Buyer’s Guide to the Best Indoor Strains

A large number of marijuana strains continue to be grown indoors, partially because of the societal taboos, and sometimes due to draconian laws surrounding marijuana. In any case, this has led to a large number of ‘indoor strains’ springing up over the years. The cannabis plant by itself is one that grows outdoors in nature. But over the years there are some special strains that have been cultivated which can thrive indoors as well! Here’s a buyer’s guide which will help you find the best indoor strains of cannabis – which you can grow in the comfort of your grow tent!

• Indoor Strain vs Outdoor Strain

When you are selecting the strain for growing indoors, you need to check with the seller if it is indeed an indoor strain or an outdoor strain. Growing an indoors strain outdoors and growing an outdoor strain indoors is going to have an unwanted impact on the plant, as it won’t be able to cope with the surroundings. There are some outdoor strains that can be grown indoors by simulating the environment, but the reverse is not true. Hence, you need to check if the strain that you have chosen is an indoor strain or an outdoor strain.

• Temperatures Needed

Geography-specific strains are used to the temperatures of the region where they grow in. However, if you try to grow an Afghan variant in the US soil, you are going to put in a lot of effort in ensuring that you are recreating the right kind of temperature for the strain. There are some strains which thrive in hot temperatures while others need a more moderate setting. Make sure you know the temperature requirement of your strain, and buy a heater or a cooling device based on that to ensure it gets optimal temperature conditions and provides the maximum possible yield per square foot.

• Humidity Settings

Apart from the temperature, another thing that you need to consider is the humidity in which the plant is growing. Indoor strains often need to be accompanied by humidifiers or dehumidifiers to provide them the ideal humidity levels. Check what kind of humidity your plant likes – is it a plant that loves moisture in the air or is it a plant that prefers an arid climate. It is based on this data that you should get a humidifier/dehumidifier to ensure that your plant is getting the ideal conditions for growth.

• Lighting Requirements

Growers need to account for one more thing when choosing the best indoor strains – their lighting needs. Indoor plants generally have a higher lighting need compared to their outdoor counterparts. This is because you need to simulate outdoor conditions in an indoor setup – and that often requires intense lighting, which replaces the natural light of the sun. Make sure you’re getting full-spectrum lighting, and that the light isn’t so hot that it damages the plants. You also need to change lighting schedules based on the phase of growth your plant is in. 

• Understanding the Nutrition

When you are growing your plant indoors, you need to provide it with proper nutrition as well. It needs not only a good and fertile soil to grow in, but it also needs a soil that is rich in inorganic substances. Besides that, you need to know the NPK requirements of your plant – when does it need more of which nutrient, and when do nutrients need to be reduced, and when do they need to be stopped. Understanding this feeding cycle as well as the type of nutrients that you are going to provide to the plants is quite important for indoor strains. 

• THC/CBD Concentration

THC is the primary psychoactive component present in the cannabis plant and is responsible for getting the stoners high. When you talk about a strain that gives you a strong hit, you’re basically referring to a strain which has a high level of THC concentration. Similarly, a strain that offers a mild hit has a low THC concentration. THC is generally expressed in percentage and your seed bank will let you know upfront about what kind of THC% you can expect from the strain.

Similarly, CBD is the primary medicinal compound and the higher the CBD%, the more medically beneficial this strain is going to be. High-CBD strains are generally considered great for pain relief, reducing inflammation, healing the gastrointestinal tract, reducing blood sugar levels, and for more such medical benefits. 

• Taste and Flavor

The taste and flavor of the weed that you will be smoking tends to matter a lot. Some people like to smoke weed that tastes and smells strong and pungent. Others prefer a milder and sweeter smell, such as berry-flavored and pine-flavored weed strains. There are hundreds of other taste/flavor combinations out there. The taste and flavor of your strain largely depends on their genetics – if the parent strains carry a certain taste/smell, the offspring will also carry some of their traits forward. This is something a lot of people like to consider before they choose the indoor strains that will suit their needs the best. 

• Autoflowering Strain or Regular Strain

Another thing that one must keep in mind while choosing the right strain for themselves is the ease of growth. If you are a novice grower, or someone who hasn’t really grown a lot of weed in the past, we recommend you to check out autoflowering strains. We suggest these strains to new growers because here you won’t have to worry too much about getting the lighting right, or even wait for a long time for the plants to fully mature, because autoflowering plants mature in a set amount of time (about 8 to 10 weeks) regardless of the lighting. However, these plants also have a low THC/CBD content and a lower yield per square foot, but that’s a trade-off you make for the ease and speed of growing weed.

• Yield per Square Foot

One final thing that you always need to keep in mind is the yield per square foot that you would be getting from the strain. Not all strains are high-yielding, and particularly when it comes to indoor strains, they are generally seen to provide a lesser yield per square foot when compared to an outdoor strain. Hence you might want to just total out all the costs – including the cost of equipment, the cost of lighting, electricity, and the cost of nutrients, etc. and then decide if you want to grow your weed or would you rather prefer to buy it from the dispensary.

Conclusion

If you are considering looking into the best indoor marijuana strain, we hope this article answers all your queries and gives you an outlook into some of the best options. Just keep in mind that when looking into the indoor strains, you need the criteria that need for optimal growth. If you fail to provide the plants with the basic needs to the plants in an indoor setting, they will succumb to their destruction, providing you with no yield in the end. So, familiarize yourself with the requirements first and then invest in a good-quality strain for indoor growing.
