5 Autoflowering Cannabis Strains To Grow in 2021

Let's start with our picks for the best autoflowers. Each offers something special—whether it's unique cannabinoids, lightning-fast growth, or exceptional yields.

Sunset Sherbet Automatic by Zamnesia Seeds

Genetics	indica-dominant hybrid
Parents	Girl Scout Cookies x Pink Panties x ruderalis
THC	18–24%
CBD	low
Flowering time	8-9 weeks from seed to harvest
Price per seed	starting at €3,60

This thing is drenched in trichomes. Glistening like a snowflake, it’s wonderful to behold. But the flavours are the main reason people go for Sunset Sherbert Automatic. Powerful, sweet notes of berries and orange zest invigorate the palate and make for a very moreish smoke. Underpinning it all are deeper, skunky notes which indicate that, while this strain may taste light and airy, it’s a serious player when it comes to potency.

Royal CBDV Automatic by Royal Queen Seeds

Genetics	75% sativa, 20% indica, 5% ruderalis
Parents	Solomatic CBD x Durban Poison
THC	0.3%
CBD	5%
CBDV	5%
Flowering time	8-9 weeks from seed to harvest
Price per seed	starting at €9,50

Royal CBDV Automatic is a strain full of cannabidivarin, with equal levels of CBD to boot. These two cannabinoids combined means this strain is great for relaxation, without the psychotropic components of THC-rich weed. Still, containing a little THC (0.3%), you can expect the full-spectrum of cannabinoids—nothing is left out. Flowering in as little as 6–7 weeks (with a total growing cycle of 8–9 weeks) and boasting indoor yields of up to 450g/m², this is a quick plant that will leave you well-satisfied!

This is absolutely a savoury strain. Earth and pine are the dominant flavours, and together with the relaxing effects, they will take you to places of peace and tranquillity. Enjoy this strain whenever you’re seeking a clear-headed hit.

Auto CBD-Victory by Dutch Passion

Genetics	sativa-dominant hybrid
Parents	undisclosed
THC	0.3%
CBD	4–6%
CBDV	4–6%
Flowering time	10 weeks from seed to harvest
Price per seed	starting at €19,99

Auto CBD-Victory was the first cannabis strain to offer a 1:1 ratio of CBD:CBDV. Combined with very low levels of THC, this deeply relaxing strain is perfect for all those who need to chill out, without the potent effects associated with THC. Bred from Dutch Passion’s mysterious “research genetics”, this strain was a major milestone in cannabis development.

To go with its elusive heritage, it has an interesting terpene profile. Woody flavours of pine mix with almost vinegar-like flavours. The rich, sharp notes invigorate the palate and complement the gentle effects of this strain very well.

Bruce Banner Auto by Sweet Seeds

Genetics	indica 41.1%, sativa 58.7%, ruderalis 0.2%
Parents	Bruce Banner x Gorilla Girl XL Auto®
THC	18–25%
CBD	0.1%
Flowering time	10-11 weeks from seed to harvest
Price per seed	starting at €8,33

An autoflowering take on a firm favourite, Bruce Banner Auto brings all your favourite bits of the photoperiod strain into a more hands-off plant. Retaining the super-strength that made Bruce Banner famous, this floral hybrid will make you happy and euphoric. Lasting for hours and stimulating creativity and imagination, this is not a high to miss!

This strain can be tiny, reaching as little as 50cm in height! Outdoors, however, it can ascend up to 150cm. Good yields of up to 500g/m² indoors and 150g/plant outdoors are a respectable reward for little work during the growing season. Bruce Banner Auto carries the flavours of its parent strain over, too. Floral notes, not unlike the original Diesel strains, dominate—underpinned by a certain earthiness.

CBG Auto by Kannabia

Genetics	sativa-dominant hybrid
Parents	undisclosed
THC	<0.1%
CBD	<0.1%
CBG	7–8%
Flowering time	8-9 weeks from seed to harvest
Price per seed	starting at €20,00

The long-awaited CBG Auto has arrived. With the appearance of a powerful cannabis plant, you’d be forgiven for expecting this thing to be loaded with THC. However, what it lacks in THC, it makes up for in CBG. This cannabinoid has recently become the centre of speculation, alongside CBD. Thought to have similar effects, it’s well worth giving it a go and seeing if it doesn’t provide exactly what you need.

Tasting floral and sweet, these delicious flavours are a joy to the smoke. Taken in consideration with the overall gentle effects of CBG Auto, these tastes and aromas finish it off perfectly.

Wedding Cake by Zamnesia Seeds

Genetics	indica-dominant
Parents	Triangle Kush x Animal Mints
THC	25%
CBD	low
Flowering time	9 weeks
Price per seed	starting at €5,10

Famous for its delicious flavours, Wedding Cake is still one of the best-tasting strains about. Featuring sweet notes with hints of spice and blueberries, can it get any better? Well, yes, it can. Euphoric, energising highs that fade out into blissful relaxation accompany these rich scents and aromas. The only danger with Wedding Cake is that you won’t want to smoke any other strain.

The name of this strain comes not only from its flavours. Looking at it, this thing appears like a cake covered in icing. The buds have a hefty frosting of trichomes, making them look almost white. It is clear from one look at Wedding Cake exactly how strong it is going to be. A top choice for many serious growers and smokers, Wedding Cake has to be smoked to be believed.

Sensi Amnesia by Sensi Seeds

Genetics	65% sativa, 35% indica
Parents	Hawaiian Indica x Jamaican Pearl x Afghani #1
THC	undisclosed
CBD	undisclosed
Flowering time	10 weeks
Price per seed	starting at €8,33

This sativa-dominant strain does not shy away from its genetic heritage. A potent, uplifting high defined by feelings of energy and creativity is yours for the taking. With the vigorous growth of sativa strains, Sensi Amnesia can easily climb above two metres when growing outdoors. In both indoor and outdoor conditions, very large yields are to be expected.

The flavour is light, tropical, and spicy. Betraying the strength of this strain are the citrus overtones, which are the unmistakable mark of a strong sativa-leaning strain. Though, the indica comes out a little here too. Expect subtle, dark undertones of earth.

This is not a strain to indulge in when you have things to do. Not only is it too strong for that, but it’s so magnificent that it deserves your full attention.

Royal Runtz has an average growing time and delivers good yields. Despite its futuristic strength, it has a satisfyingly classic look.

Indoors, up to 600g/m² is achievable, and reports indicate that yields of up to 1000g/plant are possible outdoors. An undeniably hefty haul.
