    Characteristics of the top 10 best indoor weed seeds

    You can grow just about any cannabis strain indoors with the right equipment and space. However, some strains are simply better and easier to cultivate indoors. One of the most popular qualities to look for is size. After all, we often have to compromise on space, particularly if our grow rooms are small. From windowsills to compact tents and small cupboard hydroponic setups, short plants that provide decent yields are favored indoors. Many of these are autoflowers, hardy and easy-growing plants that are not reliant on the seasonal change of outdoor light. Many of our top 10 indoor plants are autoflowers precisely for this reason, meaning you can grow them at any time of the year. Autoflowers require less effort and maintenance to grow, making them a no-brainer for hobbyists with less time on their hands. Indicas, too, are more advantageous indoors, as they tend to grow out rather than up.

    Another top characteristic for successful indoor strains is immunity to mold and mildew. While autoflower strains are often more resistant by nature, there are robust photo-period strains too. High resistance to mold is essential because we’re not always able to fully control our indoor conditions. While fans and good ventilation are a requirement if you’re taking the process seriously, hardy plants give you more margin for error. If you’re planning on growing indoors through 2023 and beyond, consider the following strains that are ideal indoor varieties. They produce fine harvests that are less reliant on wide-open spaces, producing exceptional buds indoors.

    1. Zkittlez fem

    Zkittlez, or just Skittles, is a popular Indica-dominant hybrid strain that's picked up numerous accolades for its sweet and fruit-forward flavors. Don’t let its candy profile fool you; it’s loaded with some heady THC for a long and relaxing high that's sought out by connoisseurs the world over.

    Indoor growing

    Zkittlez was made for indoor growing. While some experience goes a long way in coaxing out its lusciously colored purple buds, beginners can opt for an autoflower version. The reason many indoor growers turn to Zkittlez is that its short growing profile can be easily kept in compact spaces like countertops and tents. What’s more, despite its stocky build, it produces yields of up to 700 grams per square meter. To achieve these mammoth harvests indoors, you’ll want to feed her high-quality organic nutrients and lower the temperature for a few hours at night to promote pigment variation. Many growers have great success utilizing hydroponic setups and applying yield-enhancing techniques like SOG and ScrOG.

    Smell, taste and effect

    Just like opening a bag of taste-the-rainbow candy, Zkittlez’s well-cured buds bring a joyful mix of grape, citrus, and berry aromas. The sweet and tropical flavors are layered with an earthy sourness and hints of skunk. You won’t only taste the rainbow, but reach it too. Zkittlez’ high is long-lasting and calming, offering full-body relaxation that soothes muscle tension. As such, it’s noted for its medicinal value in the treatment of symptoms of stress, anxiety, and depression. Patients with insomnia and ADHD can also turn to Zkittlez to relax.

    Wedding Cake is the only celebration centerpiece you'll ever need, offering a calming high that's best enjoyed at the backend of the day. It has won numerous awards in the past few years and is related to the ever-popular Cookies family.

    Indoor growing

    Autoflowering Wedding Cake is easy to grow and perfectly suited for novices. Compact and highly responsive to training methods like ScrOG, it adapts very well to space restrictions. It rarely tops 90 cm and can be pruned and trimmed to your needs. Just remember to move any training stressors like bands and wire by the flowering stage so as not to stunt or damage the autoflower’s stems. High-quality soil and hydroponic environments are both fine methods to encourage rich and higher potency buds.

    Smell, taste and effect

    Despite its sweet name, Wedding Cake has a somewhat funky flavor profile that tastes a little like sour fruit cake. To taste, you can expect layers of citrus, tingly cracked pepper, and wet organic soil. Wedding Cake is a potent strain that's best indulged in during the evening. It delivers a euphoric and psychoactive high that settles into full-body relaxation. These soothing qualities make it ideal for long-term sufferers of chronic pain and conditions like arthritis or fibromyalgia.

     

    3. Godfather OG fem

    Godfather OG is a modern-day masterpiece. Winner of several accolades and trophies, it's widely regarded as among the world's very best Indicas. With just one taste, you'll soon discover why this strain is popularly referred to as the 'Don of All OG's'.

    Indoor growing

    Godfather OG performs extremely well indoors, where you can keep an eye on its maintenance and environment. However, it is a fairly easy strain to cultivate and one that doesn't require much upkeep in the long run. Just be sure to water regularly and provide the highest quality organic nutrients. It grows medium in height indoors and can be easily sustained with pruning and training techniques. Godfather OG also thrives in hydroponic setups, where you can keep track of pH and nutrients.

