Top 5 best indoor cannabis seeds

Based on our experiences and customer reactions, we have drawn up a top 5 of indoor cannabis seeds. We have taken into account ease of cultivation and weed quality.

Critical feminized seeds

Our Critical feminized seeds are probably one of the best cannabis seeds to grow indoors. And not without reason. Critical is very suitable for extremely small spaces as they do not grow larger than 80 cm. The strain is easy to grow, features a very short flowering time and yields are quite big. When pruned at the bottom, the buds grow at the top. In this way it is possible to place up to 16 plants per m2 which can result in a yield of up to 500 grams per m2.

AK 47 autoflower

The AK-47 autoflower is one of our favourite classic strains and one of the best indoor cannabis seeds. The AK 47 autoflower is second in this top 5, but actually deserves a shared first place. Thanks to its genetics (Thai Skunk, Mexican Sativa and Afghan) the AK 47 autoflower is known for its extremely high fungal resistance and high yield. Yield can be as big as 675 grams per m2(!). The genetics are very stable and easy to grow indoors. A failed harvest is therefore almost impossible.

Amnesia Haze feminized seeds

Amnesia Haze is another classic strain and couldn’t be missing in our top 5 best indoor cannabis strains. The strain is worldwide known because of its very high THC level. Thanks to its properties Amnesia Haze is very suitable for indoor cultivation. The only “drawback” we can think of is the relatively long flowering time of 10 to 12 weeks. However, every disadvantage has its advantage. Due to the long flowering period the weed is extremely strong, the yields can reach 650 grams per m2 and both the taste and the smell are sublime. Keep this in mind, because if you’re sensitive to psychosis, it’s better to skip these weed seeds and opt for milder ones.

Northern Lights feminized seeds

Many experienced growers will not be surprised that we have included Northern Lights in this top 5. Northern Lights cannabis seeds are easy to grow. The yields from this plant can reach as much as 550 grams per m2 in a very short flowering period of just 7 to 8 weeks! That’s what we call super seeds. Moreover, the taste is appreciated by almost every cannabis lover. Haven’t tried Northern Lights yet? Then we advise you to do so!

Power Plant feminized seeds

Last, but not least… Power Plant feminized seeds. You probably won’t find the Power Plant seeds in a Top 5 ‘indoor cannabis seeds’, but from our own experience we can honestly say that this is one of the best indoor cannabis plants. This marijuana seed has all the characteristics that an indoor grower wants. It features a relatively short flowering time of 8 to 9 weeks, an extremely high mould resistance, easy to grow, a short plant height (max. 90cm) and a yield of up to 550 grams per m2. Doesn’t this plant have any disadvantages? Hardly, it requires some knowledge of scrogging to control the plant height. But once you know how to do this, it is very simple. In short: what more do you want?

The Best Cannabis Seeds For Indoor Cultivation

5 min

Growing cannabis indoors is convenient and effective. It allows for a degree of intervention and control that is hard to reach outdoors.

Growing cannabis indoors is a great way to maintain ultimate control over your crop. Everything can be micromanaged, from feeding to the intensity of light, to the much more advanced aspects of a grow. Here are five fabulous feminized seeds and five awesome autoflowering seeds for you to grow indoors.




Unlike in the past, the autoflowering strains of today are much more highly regarded, and consistent to boot. For those looking to bypass complicated light cycles, or those looking for a fast turnover, autos are a perfect option for developing high-grade weed with ease. Plants can fit into the smallest of spaces, and they’re robust and resilient as they grow. Autoflowers can also be an excellent option for those just starting out on their cannabis cultivation journey. Here are five recommendations for great autoflowering strains to grow indoors!


Super Skunk Automatic (Sensi Seeds) feminized

Super Skunk Automatic by Sensi Seeds is their second sequel to a true cannabis classic, the original Skunk #1. This 80% indica boasts pretty much everything that made the original so famous, including an ultra-relaxing and potent effect, and of course the iconic “skunky” smell that deemed her an eternal classic. Sensi Seeds crossed the original Skunk #1 with an Afghani hash plant and a select autoflower—so the girl can deliver quite a punch!

