Top 10 Highest-Yielding Outdoor Autos

If you’re going to grow autos outdoors, it makes sense to opt for cultivars that offer the best bang for your buck. Below, you will find a detailed review, week by week, of our top 10 highest-yielding auto strainsthat are perfectly suited for outdoor cultivation. Along with their effects, you will gain insight into what to expect during each stage of the growing process.

White Widow Automatic

White Widow Automatic pairs rapid growing times with a mellow high and earthy flavour. You can start seeds indoors anytime. Outdoors, once all risk of frost has passed, sow seeds directly into their final pot indoors for the best germination rate.

Once seeds have sprouted, place your pot in your chosen outdoor growing location. Expect a vegetative phase of four weeks; your plants will reach a height of around 40cm during this time and develop a dense and luscious canopy. Switch to a feed containing higher levels of potassium and phosphorus and watch your plant stretch to around 110cm during bloom. Prepare to harvest your mature flowers following a flowering time of 7–8 weeks.

As an autoflowering version of White Widow, this strain's ancestry makes her one of the best outdoor autoflowers. She requires little attention and doesn’t take up much room, but will reward you with a yield of up to 240g/plant within 12 weeks of seeds sprouting. Her THC content of 14% makes for a mellow and clear-headed high, and her terpenes infuse each hit with flavours of earth, pepper, and pine.

Royal Cheese Automatic

Royal Cheese Automatic easily makes it onto the best outdoor autoflower list. Why? Because she churns out heavy yields with lightning-fast efficiency.

This compact cultivar does well in 11L pots and peaks at a height of 120cm when left untrained. She’ll cruise through veg in 3–4 weeks, where frequent applications of liquid seaweed and fish emulsion will fuel quick leafy growth. From the moment she starts flowering, you’ll only have to wait 7–8 weeks to harvest and trim your buds. Make sure you have enough stash jars to handle an output of up to 210g/plant.

This strain stems from Cheese, Royal Critical, and a cannabis ruderalis specimen. Her THC content of 15% and potent terpene profile converge to impart a physically relaxing and stoning experience.

NYC Sour D Auto

Not only does NYC Sour D Auto rank as one of the best autoflowers for the outdoors, but she packs a THC-heavy punch. This strain germinates quickly and will grow happily in an 11L pot. Position her in the sunniest spot in your garden for optimal growth. During veg, apply light defoliation if you live in a humid environment to curb mould later down the line. Repeat the same during weeks 3–4 of flowering to boost aeration in the canopy. Lay off feeding 2–3 weeks before harvest to flush your plants for superior flavours. Get your gear together and start harvesting up to 180g/plant around 11–13 weeks after germination.

NYC Sour D Auto has its roots in Mike Tyson’s cannabis company Tyson 2.0 and became widely available at the hands of Royal Queen Seeds.

Amnesia Haze Automatic

As the autoflowering version of Amnesia Haze, this hardy cultivar serves up a sizeable yield in a fraction of the time as her predecessor.

Start your seeds using the paper towel method, or simply sow them directly into their final pot if you’re willing to keep them hydrated enough for several days. During veg, consider applying foliar sprays of compost tea and lactic acid bacteria to keep her microbiome in tip-top shape.

You’ll notice preflowers start to develop during week four—a sign to switch to high potassium and phosphorus levels. Keep her well watered if you’re growing in dry conditions, and consider putting up a small polytunnel around your plant if you’re dealing with constant rainfall towards the end of bloom. Prepare to harvest a reward of 130–180g/plant around 11–12 weeks after your seeds sprout.

This sativa-dominant hybrid possesses a THC content of 18% alongside medium CBD levels. This phytochemical mix produces a relaxing and clear-headed high suitable for any time of day. Notes of citrus, earthiness, and pepper are strong on both the inhale and exhale.

This compact strain will remain stocky throughout the 4-week vegetative phase during which you’ll watch her develop a sturdy main stem, short internodes, and strong petioles. By week five, she’ll stand at just 35cm if trained early and stretch to 77cm by the time harvest swings around. During bloom, she’ll develop dense and uniform colas drenched with resin. If grown in a sunny, warm, and fertile spot, you can expect a yield of up to 180g/plant.

With superb germination rates, Apple Fritter Automatic starts strong out of the gate. Sow her into pots or directly in the ground and keep her warm, and you’ll have a thriving 3cm-tall seedling by the end of week one.

If left untrained, consider staking your plant if you’re dealing with adverse weather conditions.

During bloom, your plant will reach a height of 60–110cm depending on your approach. Defoliate enough to ensure light and air have good access to the inner canopy. Within 11–12 weeks from germination, you’ll find yourself harvesting up to 180g/plant.

Due to inheriting genetics from Sour Apple Auto and Animal Cookies, Apple Fritter quickly gained recognition as one of the highest-yielding autoflower strains among outdoor growers.

North Thunderfuck Auto

North Thunderfuck Auto knocks it out of the park when cultivated out in the elements. Not only does she hold her own against harsh conditions, but she produces some of the most stunning buds among strains in this category.

Directly sow seeds outdoors and cover them with a bell cloche until sprouting occurs to protect them from nighttime temperatures. Your plant will charge through veg in just four weeks and start transitioning into a flower once it develops a dense and stocky canopy. During bloom, defoliate where needed to expose any shady bud sites to direct sunlight. Flush your plant around two weeks before harvest on week 11, and watch her fan leaves and buds start to display striking hues of deep purple as anthocyanin levels rise.

So, what can you expect after drying and curing? Well, with a THC content of 21%, North Thunderfuck Automatic lands a hard-hitting and long-lasting high that drives undulating bouts of physical relaxation and mental stimulation. Unique tastes of earth, lime, and skunk make her an instant favourite among many cultivators.
