Best Fast Flowering Marijuana Strains in 2023 – Reviewing Marijuana Strains That Flower in 8 Weeks or Less

When it comes to growing the cannabis plant, or practically any other plant, flowering is one phase that people anxiously wait for. Some plants take longer to flower compared to others. However, when flowering does happen, it is quite a relief, and growers can see months of their hard work finally paying off. Flowering is important for marijuana plants because, at the end of the harvest, it is the flower that you are going to smoke to get high. In this article, we take a closer look at some of the best fast-flowering marijuana strains out there. 

There are two ways in which you can legally get hold of weed – you can either buy the buds from a dispensary, or you can grow your own cannabis plants and then smoke your own buds. While the former is an easier process, it is not practical to do so everywhere as dispensaries aren’t present all over the world, and the price at which you get marijuana in a dispensary is typically much higher than that of growing your own cannabis plants.

When you grow your own weed, the flowers are the labor of your love. It is weeks of your effort right from the seed phase, where you wait for the plant to germinate, to ensure that they get the right kind of light, heat, air, humidity, etc. It is weeks of careful observation and ensuring that pests, insects, or mold do not damage your plants. It takes quite a bit of time and money – but when the flowers are finally out there, that is the moment all your efforts pay off.

Generally speaking, marijuana plants grow in two major phases – the vegetative phase and the flowering phase. The vegetative phase is where the strains start growing from a seed to small-sized cannabis plants. This phase ends around the time the sex organs begin to appear, which is where the flowering phase begins. The flowering phase itself is divided into two parts – pre-flowering and flowering. In this article, we take a closer look at the latter. 

When one sets out to grow their own plants, they often expect them to grow quickly. However, nature takes its own sweet time. Marijuana strains can take as few as 10 weeks to as many as 32 weeks to reach the harvest phase from the seed phase. This is inclusive of both, the vegetative and the flowering phases. However, this also depends upon the strain that you are choosing to grow. If you happen to choose a fast-flowering strain, you will get your results quickly.

Over the course of this article, we take a closer look at some of the fastest flowering marijuana strains, which have a flowering phase of 8 weeks or less. These strains ensure that your plants are ready quickly and that you don’t have to wait for too long to get the result of your hard work. These are great strains for anyone who is looking forward to getting quick results because they are either short on time, or they are anxious that waiting for longer might result in pests or mold damaging their plants. 

We have chosen a fair mix of photoperiod feminized marijuana strains as well as autoflowering plants in this article to provide you with a fair mix of options. Autoflowering plants generally tend to flower the fastest – and are usually ready for harvest from the seed phase in a span of about 14 to 15 weeks and are typically considered easier to grow because you don’t have to manually reduce lighting hours in their case. However, they also tend to provide lesser yields in comparison to regular photoperiod plants, so make your pick wisely. Let us begin with the list of fast-flowering strains:

1. Strawberry Kush Feminized Marijuana Seeds

When you are looking at marijuana strains that are fast-flowering in nature, one of the first names that you should check out is the Strawberry Kush marijuana plant. This is the feminized variant of the strain from ILGM, and it carries about 75% Indica genetics and 25% Sativa genes. The strain usually takes about 8 weeks to hit peak flowering levels and is a pretty good option for people who appreciate smoking their weed with a little bit of a flavor. As the name itself indicates, the strain carries a strong Strawberry-like taste, while there’s also the classic woody and earthy flavor profile that Kush strains typically carry.

The Strawberry Kush marijuana strain is created by crossing the OG Kush marijuana strain with the Strawberry Cough strain. The taste comes from the latter, while much of the effects of the ‘high’ that you get from this strain come from the Kush genetics. This marijuana plant is a good choice for people who are looking for high-yielding strains as well, as it can provide you with pretty high yields up to 23 oz per square meter upon maturity. This is a rather impressive number. 

Let us now look at the THC and CBD concentration in the strain. This isn’t really a plant that you would want to consider if you are looking for something that carries a healing touch. However, if you want to get high and experience a strong buzz, this is a good option. The strain carries an 18% THC concentration and negligible CBD levels. It can give you a pretty strong buzz but won’t really make you nauseous while making you feel all the psychoactive properties of the plant.

Smoking this strain gives a strong body high, given that this is an Indica-dominant plant. However, it also carries 25% Sativa in it, and while you don’t really feel a ‘head rush’ like you would in classic Sativa strains, you would, however, feel a pretty strong euphoric feeling which will make you feel happy and elated. The strain is suitable for indoor as well as outdoor growing and is a fairly easy-growing marijuana plant. However, do note that while the plant does not grow very tall, it does develop a complex set of branches and you might have to use the Sea of Green technique of growing marijuana plants while growing this one.