There are several things that make Super Skunk a great option for indoor growing. It is very robust and forgiving, and with a short harvest time of only 7–9 weeks, you won’t need to wait long before you can blaze up its buds. The strain doesn’t get very tall, so you can easily make some space for it in small closets, tents, and the tiniest of rooms.


White Widow Automatic (Zamnesia Seeds) feminized

White Widow Automatic by Zamnesia is another cannabis classic that has rightfully earned a huge following among cannabis enthusiasts. The girl shines with an exquisite taste, good yields, and an ever so intense high. If you wonder where she got her name from, just look to her excellent resin production. Once flowering comes to a close, plants will be covered in a thick layer of sparkling trichomes. Perfect for hash and concentrates!

White Widow Automatic is an ideal specimen for the indoors. With a height that won’t exceed 110cm, you won’t have trouble finding a nice spot for it—even if space is an issue. This plant goes through its entire lifecycle in a short 10–12 weeks. Get ready to enjoy an awesome mind and body high accompanied by delicious earthy and pine flavours.


Sour Diesel Auto (Humboldt Seeds) feminized

Sour Diesel Auto by Humboldt Seeds is what they call a next generation sativa-dominant autoflower. This isn’t far-fetched, as sativas in the past were anything but easy to grow, especially indoors. The main reason being that sativas tend to grow extremely tall and require a very long flowering time. Not so with Sour Diesel Auto by Humboldt Seeds. This girl reaches only 1–1.5m in height and delivers her juicy goods in a short 70–75 days from germination.

Sour Diesel Auto offers an amazing cerebral head buzz that’s creative and energetic, yet won’t be too intense. She makes a great daytime smoke when looking to remain productive yet relaxed. To her uplifting effect she adds a superb flavour of refreshing citrus and oak wood.


Super Silver Haze Autoflowering (Zambeza) feminized

Super Silver Haze Autoflowering by Zambeza is the ideal indoor strain for Haze lovers who don’t have much patience. Unlike its feminized sister, which requires 10–11 weeks for flowering alone, this automatic variant by Zambeza only requires 10–12 weeks from germination to harvest. Moreover, it will stay at a convenient height of only 80–100cm, making this Haze just perfect for an indoor grow tent.

Haze lovers are often surprised when they smoke this autoflowering version of SSH. Its powerful, psychedelic head high and pure Haze flavour will fool even the experienced grower, as there is pretty much no difference between her and her photoperiod sister in regard to quality. This very resinous girl is also excellent for concentrates and hash.


Northern Lights Automatic (Zamnesia Seeds) feminized

For indoor cultivars, getting to their juicy harvest in the shortest time possible is important, as this saves on energy and can make for multiple harvests per year! No such concerns with Northern Lights Automatic by Zamnesia! We gave this timeless cannabis classic our special treatment with the help of select ruderalis genetics to make it autoflowering and perfect for the indoors. Growers can now fill their bags in a super short 9 weeks from seed to harvest. As an added bonus, its height will rarely exceed 90–120cm, so the plant will fit pretty much everywhere.

Northern Lights Automatic has the same delicious taste and potency as its bigger sister. Smoke her, and she’ll deliver an amazingly relaxing body stone with an invigorating and uplifting note. It’s the perfect smoke for when you just want to chill and relax at the end of a long day!


The 5 Best Feminized Cannabis Seeds For Indoor Cultivation

If you want to decide for yourself how long to keep your indoor cannabis plants in vegetative growth, feminized (photoperiod) cannabis seeds will be for you. Growing feminized cannabis may be a tiny bit more involved, but it has the advantage of resulting in monster yields and extreme potency, and it puts your indoor cultivation skills to the test. Here are five of our very best.


