These are the really interesting ones, the ones that offer a great balance between speed and performance. The automatic genetics that take the least time to produce a large crop usually have a whole culture cycle of 70 to 75 days, and among them the following stand out:
From the Lowryder came the Lowryder#2, which needed a few more days to complete its cycle, but it is of higher quality. The vast majority of autoflowering strains nowadays come from crosses with Lowryder#2, and have a total growing cycle of 65 or 70 days or more
Don’t rely too much on people telling you that you can harvest a cannabis plant in less than 50 days from germination, because it’s impossible for it to be ripe or to have reached a good size.
🧐 Faster and more productive autoflowering seeds
If you want to be able to harvest a little earlier for some reason, you also have products like GHE’s Ripen, which speeds up ripening by a few days in both auto and regular cannabis varieties.
The ideal is not to force the plants during cultivation, but if you need to have weed as soon as possible there are some tricks you can use. However, you have to understand that a large harvest cannot be achieved in a short time, so you have to sacrifice production if you want to save time in growing.
One of the fastest marijuana plants in the world! To achieve this impressive variety, the breeders have genetically fused a Lowrider #2 and a Ruderalis, resulting in a plant with a flowering time of only 6-7 weeks, with a very rich and powerful flavor, with an effect that will leave you really touched…
The fastest autoflowering plants are those that bloom with only 20 days of growth. The problem with these plants is that they do not have time to reach a good size before they start to flower, so they are quite small.
After germinating these seeds, Easy Bud will explode into a mature plant in as little as eight weeks. Prepare to harvest up to 325g/m² from indoor plants, and between 30–80g/plant from outdoor specimens.
Autoflowering seeds can be both sativa and indica. However, they have been crossed with a type of cannabis called ruderalis. This enables them to flower on their own in as little as 2-4 weeks without exposing them to strict 12 hour light regimes.
As the progeny of White Indica and ruderalis, Easy Bud produces frosty flowers featuring a THC content of 12% alongside citrusy and earthy terpenes. These buds won’t blast you to the moon, but they will offer a soothing and subtle effect perfect for any time of day.
As well as offering a rapid flowering time, Candy Kush Express is a rich source of terpenes, emanating notes of sugary sweet citrus. Her speed of growth and incredible taste make her a great strain for cannabis chefs who want a crop that yields well on a regular basis. This strain features a close balance of 60% indica genetics and 40% sativa, which exerts an effect that relieves tension from the body while keeping the mind alert and functional.
Feminized cannabis seeds are designed to produce only female plants. Feminized seeds will produce a female plant 99.99% of the time. Don’t waste your time trying to produce flower from a male plant – they will only pollinate you females, resulting in seeds rather than bud.
Quick One is one of the fastest auto-growing strains on the planet. The plant is based on the original auto flowering strain – Lowryder. This strain was created from a cross between William’s Wonder x Northern Lights x Ruderalis. These plants are usually ready for harvest in 8 weeks from germination. The plants also reach between 50 and 60 cm and can yield up to 150g per plant.
Our team has created both fast-flowering feminized genetics and autoflowering genetics to satisfy all types of growers. The former offers all the benefits of photoperiod strains, but with a reduced flowering time.
When it comes to smoking, she provides an overall mild but long-lasting high that is deeply relaxing and speckled with euphoria. A THC content of 15% hits just the right spot for smokers looking to somewhat maintain their ability to function.
This is one strain that is a real “blink, and you’ll miss it” experience. Taking just about 8 weeks to mature, Caramel Automatic derives from Sweet Caramel x ruderalis, but is a true indica-dominant character in her own right. After her short growing cycle, you can expect to see returns of around 400–450g/m². A simply huge yield for a plant that stands not much taller than 100cm.
Ready to harvest in 8 weeks, there’s little wonder why Quick One is included on our list. Reliable and robust, this strain was formed by crossing Lowryder 1 with Old School Indica. Sure, she’s short in stature, but that only means you can fit more plants into your growing area! Reaching heights of 50–60cm indoors and 60–100cm outdoors, she’s unlikely to overstay her welcome. Indoor plants will return a respectable 275–325g/m², while outdoor plants are capable of churning out a satisfying 100–150g/plant.
9. Original Auto Skunk (FastBuds)
Complete with a sweet, fruity taste and a pungent aroma, the experience of smoking La Diva will make you feel like a star, indeed. This is only enhanced by a THC level of 15–20%, which all but banishes worry from your brain.
Even though some of the previous strains will reach harvest in a flash, the question of whether it’s possible to speed them up more is still top of mind for many.
This indica-dominant strain is ready to harvest in next to no time, or 6–7 weeks, to be precise! She’s derived from two big-hitter strains: Tropicanna Cookies x Lemon OG. Watermelon Automatic brings all of the finer aspects of her parentage into one neat package. She grows to 80–110cm indoors and 100–120cm out, but, with a little LST, you can keep her more grounded if you so prefer. Once ready to harvest, you can expect to see some pretty sizeable yields of up to 500g/m² indoors and around 100g/plant outdoors.
However, the most obvious benefit of autoflowers is their speed. With that in mind, we’ve assembled a list of the top 10 fastest autoflowering cannabis strains. The majority of these lightning-fast strains race from seed to harvest in 8 weeks or less, but one thing’s for sure; they all deliver top-quality cannabis.