2. Tropicana Poison F1 Fast Flowering Marijuana Seeds

Tropicanna Poison F1 Fast is another interesting name, especially when it comes to fast-growing marijuana plants. This is a strain that takes just about 6 to 7 weeks to flower indoors and gives you some very quick results. This is indeed the plant to choose if you are short on time. This is also a pretty good marijuana strain for people who prefer Indica plants which also carry a fair bit of Sativa, as this is a 60% Indica dominant strain with 40% Sativa DNA. The buds that grow on this plant are pretty dense, and when the plant matures, these buds are a good option for those who like to create extracts.  

Do note that this plant carries in it about 24% THC content. This makes it extremely potent and very strong when it comes to getting you stoned. Just a few puffs of this strain are enough to get even some of the most experienced of stoners to feel light-headed. When you smoke this bud, you will feel a strong sense of euphoria as well as a very relaxed body high. It won’t make you so lethargic that you’ll want to sleep, but you will feel this relaxed and near-floating sensation. The plant carries only about 0.1% CBD content and isn’t much for medical usage.

The Tropicanna Poison F1 Fast strain comes as a cross between Tropicanna Cookies (Girl Scout Cookies x Tangie) and RedPPOison Auto strains. Apart from being an extremely fast-flowering marijuana strain, this is also one that gives you pretty good yields. People who grow it indoors can get about 600 grams per square meter, while those who grow it outdoors can get up to about 650 grams of usable bud per plant. 

Tropicanna Poison F1 Fast marijuana strain has a rather earthy and woody flavor profile, and you will also be able to take some notes of spices and mangoes in it. Do note that as soon as the flowering hits, the plant’s smell will fill wherever you are growing it as it carries a really strong flavor profile, so you might want to keep your carbon filters ready! 

3. Critical Mass Feminized Marijuana Seeds

Critical Mass is a marijuana strain that often pops up in conversations about CBD-rich marijuana plants. However, the variant that we are looking at today is the regular high-THC variant of the plant. This is a pretty fast-flowering plant and has a flowering stage of only 6 to 8 weeks. The strain carries about 21% THC content in it on average. This is a pretty good option for people who want to smoke up and get high. Basically, this is a great strain for recreational stoners. While there’s a CBD-rich variant of the strain which carries up to 10% CBD, this one features only about 0.5% CBD and isn’t really a medical strain.

While you can find the Critical Mass marijuana strain listed on many other platforms, the one that you buy from Crop King Seeds (CKS) seed bank is the fast-flowering version, which is why we have ensured that it is listed here. This is a great plant for people who want to prepare extracts as it results not only in big buds but also ones that are pretty moist and rich in resin content – allowing you to make extracts in different forms. 

The flavor profile of the Critical Mass marijuana strain is also pretty interesting. It carries a rosewood-like smell and exhibits overall sweet notes. You can even taste some honey and citrus-rich notes when you smoke this bud. There’s an earthy and woody smell that is left behind after you’re done smoking this strain. The strain is preferred by indoor as well as outdoor growers, but indoor growers can benefit quite a bit from it, as it does not grow too tall and attains only mid-level heights. 

This is a plant that loves sunshine and prefers to avoid moisture and humidity. You might want to tie some branches as the heavy buds can cause them to fall over. The strain, as we mentioned earlier, takes about 6 to 8 weeks to hit peak flowering levels, and provides between 300 to 400 grams of yields per square meter when grown indoors. Outdoor growers can get somewhat higher yields, and the best time to harvest this cannabis plant is typically mid to late September. 

4. Green Crack Autoflowering Marijuana Seeds

This is the autoflowering variant of the green crack marijuana plant, which flowers pretty quickly. If you’re looking for some of the best fast-flowering cannabis strains, you’ve certainly got to consider this one. Green Crack usually takes close to 8 weeks to hit peak flowering levels right from the day you grow it. It is one of the fastest-growing strains here, and is a plant that thrives indoors as well as outdoors, and is a pretty good option for beginners as well as experienced growers. The strain carries 75% Sativa genetics, and about 25% Indica genes.

This marijuana plant carries 21% THC content in it and has a rather happy and euphoric high associated with it. This is a great strain for people seeking relief from stress and depression or other similar mental health-related challenges. However, this is a great pick even if you want to just sit back and enjoy the psychoactive effects of weed. The strain gives you a head rush and provides a rather creative high. There’s a strong mango and spice-like flavor profile that the strain carries. 

