And what are the best strains to grow indoors in 2024?
Don’t worry, we’ve done the searching for you. Let’s cover each contender for the title of best indoor strain for yields and potency to get you started off on the right foot.
Green Ninja
Green Ninja is an Indica-dominant feminized variety that checks off almost every factor ideal for indoor weed. The genetics developed by Heavyweight Seeds have resulted in a low-odor marijuana strain, and one that’s also incredibly stealthy with its short height and small stature. Even better, with these indoor marijuana seeds, after just 60 days of flowering, you’ll be treated to nearly 500-500 g/m2 (17-19 oz/ft2) of potent bud. It’s not just potent in terms of its 22% THC, either – Green Ninja also boasts levels of 1% CBD for therapeutic healing. To top it all off, this strain will satisfy indoor growers with its low maintenance when it comes to nutrients and training, making it one of the best indoor marijuana seeds around.
Royal Gorilla
Are you seeking the best indoor cannabis strain with high THC levels? Then Royal Gorilla might be the beast for you. This 50/50 balanced hybrid, developed by Royal Queen Seeds, is an award-winning feminized variety for good reason. Royal Gorilla is a popular strain known for its high quality, and it grows optimally in small containers, making it ideal for indoor weed grows while still providing yields of up to 550 g/m2 (19 oz/ft2) and THC levels topping at 26%. She's also quite hardy in nature and thrives with the use of the sea of green technique implemented in small spaces, offering a short flowering period.
Tutankhamon
Tutankhamon, aka King Tut, is everything you need when it comes to the very best indoor marijuana seeds. This potent Pyramid Seeds strain, available in feminized seed form, produces high levels of THC nearing 30%, making it suitable for frequent consumers or those with high tolerance levels. King Tut reaches heights of only 5 feet (1.5 m), making it ideal for indoor weed environments, even for growers with limited growing experience. After just 60 days of low-maintenance flowering time, you can expect yields pushing 500 g/m2 (17 oz/f2) – a number worthy of the best indoor marijuana strain. This strain is known for its earthy flavor and Sativa-leaning effects.
Tangie’matic Auto
Tangie'matic Auto (Fast Buds) - Autoflowering
- 23 %
- 400 - 550 g/m² indoors
50 - 250 g/plant outdoors - Euphoria and flight of fantasy
This feminized autoflowering strain, Tangie'matic Auto, produced by FastBuds, is unquestionably one of the best Sativa strains to grow indoors. It's a great option for growers who aim to experience powerful effects within a short timeframe of 9-10 weeks. Tangie'matic Auto is celebrated not only for its unique scent but also for its XL harvests, making it a standout choice for indoor cultivation. With genetics renowned for delivering exceptionally high yields of up to 650 g/m2 (22 oz/f2) in optimal environments, it consistently ranks among the top strains for indoor growing. Its compact height of just 80-130 cm likewise makes it an ideal choice for indoor cultivation, although be sure to use appropriate grow lights to maximize those XL harvests.
Mimosa X Orange Punch
You'll be dying to burn Mimosa x Orange Punch as you watch her massive yields grow. This indoor cannabis strain, developed by Barney's Farm, is a dense breed that can produce a whopping 700 g/m2 (2.3 oz/ft2) in just 55-60 days of flowering. A well-balanced hybrid, this strain offers 65% Indica with a still-generous 35% Sativa influence, while also delivering high levels of THC that reach a whopping 30%. Mimosa x Orange Punch thrives in controlled temperatures and is considered one of the biggest-producing strains to grow indoors. Because of her densely packed buds, this happy indoor weed strain benefits from proper ventilation to control humidity.
Auto Orange Bud
To be the best indoor strain, shape and ease of growth are vital – both characteristics that the fruity Auto Orange Bud can deliver on. This feminized autoflowering variety, developed by Dutch Passion, rewards indoor weed growers with yields up to 500 g/m2 (1.6 oz/ft2) after growing in a perfect Christmas tree shape. Auto Orange Bud's structure and size are ideal for beginner growers, yet her complex effects and 26% THC are suited for high-tolerance users. While it grows well outdoors, Auto Orange Bud prefers staying indoors to maintain control over the environment, including the light cycle, ensuring a flowering period of less than three months. Due to the weight of her buds, some support will be necessary, so be sure to leave ample room in your indoor garden for staking.
Monster Bruce Banner
Another one on the list of the best marijuana seeds for indoor growing is called Monster Bruce Banner, so you better believe you'll be treated to some monstrous yields. This Sativa-dominant and feminized strain, developed by Monster Genetics, is a cross of two classics, OG Kush and Strawberry Diesel, that produces reliable results when grown indoors. As one of the best indoor strains, she reaches heights safely under 150 cm (5 ft) yet produces yields of up to 700 g/m2 (24 oz/f2). While Monster Bruce Banner may require some extra work with trimming and pruning to contain her height, her potent results of 25%+ THC levels are totally worth it. Thanks to its uplifting haze, Monster Bruce Banner is a perfect daytime strain.
Caramelo Early Version
Caramelo Early Version is another great choice as a top-notch indoor marijuana strain. Developed by Delicious Seeds, this weed tastes just as good as it sounds. This feminized variety is not only award-winning for her potent THC levels but is also ideal for growing indoors. Caramelo Early Version is highly resistant to mold and pests that can arise in indoor environments, which means these cannabis plants can be kept close together while remaining healthy and outputting maximum yields. Thanks to its autoflowering characteristics, expect to be rewarded with 450 g/m2 (15 oz/f2) in just 45 days. Caramelo Early Version provides a calm, Indica-dominant experience with euphoria, relaxation, and pain relief, suitable for all-day use.
Gelato Auto
Despite the balanced Indica to Sativa ratio in her genetics, Gelato Auto is an autoflowering plant with a pronounced Indica structure. Ideal for discreet indoor growers with limited space for cultivation, this strain stays compact throughout the whole cycle and reaches a maximum of 110 cm (44 inches) in height. Another characteristic that makes Gelato Auto the best indoor strain for some growers is the fact that despite its short stature, it brings noteworthy yields of up to 600 g/m2 (1.96oz/ft2). Easy to grow in controlled indoor environments, Gelato Auto finishes its cycle in just 60 to 65 days to bring you buds featuring heavy trichome development for incredibly smooth, creamy tokes – rare for autoflowers – 26% THC, and energetic, creative effects.
Purple Juice Auto
Purple Juice Auto, developed by Herbies in cooperation with Spanish breeders, is among the finest indoor cannabis seeds on the market and is particularly well-suited for hydroponic cultivation. These seeds require minimal effort from the grower yet yield up to 550 g/m2 (1.6 oz/ft2) in under 10 weeks from seed to harvest. Thanks to the deep purple coloring of this strain's buds, even first-time growers can impress anyone toking on their homegrown bud. Providing Purple Juice Auto with nutrients will significantly boost your yields, and controlled lower night temperatures toward the end of the cycle will enhance the hues even more. Ultimately, you'll not only enjoy the impressive appearance but also experience a clear-headed, uplifting, and euphoric high.
Godzilla Cookies Auto
If you’re looking for the best indoor strain for yields and potency, there’s going to be no candidate better than Godzilla Cookies Auto. These indoor marijuana seeds combine all the benefits of autoflowering genetics with a crazy THC level of 27% – something not many photoperiod strains can boast. Expect absurd levels of trichome production, making this strain a great candidate for producing hash, cannabis oil, and other concentrates. Godzilla Cookies Auto remains short throughout the growing cycle, usually staying under 1 m in height (3’3”), and even that can be controlled with light LST.
