10 Fast-Growing Cannabis Plants for Impatient Gardeners

There are a significant number of prospective cannabis growers who are turned off by the fact that cultivating pot is classified as a lengthy and arduous process.

How often have you read online guides that emphasized the expense involved in growing marijuana?

Aside from the nutrients, fans, space, seeds, and soil or growing medium, you have to consider the lengthy flowering period.

Once you include the seedling and vegetative stage, you will find yourself waiting months for your marijuana to harvest. The internet age has spawned an era of impatience; a desire to get things done yesterday. As a result, breeders have busily looked for ways to speed up the weed growing process.

In the old days, those who purchased their seeds from the black market would attempt to create hybrid strains to find attributes suited to clandestine growth, and designed for a fast turnover. As discretion was paramount, indoor growing was essential which meant the ensuing plants would be short and stocky but provide above-average yields. Occasionally, they would use auto-flowering strains. In the end, they were able to benefit from a fast flowering period and a lightning-quick turnover.

Today, this knowledge has been gathered and updated. As a result, novice growers can utilize a huge array of cannabis strains with short flowering times. It is even possible to shorten the vegetative period in certain strains, which means professional growers can churn out multiple harvests each year.

In this guide, we have located ten marijuana strains that grow exceedingly quickly; the best short flowering strains as well as the quickest autoflowering seeds. Imagine finding a strain capable of flowering in just seven weeks! We have included auto-flowering and photoperiod options to increase the likelihood of you finding the perfect marijuana strain for your needs. Before you start, lease make sure that it is legal to grow cannabis in your state of residence and that you remain within the legal limits.

Best Short Flowering Strains: Photoperiod Strains That Grow Quickly (7-9 Weeks)

These strains have a shorter flowering period, which helps make sure they’re ready for harvest relatively quickly. These strains are ideal for impatient gardeners that really just want their flower to be available as soon as possible.

1 – Lowryder (Hybrid Cannabis Strain)

Although it is classified as a hybrid, Lowryder is very close to being a balanced 50/50 strain. It was inbred for an incredible nine generations by Joint Doctor Seeds, which is why it has its famous diminutive size.

Often compared to Bonsai trees, Lowryder is a tiny but mighty marijuana strain that seldom grows higher than 16-inches; a fact that makes it perfect for indoor grows with limited space.

It is a tough plant capable of surviving in harsh climates, which is why it is grown in places such as Finland, Alaska, and Canada. It is regarded as an all-time classic hybrid and is a cross of Willy’s Wonder and Northern Lights #2. With a THC content ranging from 12% to 20%, Lowryder is a strain suitable for most novices, so long as they use it responsibly.

It is one of the easiest strains on the market to grow because it requires very little maintenance above the bare minimum. With a flowering time of just 40-45 days, Lowryder can provide you with its energetic high in double quick time, and it clocks in just below many of the popular choice 50 day flowering strains! It produces around 12 ounces per square meter planted when grown indoors.

Lowryder is a fragrant strain with an aroma reminiscent of Christmas. A combination of a sweet and piney scent is a real treat to the senses. Once you have a few smokes, you will definitely enjoy the fruity flavor, although you should be wary of the strong aftertaste.

It is popular among creative individuals such as musicians and writers because it helps inspire creativity. It offers relaxation without causing the body to ever feel heavy. The cerebral buzz eventually makes its way to your body, and don’t be surprised if you end up in a fit of giggles!

You can use Lowryder as a daytime strain because your mind remains clear. It is also known as an excellent strain for socializing, so feel free to take some before hanging out with friends. However, as it is a hybrid, it has been known to make some users feel sleepy. We recommend experimenting at home to see how it affects you. Lowryder has been used to treat insomnia and chronic stress disorders.

2 – Critical Kush (Indica Cannabis Strain)

Critical Kush is an extremely powerful and potent marijuana strain that is NOT for new users! It is an indica dominant (90%) hybrid created by Barney’s Farm Seeds. Although Critical Kush is technically a hybrid created from a cross of OG Kush and Critical Mass, its effects are predominantly indica.

Growing Critical Kush is fairly easy, which is unusual for such a potent plant capable of producing high yields.