Typically, you’d expect a Sativa-dominant marijuana plant to grow taller, but given that this is an autoflowering plant that matures in just about 8 weeks, it doesn’t get too tall. The plant attains a maximum height of about 200-225 cm which is roughly 6.5 to 7 ft at most. The plant prefers a sunny, dry, and warm climate to deliver optimum performance – and upon being provided with the right climatic conditions, it provides an indoor yield of about 550 grams per square meter. Outdoor growers get a somewhat underwhelming 200 grams per plant. 

This is one of the best fast-flowering marijuana plants out there, which is a great pick for people who want to get a recreational buzz, or for those who wish to create extracts. While you grow this plant, you can also make use of the Sea of Green technique to get the best possible yields out of the plant.

5. Hindu Kush Feminized Marijuana Seeds

The name of the Hindu Kush marijuana strain leaves no questions about its origins, and even about its genetics. The strain grows in the Hindu Kush mountains of the Af-Pak region, and this is the area where some of the finest Indica strains of the world grow as landraces. What makes this strain even special is the fact that this is a 100% Indica-dominant marijuana plant. The flowering period of the Hindu Kush marijuana strain takes about 7 to 8 weeks, and it is an ideal strain for people who want to experience an Indica-like high in all its purity without any of the hyperactive effects that Sativa genes bring.

The Hindu Kush marijuana strain carries about 18% THC content in it. The kind of experience that you get when you smoke this strain is pretty incredible – especially if you are looking forward to relaxing. A few puffs of this strain and you will start feeling rather comfortable wherever you are. There is a very strong body high that can be associated with this strain, and it gives those who smoke it a feeling like they’re floating and weightless. The Hindu Kush marijuana strain can also make you very drowsy and sleepy if you take a few hits too many.

The strain carries a sweet and earthy taste and doesn’t really have a fruity or spicy flavor profile like some other strains that grow around the region. The Hindu Kush strain prefers growing in an environment that is both, dry, as well as warm. The strain thrives in sunlight too. You get the best results when you grow the plant indoors using the Sea of Green technique of growth. There is just one thing you need to keep in mind – this plant needs a lot of airflows as well, so make sure you are providing that. Upon maturity, it provides about 17 to 18 oz of indoor yield per square meter under ideal conditions. 

6. Strawberry Cookies Fast Flowering Feminized Marijuana Seeds

Strawberry Cookies marijuana strain drops two hints about itself in the name. Firstly, it carries a strawberry-like taste, and second, it descends from one of the cookie strains. This is one of the best options for people who are seeking a balanced high and want to experience the effects of both, Indica and Sativa genetics. The strain is 50% Indica dominant and 50% Sativa dominant, bringing the best of both worlds together. This is also a pretty fast-flowering marijuana strain, and stoners don’t really have to wait too long to get to the harvest season.

There’s over 20% THC concentration present in the Strawberry Cookies strain. This gives those who smoke it a pretty intense high. This is a purely recreational strain as it doesn’t carry too much CBD in it. There’s under 1% CBD content present in the buds of this plant. The plant can be grown indoors as well as outdoors but is preferred more by indoor growers. It doesn’t grow too tall, growing as tall as 150cm in height. This marijuana strain prefers warmer temperatures and provides the best yields when you maximize the lighting around it. The strain carries a strawberry-like flavor profile, with notes of vanilla and mint making their presence felt as well. 

Being a fast-flowering strain, the flowering takes only between 45 to 49 days and gives you quick results. Upon hitting peak maturity, the strain provides pretty high yields, though the exact quantity hasn’t been specified by the Seedsman seed bank. When you’re growing this strain, you need to keep in mind the fact that the branches can get bent or even snap due to the weight of the buds so you might have to hold them up using strings. Topping is a method that can help improve the yields when growing this plant.

7. Green Poison CBD Feminized Marijuana Seeds

Much like what we have seen in the Strawberry Cookies strain above this, the Green Poison marijuana strain is also pretty well balanced when it comes to the Indica-Sativa split. However, the major difference comes when one looks at the THC and CBD composition. This is largely a CBD-dominant strain and carries slight amounts of THC in it. Green Poison, despite what the name sounds like, is actually of great medical value and can provide a strong healing effect. This is also a rather fast-flowering plant that hits peak flowering in about 7 weeks. 

