neville Haze Auto produces long, wispy buds covered in trichomes, making this strain highly suitable for hash and concentrate creation. Her aroma and flavour are an equally lovely mix of woody spice and herbal mint that creates an almost sweetly metallic taste. The high is that of a classic sativa—talkative, energetic, happy, cerebral, and euphoric. The perfect wake-and-bake or socialising strain.

If you’re seeking a high-yielding autoflowering strain with a tropical twist, Pineapple Express Autoflowering is your baby. This indica-dominant hybrid is the result of crossing Pineapple Chunk with ruderalis, resulting in a tangy autoflowering wonder.

But what about her yields? Pineapple Express Auto is an anomaly here too, producing up to 600g/m² indoors and 100g/plant outdoors in just 10 weeks from germination. What’s perhaps most impressive about this is that plants rarely exceed 1m in height. So you can stay discreet while still raking in a satisfying harvest.

The effects of this tropical charmer are iconic of a soothing indica. She produces a strong, relaxing high mixed with just the right amount of uplifting euphoria. But unlike some heavy indicas, she won’t leave you lethargic after delivering her powerful punch. Pineapple Express Auto’s flavours are, unsurprisingly, a delight. As her name suggests, she develops sweet pineapple notes mixed with hints of other tropical fruits.

Cheese strains came to prominence in the 1990s rave scene, and have some of the most distinct profiles of any cannabis hybrid on the market today. They are frequently at the top of connoisseurs' lists for their distinct aroma and taste. This auto version of Royal Cheese will certainly make the grade.

Royal Cheese Auto may not impress in the height department, topping out at just 1 metre or so; however, her yields are more than satisfactory, particularly for an autoflower. When harvest swings around, after a relatively brief 10 weeks from germination to harvest, growers can expect to trim up to 475/m² indoors and 160g/plant outdoors.

This indica-dominant hybrid clocks in with 15% THC, making for a moderately powerful, but not overwhelming, high that will banish worries and give the muscles some time off. As for her aroma and flavour, veteran smokers will know what to expect; a dank, cheesy stench pervades the air when smoking, but the flavour is a bit sweeter and fruiter, making for a very pleasant experience.

A mild THC content of 12% makes this a perfectly light and relaxing smoke to power you through the day. However, given her satisfying body high, she is a nice low-key bedtime strain as well.