Although it is tough enough to withstand adverse climate conditions, it grows best in warm and temperate conditions. It can complete its flowering cycle in just 50-60 days, and some growers have reported a staggering indoor yield of 21 ounces per square meter.

If you decide to grow Critical Kush, be VERY careful when using it! It has an exceptionally high THC content of up to 25% and is capable of hitting you like an express train. It is 100% a marijuana strain for late evening or night time use because it induces couch-lock fairly quickly.

In higher doses, Critical Kush will make you feel sleepy, so we say it’s best left for when your day is finished. Users often report a feeling of euphoria, and while it changes your mood for the better, you won’t be able to do much other than sit or lie down and enjoy the experience.

It is an aromatic strain known for its earthy scent that carries the merest hint of sourness. It offers a creamy, herb-like taste with a slight touch of citrus. Critical Kush has become one of the most popular medical marijuana strains and is used to treat and manage a host of conditions. It is championed by many as an excellent stress-reduction tool, and also has pain relieving qualities. That’s why MMJ cardholders use it to treat migraines, muscle spasms, back pains, and a variety of other inflammatory conditions.

3 – Early Girl (Indica Cannabis Strain)

Occasionally referred to as ‘the girl next door’ within the marijuana community, this indica dominant (75%) hybrid is known for its rapid flowering time of 7-8 weeks. Early Girl was created by Sensi Seeds in the 1980s when the famous breeder crossed Afghani and other northern Indian Indica strains with a potent Mexican Sativa.

If you are a new marijuana grower looking for an effective stress-buster, the Early Girl strain is your girl!

As well as being easy to grow, Early Girl is highly resistant to the majority of pests and molds. It is also a durable plant which is more forgiving than most when it comes to making amateur mistakes. Early Girl grows equally well in soil or in a hydroponics setup, and the Sea of Green technique is an excellent method of improving yield. You can expect 14-18 ounces of bud per square meter.

Although Early Girl’s THC content goes as high as 20%, you can find versions with just 12% THC. Either way, this strain is very different from Critical Kush because it provides you with a gentle, yet noticeable, high. At the start, you will feel clear-minded, and before you know it, your mood has improved and you become more amiable and chattier.

Although Early Girl is relatively potent, you never feel overwhelmed. While you won’t experience a sudden burst of energy, you will enjoy the feeling of euphoria that makes you more sociable. Eventually, the indica part really kicks in to soothe and relax the body. It is not a strain for a secret outdoor smoke due to its pungent lemon scent, but its tangy citrus and pine flavor is a real treat.

In the medical world, Early Girl is preferred by patients in search of a mood booster. As a result, individuals with depression may find this strain to their tastes. While it is not regarded as a potent strain, chronic pain sufferers suggest that its long-lasting and even effects are just what the doctor ordered.

4 – OG Kush (Hybrid Cannabis Strain)

This marijuana strain is one of the most famous West Coast varieties, and its origins are as mysterious as this weed is delicious! According to one story, the ‘OG’ relates to OverGrown.com, which was the largest cannabis site in the world until the Canadian government spoiled the fun and shut it down in 2006. Another tale suggests it is an homage to Original Gangster, a famous California strain.

OG Kush is said to be a cross of Hindu Kush and Chemdawg, but since it came from bag seed in the 1990s, it is difficult to say this is a fact. Imperial Genetics has been credited with bringing the seeds to Colorado and Southern California from Florida, and there are several well-known phenotypes of the strain, including Alpha OG and Tahoe OG.

OG Kush is an indica-dominant (75%) hybrid that has a high THC content of up to 26%, and its indica properties come to the fore as soon as you use it.

OG Kush is notoriously strong and can easily prove too much to handle for inexperienced users. It hits you hard almost immediately with a potent euphoric high coupled with a powerful cerebral buzz and a shot of energy.

However, once the initial effects wear off, OG Kush gets to work on your body, and soon you will feel chilled out, relaxed, and happy. It is an ideal strain to use at the end of a hard day at work, but be careful; some users have reported feeling spaced out after using it. This strain is also associated with the munchies.

