Top 5 Cannabis Strains for Indoor Growing

Indoors or outdoors, that is the question. Wondering which set-up to choose and which strains work best in which environment? Fear no more and read all about the benefits of growing cannabis indoors and get to know our top 5 strains for indoor growing.

There are quite a few factors to consider when choosing which strains to grow, especially if your set-up is indoors. You’ll have to compare flowering times, yields, effects and flavours, amongst other things. Growers will often land on their favourite strain after extended trial and error, and it can be an expensive process. We at Royal Queen Seeds, fortunately, have some information that can make the decision a bit easier.

We carry a wide variety of seeds, and each of them has something special to offer. Whether they’re indoor or outdoor strains or whether they’re indica, sativa or a pleasant hybrid, there’s quality across the board. However some varieties perform better than others in an indoor grow. That’s why we’ve decided to put together an updated list of the 5 best cannabis strains for growing indoors. Don’t take this as a full list of the best choices, though. In fact, we strongly encourage you to check out our website, where you can find even more gems.

WHY GROW INDOORS?

You may be wondering what the benefits of growing indoors are. Does it have an impact on how the plants grow? Is it better than outdoor growing? The answer to both those questions depends on the strain you select. Some will thrive in the indoor environment, others won’t reach their full potential. Indoor growing in general has quite a few advantages over growing outdoors.

For starters, you can control the climate of your environment. When you have this power in your hands, you can optimize the temperature to match the needs of whatever strain you’re growing, which is a major advantage. Plus, you can keep on cultivating throughout the year since change of seasons will not affect your grow. Keeping with the theme of control, being in charge of the cleanliness of your growing area is a plus, since keeping your product free of germs, parasites, and other harmful intruders is an easier task indoors. Also, an indoor set-up means much more discretion. In short, if you’re living in a rough climate or prioritize cleanliness and privacy, indoor growing is for you.

ARE ALL STRAINS SUITABLE FOR INDOOR GROWS?

The short answer to the first question is “Yes.” The slightly longer answer is, “Yes, as long as you can maintain the proper climate, lighting, etc.”

The viability of all strains outdoors is a different story, though. The main reasoning for this is down to plant sensitivity. If you live in a colder climate, many plants you’d normally be able to grow outdoors wouldn’t be able to stand the chill. Beyond climate, there’s the issue of pests. If some bugs happen to find your plants defenceless outside, they’re as good as gone. If you try to get rid of the pests with pesticides, though, the quality of your plants drops harshly.

CRITICAL

We like to think of our Critical as the perfect all-rounder and recommend it to outdoor growers, novices, and anyone aiming for extremely high yields in a short flowering period. Indoor growers can profit from a huge production that exceeds indoor yields of 600g/m² in some cases, a strong narcotic stone due to average THC levels of 18%, and a highly stable genetic background consisting of Afghani and Skunk genetics. What makes this strain one of the best choices for an indoor grow? Well, no other variety from the Royal Queen Seeds product range is capable of yielding higher in a short flowering period of 7-8 weeks. If you’re looking for a vigorous and resilient strain that won’t cause any trouble other than confronting you with large amounts of high-quality cannabis – Critical is your choice.

ROYAL GORILLA

It was once only available to smokers in the United States. Royal Gorilla has since crossed the pond, allowing for its amazing traits to be enjoyed by the growers and smokers in Europe. A clean split between indica & sativa, Royal Gorilla provides a wave of cerebral relaxation with an impressive 24–27% THC. This is a more complicated blend, combining Sour Dubb, Chem Sis and Chocolate Diesel. Her taste finds roots in the forest, showcasing pungent hits of earthiness and pine and it will grow beautifully away from the great outdoors. Royal Gorilla will take about 9–10 weeks to flower. But once that happens, you’ll see hefty buds with bright green leaves, with so much resin they shine in the light. The plants reach 90–160 cm and bear respectable yields of 500–550g/m². This strain produces superb quality and will definitely not disappoint.

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?