Let us first look at the USP of this strain – the fact that this carries a ton of healing properties. There’s up to 12% CBD content present in this marijuana strain, and an average of about 5% THC. It offers a THC:CBD ratio of 1:2. The strain carries only about 5 to 9% THC in it, which is pretty low, and while it will give you just a very mild buzz, it will still keep you pretty alert compared to smoking a bud that carries a higher amount of THC. The kind of high you experience would be much milder. On the other hand, having 12% CBD is pretty strong and you will experience intense healing.

Among the many healing benefits that marijuana plants carry, pain relief happens to be one of the biggest and the best of the lot. Smoking this marijuana strain will help you experience rather intense pain relief and will ensure that your bones, as well as muscles, feel relaxed. This strain is also a pretty good option for people who wish to experience a slight buzz while feeling a lot of healing properties. It is also a good option for people who want to feel relief from stress, anxiety, and other mental health-related ailments. 

When you take the first few drags off the bud that grows on this plant, you’ll feel a strong minty and pepper-like taste. There are several fruity and nutty notes that one can feel as well. In terms of It usually takes the Green Poison marijuana strain about 7 weeks to hit peak flowering, and upon maturity, it yields about 650 grams per square meter, when grown indoors. All in all a good-tasting strain that grows pretty quickly and provides a decent yield.

8. MK Ultra Feminized Marijuana Seeds

When it comes to fast-flowering marijuana strains, you might notice that most of them are either Indica-dominant, or they are an even split. The MK Ultra marijuana strain falls in the latter category. The strain carries 50% Indica and 50% Sativa genetics, giving you a very well-balanced high, and equal parts body and mind high. This is a pretty fast-growing marijuana strain, and it takes about 8 weeks to hit peak maturity levels. The strain has some strong cerebral effects and is born as a cross between the OG Kush strain and the G-13 strain. This is an award-winning marijuana plant and won the High Times Cannabis Cup in 2003. 

MK Ultra carries about 21% THC content in it. This is a pretty strong strain that can give you a psychedelic high, while also taking you into a very hypnotic phase, where you will feel relaxed and couch-locked. This is a very good option for people who just want to relax and feel all the psychoactive effects rather strongly. There isn’t much CBD content in this plant, making it purely a recreational strain. 

When you smoke the MK Ultra, you’re likely to get a mixed bag of flavors. The first and the most obvious of these tastes that you experience is that of a strong and sweet undertone. The sweet taste is a consistent feature of this strain. Other than that you’ll also notice some pineapple-like flavors and a hint of spices. This is a pretty unique flavor combination as you generally don’t see these flavors co-existing. 

The MK Ultra strain is a lot of things but it isn’t really a high-yielding plant. It produces about 6 oz per plant when grown indoors, and about double that when you grow it outdoors. This is also a good option for people who are suffering from a lack of appetite as it can help open up your appetite and make you feel pretty hungry. Keep a bag of snacks near you when you smoke this fast-flowering marijuana strain.

9. Lowryder Autoflowering Marijuana Seeds

The Lowryder marijuana strain is yet another Indica-dominant marijuana plant on this list. The plant tends to grow pretty quickly and carries impressive yields. This is an autoflowering plant, and don’t consider it to be any other autoflowering plant – this is largely believed to be among the first autoflowering marijuana plants that were created by combining the ruderalis genes to Indica/Sativa genes. The strain is a cross between a Ruderalis landrace along with Northern Lights #2 marijuana strain and William’s Wonder marijuana strain. This strain usually takes about 7 weeks of the flowering phase, making it one of the fastest-flowering marijuana plants out there.

The strain carries in it about 80% Indica DNA and 20% Sativa content. It gives an intense relaxing high and makes one feel extremely comfortable and relaxed. The strain is ideal for people who want to consume it as an evening strain after a tiring day at work. This is also a pretty good option for people who want to get a good night’s sleep and want to wake up refreshed. The strain carries only about 14% THC content in it and has a mellow and refreshing buzz. This is a great strain to smoke if you are a beginner and don’t want something that will get you too high.

The Lowryder autoflowering marijuana strain carries an earthy and pungent smell that is likely to linger around the room for a pretty long time after you’re done smoking. The strain carries a very natural and herbal sort of taste. It generally prefers growing in an indoor environment and is a plant that does not grow too tall. While growing this strain, make sure that you are keeping your grow lights pretty bright. Being an autoflowering plant, the Lowryder strain can actually withstand longer hours of lighting even in the flowering phase.