OG Kush is famous for its strong, earthy scent with sticky, resinous buds as a feature of the strain. It tastes a lot like it smells; fresh and earthy, with a subtle woody texture along with a semblance of spice. As a medical marijuana option, OG Kush is often used to provide muscular relaxation, and long-lasting relief from nausea, migraines and chronic pain. It is also a popular option among those with anxiety or depression. OG Kush has a flowering time of around eight weeks and typically yields up to 17 ounces per square meter.

5 – Superglue (Hybrid Cannabis Strain)

If you’ve ever worked in an office, there will be days where you will do just about anything to break the monotony. While Superglue is not the right option when at work due to its sedative effects, it is perfect for when you get home and want to relax after a day you would rather forget.

This hybrid strain is slightly indica biased (60%) and was created by Seedism Seeds. It is a cross of Northern Lights and Afghani. With a THC content ranging from 18 to 23%, it is a marijuana strain that warrants respect. After a few tokes, you’ll feel uplifted by a potent cerebral high.

See also  Do Weed Seeds Smell

Although it enables you to stay functioning at work, we believe Superglue is a better strain to use at home because the indica side takes over and begins relaxing the body. Superglue’s sedative effects really creep up on you, and soon you’ll succumb to couch-lock – not a good look when you have to file an office report!

The strain gets the name ‘Superglue’ because users are typically glued to their sofa or bed soon after using it!

It is a relatively difficult strain to grow because of its susceptibility to mold. Superglue also develops large colas, so make sure there is good airflow in the grow room. It will thrive if you grow it indoors or outdoors, but if you stay inside it will flower in as little as eight weeks. You should benefit from a yield of 14 to 18 ounces per square meter planted.

Superglue’s strong diesel scent may be off-putting to some, and its woody, chemical, and citrus flavor pattern is an acquired taste. While you may think it doesn’t sound appetizing, we can assure you that it tastes fantastic. Superglue is used by people with depression and has also been a helpful aid for insomniacs. Once the effects begin to wear off, you’re likely to feel extremely hungry.

Quickest Autoflowering Seeds: Fast-Growing Cannabis Flowers (7-12 Weeks)

In addition to cannabis strains with short flowering periods, there is a second classification of speedy weedy options, which are referred to as auto-flowering strains.

6 – Red Dwarf (Indica Cannabis Strain)

Red Dwarf is a special Skunk variety strain that is an extremely rare auto-flowering plant. It possesses cannabis ruderalis genetics, which is the third type of marijuana plant (aside from indica and sativa). Ruderalis is said to have grown in the Soviet Union and Russia in general and is known for its ability to thrive in harsh climates.

Red Dwarf was created by Buddha Seeds, and it is renowned for its remarkably fast flowering time of just six weeks!

Although it has ruderalis genetics, Red Dwarf is a pure indica and a cross of ruderalis and a White Dwarf phenotype. Aside from the rapid flowering time, this strain is adored by indoor growers because it grows small and squat, which makes it easy to grow in a smaller space. Seriously, you can place a few pots in a broom closet and it will provide more than enough room! Moreover, it is possible to grow up to 16 ounces of bud per square meter planted.

Once you grow Red Dwarf, please note that it has an extremely pungent odor which makes it tough to conceal. You will feel almost instant sedation when you use this strain with moderate couch-lock that keeps you awake but utterly relaxed. It is definitely a bad choice of smoke at work because you will be easily distracted and spaced out. It won’t take a detective to figure out that you are completely stoned!

In medical terms, Red Dwarf is favored by patients with conditions such as tension headaches, migraines, chronic pain, appetite loss, inflammation, stress, and nausea. The bud has a scent and taste that reminds you of coffee, and the nugs are rather hairy and coated with beautiful white trichomes. It has a THC content of between 7% and 15%, making it mild enough for new users.

7 – Hobbit (Hybrid Cannabis Strain)

This is an extremely alluring strain developed by Kannabia Seeds. Noted for producing a high yield despite a short flowering time of 65 days, this auto-flowering marvel is becoming very popular. It is a balanced hybrid and a cross of Ginger Ale and an unknown Ruderalis strain. As a consequence, Hobbit is a fairly balanced mix of sativa, indica, and ruderalis, a rarity in the world of weed.