Blue Dream (Zamnesia Seeds) feminized

Blue Dream by Zamnesia Seeds combines the best of Haze with that of the delicious Blueberry to bring us a feminized hybrid par excellence. Plant your seed, and the gorgeous specimen, with its purple and bluish buds, will grow to around 1.5m in height. This makes it still quite manageable and a great indoor strain. What’s more, and this is quite atypical for a strain with Haze genetics, she’ll rush through flowering in an incredibly short 9 weeks, so you won’t need to wait long until harvest.

Blue Dream delights with a mouth-watering mix of berry, citrus, and other sweet undertones. But be careful not to let its tempting flavours get you carried away; a euphoric and uplifting high that gradually turns into a very relaxing body stone will take you on a ride from the very beginning. Smoke too much, and you may find yourself in dreamland before you know it!


Big Bud (Sensi Seeds) feminized

The original Big Bud by Sensi Seeds earned its name mainly because of its enormous production potential, but this doesn’t mean you’ll find it slacking in other areas. Far from it! The feminized version is as good a producer as the regular version, and delights with the same high potency and great scent, which harbours crisp notes and spicy undertones.

This 85% indica, a cross between Afghani and the famous Skunk, flowers in a short 50–60 days and reaches a medium height. It is not the shortest of plants, but is still easy to handle and to predict. Its great taste blends notes of spices and fruit, while its strong physical stone carries the legacy of Afghani. A top chiller smoke that’s fabulous to enjoy alone or with friends!


THC Bomb (Bomb Seeds) feminized

THC Bomb by Bomb Seeds is the perfect indoor strain for those who love potent smokes. Containing 20% THC on average, with some plants containing as much as 25%, THC Bomb delivers a very powerful and long-lasting high, and also won’t disappoint when it comes to flavour and growing traits.

What makes THC Bomb an excellent indoor strain is that it grows vigorously yet compact (60–90cm) and with nice branching, making it an excellent candidate for a ScrOG setup to max out yield. It flowers over a very short 7–9 weeks, resulting in an excellent yield of up to 650g/m² in good conditions. Its high starts out as a heady sativa buzz, but after a few minutes, the indica side takes hold, easing your mind and body into the deepest state of relaxation. A perfect smoke to enjoy at night!


Chocolope (DNA Genetics) feminized

Chocolope by DNA Genetics is an almost pure sativa (95%) that is a favourite among cannabis connoisseurs. This multi-award-winning strain is one of the most popular strains from DNA Genetics, and harkens back to a time when strains with dessert flavours reigned supreme.

Despite her sativa genetics, Chocolope is not too difficult to grow. Grown indoors, the plant may get tall, but you can easily keep it in check with some trimming. Noteworthy is her astonishingly short flowering time (for a sativa) of only 8–10 weeks. It has a delicious taste that, unlike most sativas, doesn’t have the typical spicy or citrus notes. Instead, it will make your mouth water with an incredible taste of chocolate. Its effect can only be described as electric: a nice head buzz that is energetic and motivating—perfect to start your day!


LSD (Barney

LSD by Barney’s Farm is an ultra-potent indica-dominant hybrid that grows into a sturdy, robust plant with high resistance to pests and mould. Despite its compact height of 50–100cm indoors, which makes the strain very manageable, it can reward with monstrous yields of up to 700g/m² in optimal conditions.

LSD certainly isn’t miserly when it comes to potency, considering that the strain measures a whopping 24% THC in her juicy buds. However, what makes LSD a truly unforgettable cannabis experience is the high it gives you. It puts you into a deep, trance-like stone that keeps your body grounded, while sending your mind on a trippy, almost psychedelic journey—an effect that led Barney’s Farm to give the strain its name.


These are just some of the strains you can choose if you want to grow great cannabis indoors. No matter which strain you grow—autoflowering or feminized—each has something special to offer!
