Growing cannabis indoors has unique advantages and disadvantages. Cultivators have almost complete control over the environment, and can easily regulate light, water, and nutrients. However, space can quickly become an issue, especially when growing strains that like to reach rapidly toward the light source.

Fortunately, breeders have tinkered with cannabis genetics to create varieties that are ideal for indoor growing. These plants remain short, and are easy to manage and train. They’re suitable for small grow tents, and some cultivators even go to the extremes of raising them in refurbished computer towers and cupboards for added stealth.

Why Grow Cannabis Indoors?

Indoor growing makes life easier for many cannabis cultivators. If you live in a cold climate with bad weather, or your garden lacks direct sunlight, indoor grow tents provide a safe haven. The ability to manipulate the light schedule, humidity, and nutrients with precision allows growers to raise weed on their own terms.

Growing cannabis indoors also helps weed lovers keep their herbal interest to themselves. Indoor grow tents with carbon filters will eliminate the stink and dramatically reduce the chances of facing any penalties.

Are All Weed Strains Suitable for Indoor Grows?

Technically, yes. All strains can be grown indoors—although some varieties are much more suited to this environment than others. Bushy indica and autoflowering strains rarely exceed 120cm in height, and are thus naturally compatible with small spaces.

Indoor growing also allows cultivators to take control of time (to a degree, at least). Photoperiod cannabis varieties begin to flower only when the hours of light decrease leading up to autumn. Indoors, growers can change the light cycle to trigger flowering whenever they want. Alternatively, they can extend the growth phase by keeping plants under a veg-specific light cycle.

Towering sativa strains have the potential to surge to heights of 300cm. Growers can limit vertical growth by planting them in small containers, but they won’t produce as good of a yield as strains specifically bred for indoor cultivation.

If you’re planning to grow weed indoors, consider the strains below. They’re ideal for small spaces and produce fantastic harvests.

Sinsemilla Superhero — HulkBerry

Our talented breeders created HulkBerry after asking themselves, “What would the perfect indoor strain look like?”. Following some careful consideration, they agreed on three key traits: a medium size, excellent productivity, and sky-high levels of THC. To achieve this outcome, they crossed parent strains OG Kush and Strawberry Diesel. The emerging polyhybrid, named HulkBerry, ticked all three boxes, and then some.

Overall, HulkBerry features 65% sativa genetics and 35% indica. She produces slender yet dense flowers boasting vibrant shades of green, yellow, and orange. Yet, most noticeably, her buds are drenched with a viscous resin exuded by an abundance of trichomes. This gooey substance contains a wealth of valuable phytochemicals, including an impressive THC content of 27%. Beginner and veteran smokers alike would be wise to take things slow and sensibly when trying these buds for the first time. It only takes a couple of tokes to feel her electrifying high take hold. Adding to this, her refreshing terpene profile provides notes of citrus, diesel, herbs, and pepper to make every hit go down a treat.

So, how exactly does HulkBerry perform indoors? You can expect plants to reach a maximum height of 140cm. However, if you’re low on space, the use of LST will keep plants at a compact 80cm. After a flowering phase of 9–11 weeks, you’ll need enough stash jars to store 400–450g/m².

Shoot for the Stars — Royal Skywalker

Royal Skywalker will launch your brain into hyperspace while lighting up your taste buds. Even if you feel like a Padawan when it comes to indoor growing, Royal Skywalker provides an easy growing experience; she’ll help you on your way to becoming a green-fingered Jedi Master in no time. This slightly indica-dominant cultivar possesses 60% indica genetics and 40% sativa. In an attempt to create a timeless indoor cultivar, our breeders crossed the legendary Blueberry with Mazar.

Royal Skywalker draws growers in for various reasons. Many feel the allure upon seeing pictures of her unique flowers; shades of dark green, almost bordering on black, are simply irresistible in their otherness. Of course, most cultivators opt to grow this plant for her high THC level. A content of 25% means it doesn’t take much to feel a surging effect take hold. The result? A powerful stash that lasts much longer than one composed of weaker flowers. The cherry on top is Royal Skywalker's scrumptious terpene profile, which features notes of blueberry, citrus, and pepper.

If you’re looking for an easy indoor growing experience, Royal Skywalker fits the bill. As soon as you flip your lights to a flowering schedule, this plant will get hard to work forming buds over a period of 9–10 weeks. By the end of this time frame, be prepared to trim and dry up to 600g/m² of frosty flowers.

Tastes of Nature — AMG

AMG, aka Amnesia Mac Ganja, belongs in your grow tent for a variety of reasons. Our breeders specifically engineered this variety to be cultivated within four walls. Combining storied and world-renowned genetics in the form of Amnesia and Mexican Haze, AMG expresses an 80% sativa-dominant profile, making her one of the few sativas that thrives under grow lights.

AMG has a lot to offer aside from good indoor growing attributes; this sativa hybrid also produces an impressive THC content of 22%, which lands a heavy psychoactive blow when it comes time to smoke or vape her buds. It won’t completely melt your brain, but it certainly won't disappoint. Gear up for a long-lasting cerebral experience that will have you reaching for your creative implement of choice, or calling up old friends. AMG’s terpenes synergise with this psychoactive cannabinoid to produce a grounding feeling—not to mention appealing flavours of citrus and earth.

In true sativa fashion, AMG has a comparably lengthy flowering time of 10–11 weeks. Though she requires a bit more time to bloom, this productive lady offers up to 500g/m² at the end of the process. Despite her great return, plants rarely exceed a height of 120cm. If you’re particularly pressed for space, consider main-lining and LST to keep her at an easily manageable height of 80cm.

Royally Productive — Mother Gorilla

Mother Gorilla provides such a euphoric effect that she could even tame the swinging fists of the most agitated silverback. Aside from making you feel like a million bucks, this strains ticks all of the boxes of an excellent indoor variety. She’s super compact, highly productive, and relatively quick to flower. Overall, she offers everything you need if you’re in search of something that will fill your stash jars without taking up too much space in the grow room.

Mother Gorilla features a 70% sativa-dominant genetic profile, and descends from cannabis royalty in the form of Gorilla Glue 4, a strain from the US known all over the world for its striking potency. To create Mother Gorilla, our breeders crossed GG4 with Reina Madre. The progeny features beautiful green-purple flowers, a THC content of 23%, and a complex terpene profile that exerts flavours of chocolate, earth, herbs, Skunk, and sourness.

Many people opt to grow indoors for stealth purposes. Therefore, it makes sense to cultivate plants that are easy to conceal and tame. Through the use of LST and other training techniques, growers can keep Mother Gorilla at a clandestine height of just 60cm. Even at this size, plants are still capable of producing up to 500g/m² over a flowering time of 9–10 weeks.

If you’re somebody that enjoys a booze-filled beverage at brunch, you’ll know exactly what a sip of mimosa does to the taste buds. The synergy of champagne and orange sends the nerve endings in the tongue into overdrive while the bubbly booze stimulates the mind.

Meanwhile, a THC content of 22% works swiftly to uplift the mind and relax the body. Whether you’re enjoying her during the morning or early afternoon, she’ll quickly put you in the perfect mood for socialising, creating, or doing household chores with newfound motivation.

Thankfully, achieving a stash of these potent flowers takes little effort. Indoors, Mimosa peaks at a short height of 80cm; apply some light training and limit pot size to keep her at just 60cm for peak stealth.