As you can probably guess, Hobbit was named after the famed characters from the Lord of the Rings novels. While its THC content can be described as ‘above average’ at 15%, it is not a strain that will knock you flat out. Indeed, the high is every bit as balanced as one might hope, which means it can be used in the morning, evening, or at night. For most users, it is the strain of choice when they wish to relax with friends and have a day of pure laziness.

Soon after using Hobbit, you should experience a feeling of relaxation and happiness. Don’t be surprised if you develop a sudden appetite. Eventually, you feel a slight tingle in the forehead and behind the eyes. Next, the high makes its way to the rest of your body and ensures you feel a little bit sleepy. However, we have to emphasize this fact; you should be in a state of complete bliss throughout.

Hobbit is used to treat a wide range of conditions including insomnia, depression, hypertension, and mood swings. It is especially useful if you have chronic pain and find it difficult to sleep. The sweet aroma is pleasant, and the sugary strawberry taste makes you want to come back for more. When you grow Hobbit indoors, you can get up to an ounce per seed. However, when you grow outdoors, the yield swells to over two ounces per seed. As it is highly resistant to fungus and pests, Hobbit is ideal for newcomers prone to making mistakes.

8 – White Ryder (Hybrid Cannabis Strain)

Riot Seeds developed White Ryder, which is a cross of Lowryder and White Dwarf. It is a fascinating attempt at creating a Ruderalis version of the famed White Widow strain.

Thanks to the efforts of this particular breeder, you now have access to a strong indica dominant hybrid that auto-flowers in less than 80 days.

The Ruderalis genetics means it grows relatively short and squat, perfect for indoor growers! Also, when we say it is strong, we mean it. With a THC content of up to 24%, White Ryder is probably a strain best avoided by inexperienced users. If you decide to use it in any case, make sure you begin with a small dose. It doesn’t take long to get to work as you should feel an almost immediate uplifting cerebral high that initially clears the mind and helps you focus on certain tasks.

However, we don’t recommend White Ryder for morning or afternoon use. The initial mental stimulation you feel is soon replaced by a feeling of full body relaxation. Before you know it, all you want to do is find the nearest place to sit down as couch-lock takes full effect. Eventually, you will struggle to move so if you take this before or during work, you will regret it. It is best used in the evening to help you wind down and chill out.

White Dwarf is said to be effective as medical marijuana. Its sedative effects make it a great option if you suffer from insomnia. Have a few tokes about an hour before bed, listen to some good music, and drift peacefully off to sleep. White Dwarf is also great if you need to alleviate the yolk of body pain. Finally, it is a strain that may have some merit if you suffer from depression or an anxiety disorder.

9 – Purple Cheese (Hybrid Cannabis Strain)

This strain sounds like cheese that has been left out too long but trust us; it is one of the finest fast-growing auto-flowering marijuana strains you’ll find. It was bred by Auto Seeds and is a cross of Blue Cheese, Lowryder, and Purple No. 1. The breeder wanted a hybrid that didn’t come with the often-intense flavor of Blue Cheese, and they also wanted a relatively high CBD strain, and they have achieved their goal with Purple Cheese.

Purple Cheese is a balanced hybrid with 12-16% THC, but its 4% CBD content ensures you benefit from a balanced high.

When Purple Cheese was initially released, it was considered one of the most potent strains around. If nothing else, this is an indication of how quickly breeders have developed new techniques for growing ultra-powerful strains.

If you’re used to rapid effects, you’ll need patience when using Purple Cheese as the high takes a while to appear. Eventually, you will feel positively euphoric with a clear mind and a lot of energy. When the effects make their way to the body, you’ll have a decided feeling of couch-lock. Overall, the high can last for up to three hours.

Purple Cheese is yet another strain on this list known for how easy it is to grow. It doesn’t take up much vertical space which makes it perfect for an indoor grow.

Although it isn’t quite as short as Lowryder, this plant seldom grows higher than 80cm indoors. It should flower within 8-9 weeks and produce up to 14 ounces of bud per square meter planted. Purple Cheese is a unique strain insofar as it allows for two outdoor harvests per year, in July and October.