    Smell, taste and effect

    Godfather OG possesses an intense and pungent aroma that's earthy and dank. Forest floor and pine flavors mix in on the palate with a good dollop of fruit. Dark grape and herbal notes come through with proper curing. As a king of Indicas, Godfather OG soothes and relaxes the entire body. It has become a go-to strain for medicinal consumers looking to treat insomnia, pain, and anxiety.

     

    4. Super Skunk auto

    Fans of skunky cannabis should check out Super Skunk, one of the world's top Indica strains. A mainstay of Dutch coffee shops, this super-charged Skunk #1 has received numerous accolades worldwide for its soothing high and mature variety of flavors.

    Indoor growing

    Super Skunk autoflower seeds are remarkably easy to grow. While maintenance shouldn’t be too much of an issue, it helps to trim the lower branches to promote air circulation. What’s more, growers with a bit of experience under their belt can experiment with training techniques to boost this plant’s potent yields. Super Skunk is particularly adept at growing in compact indoor spaces, where you can easily keep things under 100 cm. Just ensure proper ventilation and fans are in place to minimize the plant’s funky aromas.

    Smell, taste and effect

    Super Skunk boasts an epic skunky profile that’s musky, earthy, and sweet. Enjoy lashings of lemon and tingling spice in the smoke, alongside bittersweet pine and herbs. Super Skunk is renowned for its sedative qualities, delivering huge doses of relaxation that melt across the body. These make it a fantastic end-of-day option, but not so wise when concentration is required. As such, medical marijuana consumers can utilize Super Skunk to help relieve stress conditions and soothe pain.

     

    5. Sirius Black fem

    This stunning little Indica is among the most eye-catching indoor growing options. Renowned for its deep purple appearance and Harry Potter origins, its effects are equally enticing, delivering a full-on Indica high that calms and relaxes.

    Indoor growing

    Sirius Black is a fairly easy strain to grow and is well suited for hobbyists. Resilient to common mold, mildew, and pests, it's a hardy strain that requires minimal trimming. To achieve the strain's epic yields, consider utilizing SOG indoors. What's more, it benefits from heat manipulation to coax the plant’s dazzling purple leaves when flowering. You can keep this strain pretty compact at 80 cm, just be sure to prune or thin out the bushy lower structure to promote air contact and light penetration.

    Smell, taste and effect

    Just like its color profile, Sirius Black boasts bold purple grape flavors. These fruity notes are complemented by musky skunk and dank earth flavors. In terms of effects, Sirius Black is well-balanced, offering an overall calming and soothing high with a heady buzz to match. The strain is perfect for late-night parties or social gatherings where the Indica qualities won’t overwhelm. Medicinal patients turn to Sirius Black to help treat chronic pain, fatigue, and mood disorders.

     

    6. Green Crack auto

    This Sativa masterpiece is well-regarded for its significant THC levels. Ideal for those in search of heady creativity, Green Crack is also remarkably easy to cultivate indoors. The strain is said to have been named by the rapper Snoop Dogg, although many refer to it simply as Green Crush.

    Indoor growing

    Autoflowering Green Crush seeds are a breeze to grow. Newcomers to the scene will have little issues cultivating their prized buds. It works well in indoor environments thanks to its slight Indica heritage (30%). Rapidly flowering and simple to trim, it copes well with temperature ranges from 20 °C to 32 °C. For the best results, utilize indoor ventilation to promote good airflow and prevent mold or pests. Green Crack isn’t as greedy as other strains, so make sure not to overwater it.

    Smell, taste and effect

    Green Crack wears its Skunk #1 heritage well with its luscious citrus and pine flavor profile. There are plenty of tropical fruit notes there too, all balanced by lashings of skunk, earth, and bitter lemon. In terms of effects, Green Crack produces a significant mental buzz that's uplifting and creative. Ideal as a wake-and-bake strain, it can also be used to treat symptoms of fatigue and stress. No wonder, creatives turn to this strain to remain alert and positive throughout the day.

     

    7. Gorilla Glue fem

    One of the world’s most famous strains is also one of the easiest to grow indoors. Gorilla Glue is a go-to strain for many savvy buyers, and it has won copious awards thanks to its super-sticky buds. It remains a favorite among growers thanks to its high yields and experimental potential.

