Although tall cannabis strains offer spectacular yields, they definitely require more work than your average plants. Their towering heights mean they take a lot longer to reach maturity when compared to a fast-growing yet tiny autoflowering strain. Additionally, growers should be prepared for relatively high maintenance in terms of pruning and defoliation. This slight increase in labor is all worth it though; the view of mammoth cannabis trees dominating the garden space is a sight to behold.
If you have the space and you're growing anyway, why don't grow big, bigger, biggest? Here is our top 10 tallest cannabis strains available.
Monster received its gigantic genes through a breeding project involving parent strains Mexican, Mr. Nice G13 x Hash Plant, and Colombian. This genetic medley produced a sativa-dominant strain that features 80% sativa genetics and just 20% indica. These genetics are what makes Monster so imposing in stature.
The high induced from smoking a bong bowl loaded with Monster is sativa in nature, providing users with feelings of motivation, happiness, and euphoria. The uplifting and cerebral effects make the strain a good choice before physical activity or long working hours. This buzzy effect is augmented by desirable tastes and aromas of spices and wood.
Planting this beast within a garden bed or large pot will unleash the full potential of the magnificent specimen, allowing it to explode to heights of 4m with staggering yields of approximately 2800g/plant! She has a flowering time of 9–10 weeks.
This unique specimen was birthed from a breeding project involving legendary strains White Widow and Haze. The high generated by Moby Dick is especially popular among smokers who prefer more intense and powerful experiences. The outcome is primarily a head high that brings about energetic, uplifting, and psychedelic sensations. The high is long-lasting, so strap in for the ride. The flowers offer tastes and smells of spice and lemon, which add to the intense energy of the high.
Indoor strains are capable of providing up to 650g/m² and grow to tall heights. However, their outdoor counterparts truly represent what this strain is capable of by pumping out massive yields of 1500g/plant and achieving towering heights up to 3.5m. Moby Dick features a flowering time of around 10 weeks.
This is a 100% sativa specimen that is also a landrace strain, meaning she is purely the product of her native environment. Malawi Gold has developed over centuries in the northern Malawi region of Southeast Africa, where she adapted to the stressors of her habitat. The lack of intensive selective breeding has left Malawi Gold with a medium THC content, resulting in a pleasant high that is clear, crisp, and subtle. It’s a superb smoke for users who prefer lighter highs that don’t overwhelm. Each toke is accompanied by spicy and fresh tastes.
This tall and branchy strain has evolved purely to thrive within outdoor settings and features a high growing difficulty. Indoor and outdoor plants feature medium yields and tall outdoor heights. Malawi Gold features a lengthy flowering time of 14 to 16 weeks, so some serious patience is required.
Dutch Dragon can produce varying levels of THC between 17–21%, meaning highs can either be slightly mellow or quite intense. Regardless of potency, the high always induces pleasurable feelings of alertness, euphoria, and happiness. The uplifting and cerebral effects really get the cogs of the mind turning, making this smoke a great choice when having deep conversations with friends. Dutch Dragon is also a treat for the taste buds, offering mouthwatering flavors of sweet, sour, and citrus.
Dutch Dragon produces some very beautiful flowers, featuring light green shades, high quantities of trichomes, and bright orange hairs. She has a wild and unpredictable growth pattern and therefore requires quite a bit of TLC in order to tame her. Techniques such as topping and low stress training will do the trick. When grown indoors, Dutch Dragon offers yields of 500g/m² and reaches tall heights. Outdoor plants will produce massive yields up to 1000g/plant and grow to gigantic heights. She features a flowering time of 9–10 weeks.
Jack La Mota is in part named after Jack Herer, the legendary cannabis rights activist and “emperor” of hemp. The strain was created by combining some of the most appreciated and high-quality genetics out there in the form of Skunk, Haze, and Northern Lights 5. This breeding project produced a sativa-dominant strain featuring 75% sativa genetics and 25% indica genetics.
The flowers of Jack La Mota feature a THC content of between 15–20% and a high CBD content. This cannabinoid profile makes Jack La Mota a highly medicinal strain capable of easing symptoms of chronic pain, stress, anxiety, sleeping issues, and more. The terpene profile within the buds produces fantastic tastes and aromas of citrus, pine, skunk, and fruit.
Jack La Mota can be grown with great success in both indoor and outdoor settings. Indoor plants will produce large yields and grow to tall heights, so a large amount of free space is needed. Outdoor plants will outperform their indoor cousins and churn out huge yields, achieving heights of 3m. She features a flowering time of between 11–12 weeks.
Dedoverde Haze is the lovechild of strains Amnesia and California Haze. This garden giant features a THC content that peaks at 24% with a high that hits hard. The energetic and uplifting effects of this strain serve as an excellent tool to stay productive and motivated. Such a potent hit of THC can also help on the medicinal front with chronic pain and mood issues. Dedoverde Haze offers a delightful concoction of flavor with hints of sour, citrus, pine, spice, and wood.
Indoor plants produce average yields yet reach tall heights, so be prepared to go to war with a pair of clippers and a variety of training techniques. When grown outdoors within garden beds or large pots, Dedoverde Haze puts out medium yields and reaches even taller heights. She has a flowering time of 9–10 weeks.
NL5 Haze Mist is a unique strain with traits rarely found in other varieties. Her most noticeable characteristic are flowers that emerge as huge pillaring bouquets, almost resembling slender green tendrils. These rare genetics were born out of a breeding project involving Kali Mist, Northern Lights 5, and Original Haze. A THC content of 15% leads to a mellow and clear high that is quite productive and far from overwhelming. This effect is matched perfectly by scents and tastes of sweetness, pine, and freshness.
NL5 Haze Mist exhibits 3 primary phenotypes that all feature long and stretchy growth, and respond exceptionally well to low stress training and ScrOG methods. Indoor plants grow to large heights and pump out huge yields, so be sure to have a large grow tent or spare room available. Plants cultivated outdoors explode to massive heights and put out yields that will leave your stash jars full for quite some time. NL5 Haze Mist has a lengthy flowering period of between 10–12 weeks.
Royal Moby is known for her trippy and slightly psychedelic highs fuelled by a potent THC content of 21%. This makes her an excellent smoke during concerts, festivals, and parties. She offers tangy flavors and scents of spice, lemon, and flowers.
Some serious indoor space is needed to grow this strain as she reaches heights of 140cm indoors and puts out yields of 600g/m². Outdoor plants take things to another level, hitting heights of 3m and rewarding growers with enormous yields of 1000g/plant. Cultivators will have to wait 9–10 weeks for flowering to be complete.
Mexican Sativa offers a true head high that leaves users feeling hazy and euphoric. This strain is ideally suited to making potent edibles and tinctures for when some serious focus and alertness are required. A medium THC content makes the high subtle and clear, perfect for a daytime smoke session.