Users love Purple Cheese because of its delightful fruity aroma. It is less cheesy tasting than Blue Cheese, but you should still enjoy the flavor. Due to its full-body effects and high CBD content, this strain is one of the most popular choices for patients with body pain. It is especially useful if you are suffering from a degenerative condition. Purple Cheese is also used by individuals with depression and it may provide you with some benefit if you suffer from an anxiety disorder.

10 – Royal Haze (Sativa Cannabis Strain)

Also known as Royale Haze, this heavily sativa-dominant (85%) hybrid is filled with exotic flavors that dance on your tongue. It was originally created by Dinafem Seeds and is a cross of Northern Lights, Skunk #1, and Haze genetics. Royal Queen Seeds has developed an auto-flowering version by crossing Skunk, a Ruderalis strain, and Amnesia Haze.

Not only does Royal Haze have a powerful THC content of up to 20%, but it is also known for providing one of the longest lasting highs. You should feel intense euphoria within moments, but this cerebral buzz is not fleeting. Instead, it can last for hours so its effects may come as a surprise to new users.

Royal Haze is the ideal strain for anyone seeking a mood boost. As well as clearing the mind, it helps drive creativity. The soothing sensation you’re likely to feel towards the back of your head will relax you in ways you can’t even imagine. The body high provided by this marijuana strain is not particularly strong which means you should be able to complete your tasks without a problem.

Royal Haze isn’t a difficult plant to grow, and it is different from most sativas insofar as it has strong stalks.

Its Skunk #1 genetics ensure that it is sturdy and full of branches. It can grow up to 14-feet tall outdoors which makes it a bad choice for a secret marijuana field! It adapts well to Screen of Green and Sea of Green training techniques, but you should perform early topping to manage its height. It flowers in approximately 10 weeks indoors and produces up to 18 ounces of bud per square meter.

The spicy citrus and pine fragrances are pleasant, as are the delicious tropical flavors with citrus lingering on the palate. As you might expect, Royal Haze is valued as a stress reliever and an anti-depressant. It is also used by individuals with PTSD and anxiety. The high THC content means it could also act as an effective painkiller.

Final Quick Tips on Getting to Harvest Faster for Impatient Gardeners

First and foremost, choose one of the ten fast-flowering strains we mentioned above. No matter what tricks you use, certain strains will NOT flower quickly. For example, Hazes are notorious for their lengthy flowering periods. In fact, Haze #1 can take 12-16 weeks! Once you have selected your ideal strain, consider the following for a faster harvest.

1 – Greater light exposure during the vegetative stage

Your marijuana plants will remain in the vegetative stage as long as they receive 14+ hours of light a day. Traditionally, plants grown using an 18/6 cycle (18 hours of light, 6 hours of dark) are more resistant to pests and diseases. However, if you expose your plants to 24 hours of light a day, they will grow faster. As a result, you can force them into the flowering stage sooner.

2 – Begin the flowering stage ASAP

Did you know that non-auto flowering marijuana plants can be flowered directly from their seeds? All you need to do is change the light schedule to ensure your crop is exposed to 12 hours of continuous darkness each day. This process makes your plants believe that winter is coming which means they begin making buds as soon as they are capable.

In most cases, the countdown begins around a month from the planting of the seed, but with certain strains, you can trim a week or two off the timeframe. However, please note that flowering from seed is inefficient because your plants won’t have enough time to grow stems where the buds form.

3 – React to problems quickly

A lot of new growers don’t seem to realize that growth slows down every time your plants gets sick. Every new issue adds days, or even weeks to total growth time if you don’t solve it at warp speed. Key problems to look for include pest infestation, nutrient burn or deficiency, light burn, and heat stress.

Final Thoughts on Fast-Growing Cannabis Flowers

The next time you’re trying to decide which cannabis strain to grow, take into consideration these 10 fast-growing cannabis flowers for even the most impatient of gardeners. Choose from either the best short flowering strains or the quickest autoflowering seeds; either selection will give you the results you’re in need of. As always, be sure to give your plants plenty of tender love and care, so that they can grow up to be strong, healthy, bountiful, and super high-inducing.

10 Fast-Growing Cannabis Flowers for Impatient Gardeners

Growing cannabis can be an arduous process. Beyond the space, materials, and nutrients needed, time and light are the most essential ingredients in the cannabis cultivation equation. But what if you’re impatient or short on time? Is there a way to speed up the growing process?

