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.

ROYAL COOKIES
The previous strains, Critical, and Royal AK are well-established varieties and cultivated by many indoor growers across Europe for many years. Widespread popularity is often a good sign indicating the quality of a certain strain or lineage, but sometimes it’s beneficial to give new genetics a chance - a reason why we decided to list our newly developed Royal Cookies in this Top 5. This strain is based on the notorious Girl Scout Cookies “Forum cut”, an elite clone that was only available in a cannabis internet forum. Girl Scout Cookies is one of the most potent strains one could purchase in US dispensaries in recent times. Today, Royal Queen Seeds offers a stabilized seed of this Californian classic with outrageous THC levels of 23% - the highest THC content of all our strains.

AMNESIA HAZE
We had no other option than to list this incredibly potent Haze strain in our Top 5 for indoor growing. It’s simply one of the best varieties of our entire product range, and we can recommend it to anyone with a little experience in cannabis cultivation and the willingness to practice patience for 10-11 weeks of flowering. Waiting a few additional weeks compared to other strains doesn’t come without tremendous benefits regarding potency, flavours, and effects. Our Amnesia Haze gets regularly tested at 22% THC, combines haze freshness with fruity flavours, and its powerful effects resemble a parabolic flight into the stratosphere – you’ll experience a rush of euphoria together with a strong, uplifting head high that promotes a feeling of zero gravity.