    Indoor growing

    Gorilla Glue is a dream to grow and is favored among novices and experienced green thumbs alike. It's robust and hardy, making it easy to control and manage in compact indoor setups. Still, we recommend high-quality organic soil or quality nutrients in a hydroponic system. Gorilla Glue thrives at temperatures around 26 °C and can cope with relative room humidity levels of 45 to 60%. Utilize a humidifier or dehumidifier to control this during each stage of its growth.

    Smell, taste and effect

    Gorilla Glue is related to Chem Sister and boasts a similarly chemical, petrol-like aroma. These resinous flavors give way to dark berry notes with gorgeous hints of chocolate and coffee. Gorilla Glue is beloved for its heavy-hitting high, delivering a euphoric and relaxing high that soaks through the entire body. Its long-lasting effects are particularly useful for those treating insomnia and chronic pain. It can also help in alleviating anxieties and day-to-day stresses - although too much can leave you glued to the sofa.

     

    8. Gelato auto

    Sweet and creamy Gelato is legendary. Much loved for its sweet flavors and balanced effects, it also delivers significant and consistent potency for an autoflower. See why this strain is turning heads on both sides of the Atlantic.

    Indoor growing

    Gelato is super-easy to grow in its autoflowering form. No need to wait for seasonal light changes, she'll grow in tight and compact spaces with little issue. Tents are recommended to fully control the plant's environment, monitoring temperatures of around 27 °C. Humidity is also less of an issue, just ensure room levels don't regularly exceed 60%. You can achieve significant yields by applying SOG and planting multiple seeds in a small tent setup.

    Smell, taste and effect

    Gelato’s famed creamy and sweet flavors are just the start of this rich experience. Gelato comes loaded with fruity, tangy, and spicy notes too. A true winner when it comes to taste, it benefits from at least 4 weeks of curing time. Its effects are equally tantalizing, offering a well-balanced high that’s both euphoric and mellowing. This almost equal split of mental stimulation and full-body relaxation makes it a real boon in social situations and parties. As such, it's also become a staple of medicinal consumers alleviating symptoms of chronic pain, insomnia, fatigue, and stress.

     

    9. Tangie fem

    A stone-cold classic, Tangie is a modern update of the archetypical Californian Sativa, Tangerine Dream. It counts multiple awards under its belt for its excellent quality and genetics. This is a must-try for all fans of timeless and skunky orange strains.

    Indoor growing

    Tangie is an excellent indoor option for those in search of a Sativa. While some height is required to pull it off, Tangie responds very well to training techniques like ScrOG. By trimming its lower leaves and manipulating growth, you can ensure she thrives in tent, cupboard, and even windowsill setups. Otherwise, a greenhouse will be required to let it reach its full height potential. In terms of skill, Tangie is recommended for those with at least some experience. That’s because you’ll need to regulate temperatures and trim/train more often than other strains on this list to suit your indoor grow room.

    Smell, taste and effect

    Tangie produces a mouth-watering tangerine-like aroma that follows through in the taste. These juicy orange flavors are met by other sweet citrus notes and hints of tropical papaya. It has plenty of sourness and skunkiness in there too to balance out the sweetness. The ideal wake-and-bake option, Tangie is immensely popular for its cerebral buzz. These waves of uplifting stimulation are perfect for treating symptoms of fatigue and depression.

     

    10. Critical Purple auto

    This potent hybrid autoflower is among the easiest for indoor growers to cultivate. Related to the famed Critical Mass and Big Bud, it's one of those deeply relaxing strains that blankets the body and mind. It grows rich purple flowers that glisten and bring your grow room to colorful life.

    Indoor growing

    Critical Purple seeds are simple to grow thanks to the presence of autoflowering ruderalis. This is among the most compact options out there, making it a dream for small apartments or SOG setups. You can expect heights as short as just 50 cm! In terms of maintenance, Critical Purple is also very robust and versatile. Minimal trimming is required, but thinning out the lower branches is recommended to increase airflow. These superfast growers can be finished in as little as 10 weeks, and are the perfect option for absolute beginners.

    Smell, taste and effect

    Critical Purple offers an excellent blend of sweet, floral, and earthy flavors. There's an element of skunkiness in there too to counterbalance the ripe grape and citrus.