Historically, black market growers would seek out or hybridize strains to harness attributes that catered to their surreptitious needs. These plants would usually be short and stalky with larger-than-average yields, and in some instances they would be autoflowering (such as a ruderalis hybrid). They were designed to be fast-flowering for both a quick turnover and so they could be easily relocated from time to time.

The fast-flowering cannabis strains listed below are now emerging for professional and hobby growers to utilize. They’re perfect for novice growers as well as set-it-and-forget-it growers who want to squeeze out a harvest with little time to spare. The list includes a mixture of both photoperiod and autoflowering varieties so you can find the perfect plants for your setup.

Photoperiod Strains That Grow Quickly (7-9 Weeks)

Lowryder

Lowryder is a hybrid strain that was inbred for nine generations by Joint Doctor Seeds to give it a dwarfed size. Growing no more than 16 inches tall, it’s the cannabis equivalent of a bonsai for the discrete grower’s windowsill or balcony. Lowryder’s small size comes from a species of cannabis ruderalis crossed with Northern Lights #2 and then William’s Wonder. Consumers, be patient with this strain: its medicinal and cerebrally stimulating effects have a slow but powerful onset. A mild earthy aroma radiates from the small, conic buds which autoflower in a short 40 to 45 days. Lowryder is a stalwart plant that can survive in harsh, colder climates, making it a popular strain in northern regions like Finland and Canada.

Critical Kush

Critical Kush from Barney’s Farm is a mostly indica strain that blends together two famed cannabis staples, Critical Mass and OG Kush. Aromatic notes of earthiness and spice usher in a calming sensation that relaxes the mind and body. Critical Kush pairs a staggeringly high THC content with a moderate dose of CBD, making this strain a perfect nighttime medication for pain, stress, insomnia, and muscle spasms. Growers cultivating this strain indoors will wait 50 to 60 days for Critical Kush to complete its flowering cycle.

Early Girl

Early Girl is the wallflower of cannabis strains since its introduction in the 1980s. Lovingly preserved by the breeders at Sensi Seeds, this strain is lazy and relaxed, nothing over the top. A 75/25 indica-dominant hybrid, Early Girl is a good one for those new to cannabis who would like relief from stress. Also a great strain for novice growers, it’s compact, resilient, and has a particularly short flowering time of 7 to 8 weeks. Early Girl grows especially well outdoors, but won’t put up a fuss if she’s stuck inside.

OG Kush

OG Kush makes up the genetic backbone of West Coast cannabis varieties, but in spite of its ubiquity, its genetic origins remain a mystery. Popular myth maintains that Chemdawg and Hindu Kush parented OG Kush, passing on the distinct “kush” bud structure we see in many strains today. However, we can’t be sure because OG Kush first came from bag seed in the early 90s. The earliest propagators (now known as Imperial Genetics) are said to have brought the seeds out of Florida to Colorado and southern California, where it now flourishes. There are many different phenotypes of OG Kush, some of which include Tahoe OG, SFV OG, and Alpha OG.

OG Kush is cherished for its ability to crush stress under the weight of its heavy euphoria. It carries an earthy pine and sour lemon scent with woody undertones, an aroma that has become the signature of OG Kush varieties and descendants. With OG Kush, patients most commonly cite improvements in migraines, ADD/ADHD, and stress disorders.

Superglue

Superglue is a hybrid strain bred by Seedism Seeds. A cross between Afghani and Northern Lights, Superglue inherits indica growth patterns along with a sweet caramel and pine aroma. Superglue brings calming relaxation to the mind and body, but leaves you functional and energetic enough for social activities or a productive afternoon.

Autoflowering Strains That Grow Quickly (7-12 Weeks)

Red Dwarf

Red Dwarf is a rarer strain of cannabis that is an autoflowering plant. This trait comes from its cannabis ruderalis genetics, which is a third variety of the plant that’s usually not bred due to its lower THC content. The wonders of selective breeding from Buddha Seeds have resulted in seeds that grow to adulthood in an incredibly short six weeks. This strain’s squat, small plants are easy to grow in smaller spaces, making it a popular choice for growers who want something simple and fast. Indica-dominant, Red Dwarf will eventually make you sleepy, but not without some relaxed euphoria first.