10. Do-Si-Dos Feminized Marijuana Seeds

While the Do-Si-Dos marijuana strain is a good option for people who are looking for a fast-flowering marijuana plant, as it takes only about 8 weeks to hit peak flowering levels, the main attraction of the plant is the THC content its buds carry. Do-Si-Dos buds carry a jaw-dropping 30% THC content, which gives those who consume it a pretty intense buzz. This is a 70% Indica dominant marijuana plant, which also happens to carry about 30% Sativa DNA. The strain is extremely relaxing and almost has a sedative effect on those who consume it. 

Given that it carries 30% THC content, it will deliver a pretty strong punch to those who smoke it. If you are an inexperienced stoner or someone who is smoking weed for the first time, we highly recommend to pace yourself well and take things slow here. The effects of the strain are largely relaxing and comforting, and give you a happy high. The strain also makes you feel pretty lethargic and will get you searching for your nearest couch or a pillow after a few hits. This is also a great strain for people who suffer from insomnia or sleeping disorders as it will make you feel pretty sleepy. 

The Do-Si-Dos strain requires a lot of ventilation. This is a strain that can be grown indoors as well as outdoors, but you’d need to use carbon filters to capture the smell if you plan on growing them indoors. It requires bright lights and prefers humid environments. Upon growing, the strain carries a mix of lavender, orange, and greenish-yellow shades. It has a very attractive look and is a pretty potent strain that tastes like fruits, lime, and herbs. There’s a skunk-like and diesel-like smell that it leaves behind.

Frequently Asked Questions (FAQs) About Fast-Flowering Marijuana Strains

Our readers send in a number of questions, and often these questions are repeated. We get a lot of questions about fast-flowering strains and autoflowering strains as well. We have decided to curate some of the most common and frequently asked questions together in this section so that you can understand these strains in a better manner. 

1. Are fast-flowering strains safe to smoke? Do they have any side effects?

Yes, fast-flowering marijuana strains are extremely safe to smoke. There are no side effects or problems that you might face when you specifically smoke them. However, some general side effects will persist. These include red eyes, which are perhaps the most common effect that smoking weed has on you, along with a dry mouth, feeling very hungry (AKA the munchies), etc. Some people might also feel disoriented, anxious, or nauseous. However, most of these latter symptoms are pretty rare. In any case, there are no side effects specifically associated with smoking fast-flowering strains. 

2. Which strains flower faster – Indica dominant or Sativa dominant?

While fast-flowering strains can be of both, Indica as well as Sativa family, our general observation is that a larger number of Indica-dominant strains exist compared to Sativa-dominant ones. However, there are some major exceptions, including the 75% Sativa-dominant Green Crack marijuana strain that we have listed above, most of these plants are typically Indica-dominant. There are a large number of strains that are actually evenly split and carry 50-50% of Indica and Sativa in a fine balance, but overall if you look at the larger picture, Indica strains are more prevalent among fast-flowering marijuana plants. 

3. Do fast-flowering marijuana strains carry any less THC compared to regular strains?

No, this is not true. Fast flowering marijuana strains carry pretty much the same levels of THC as other strains. In fact, if you see our list above, the Do-Si-Dos marijuana strain carries in it close to 30% THC levels, which is extremely high and you won’t even see it in plants that flower at regular speeds at times. However, there are some autoflowering plants which are low on THC compared to their regular variants. But this is something that you observe only in a few such plants, and not in all autoflowering variants. However, while the THC content is not impacted, you will notice a slight decrease in yield in these strains, particularly when you look at the autoflowering ones. 

4. Where can I buy the best autoflowering marijuana seeds?

Autoflowering marijuana seeds are pretty common and can be bought from any place that sells marijuana seeds. However, we strongly recommend buying it via online seed banks, which ensure that you get high-quality seeds which have a higher chance of germinating. Seed banks are also a safe bet because they ensure discreet shipping, and even provide refunds and replacements in case a majority of the seeds fail to germinate. Seed banks also have a larger number of options to choose from, and provide better information about the seed you are going to buy (and often about its lineage as well). 

5. Can I grow autoflowering marijuana plants outdoors?

Yes, autoflowering marijuana plants can be grown outdoors as well as indoors, and even in greenhouses. The biggest benefit of buying these seeds is that the plants that grow from them do not need to manually reduce the lighting hours in order to trigger the flowering process. Flowering in these plants begins automatically after a set number of weeks and the plants tend to mature quicker compared to regular plants. These are among some of the best fast-flowering varieties of marijuana seeds and you can find thousands of autoflowering variants out there, giving you a large variety of tastes and flavours to choose from.