Hobbit

Hobbit by Kannabia Seeds is a resilient autoflowering variety with sweetness and strong elemental resistance. This strain has a sweet aroma that has been described as “strawberry candy” and an equally sweet smoke with latent earthy notes. Hobbit deftly combines stimulating Haze elements with a pervasive body buzz that is lightly weighted while remaining pleasant and functional. Many growers covet this autoflowering wonder for its quick 65-day flowering time and above-average yield.

White Ryder

White Ryder is Riot Seeds’ attempt to create a ruderalis version of White Widow by crossing Buddha Seeds’ White Dwarf against Lowryder. By blending two stout, autoflowering plants, Riot Seeds created a potent indica-dominant hybrid that finishes in under 80 days and can easily be hidden from view. Enjoy this flower for anti-anxiety and sleep-inducing effects.

Purple Cheese

Purple Cheese is an indica-dominant autoflowering hybrid that combines Purple #1, Blue Cheese, and Lowryder. Bred by Auto Seeds, Purple Cheese was designed to have a sweeter, less cheesy flavor than its Blue Cheese parent. It does, however, inherit a tight bud structure and a high CBD profile. With a palatable fruit aroma, Purple Cheese delivers powerful full-body effects best suited for night owls or patients treating pain. Colder climates will bring out this hybrid’s purple hues, and for best results, growers should keep this autoflowering variety between 50-80 cm in height.

Royal Haze

Royal Haze (or Royale Haze) by Dinafem Seeds is a mostly sativa strain bred from Skunk, Haze, and Northern Lights genetics. Taking after her Haze parent, this sativa inherits a spicy citrus flavor and buzzing, energetic effects that keep you alert and productive throughout the day. Outdoor growers will appreciate her flexibility and resilience even when the temperature drops, although her 10-11 week flowering cycle demands a bit of patience.

An autoflowering rendition of Royal Haze was bred by Royal Queen Seeds, who mixed Amnesia Haze, Skunk, and a ruderalis strain. Its effects are similarly energizing and cerebral.

Consider Bubba’s gift from Humboldt seeds. 6 weeks flowering and nice purple hues

Im growing Bubbas Gift this season and it hasnt started to show sex yet. Just hope its done before the 1st week of October. Weather in the North East US can get really crappy in Oct . Anybody else out there have experience with this strain?

Speedy Chile fast by royal Queen is the fastest I’ve heard of. It’s finished in 56 days from germination and only needs 14 days veg. 16% Thc. Fem photo 80-100cm tall and 500+ grams per m2 indoor. Critical poison fast should be on the list too. Finished in 40-45 days 18% thc Fem photo 500+ grams per m2 indoor.

HI bro, how many plants per m2 can u grow with these??

Wow. This is a real treat for both the consumers and the farmers. Personally, I like Green-O-Matic Auto. It sorts of suits me. Thanks a lot for sharing.

Pineapple Express #2 from G13 Labs all day on my 3rd run with this strain and I have more chasing it

Bro, i have a special pheno of her, been runnin her for like 4 years now.. Its amazing what she does in just 50 days… I like to run an extra 10 days though…

got some free seeds from just cannabis seeds and so I thought I would throw a few of them in the dirt, only one was fem and a hearty little sativa that I topped 3 times for max yield and about 45 days in it looked like I was well on my way to getting 1/2 lb off of her when the buds fattened up in coming weeks considering I had about 4 more weeks before harvest, but just for fun I thought I would check the trichomes at a time I felt was early, and WTF. I’m sitting on 15 to 40% amber and no clear trichomes, in 45 days, on a pure sativa!! Well my yield wont be as big but its an early surprise. Wish I would have cloned her,

Just leave a couple small buds and regenerate growth after your harvest.

Lemon Pie Auto takes 3 months/12 weeks seed to buds

Gorilla Girl F1 Fast is my favorite. Not sure if anyone likes it too.

Fast Bud #2 Auto seems one of the exciting options. But I haven’t tried it. Can anyone share how exactly would it be?
