How to Select the Best Indica Strain for Your Needs

As you’re reading this, you might be thinking that any of the latest marijuana strains will suffice for your grow room

Not so fast. Not all weed strains are made alike – nor are all indica weed strains. Even the very top indica strains differ, so it’s important to know exactly what you are getting into when you’re looking for new varieties to try. 

Why Indica?

People steer toward the purest indica strains for one reason – indica produces plants that grow short and produce dense buds. They tend to have a heavy, relaxing effect, while sativa tends to be more easy and upbeat.

Not sure which way you want to go? Don’t worry – you can easily choose one of 2020’s top indica strains that’s also a hybrid. Also known as an auto-flowering strain, this cross provides all the benefits of indica weed strains with all the best features of the latest sativa strains, too.

Indica is an easy plant for beginners to cultivate. It grows well without a lot of heat and actually performs better in tehc old, too.

How to Choose the Best Indica Strain for Medicinal Use

Once you have decided that indica is the variety you would like to grow, you next need to settle on a strain. The easiest way to do this is to decide whether you will be growing indica for medical or recreational use

If you’re struggling with anxiety or seizures, you will want to choose an indica strain that contains low THC and high CBD. THC at a high level can actually make anxiety worse, so steer clear. 

If you are in chronic pain, you might want to choose a strain with plenty of cannabinoids, as these relieve pain. Look for something with lots of CBD like Northern Lights. If you have nausea or need to stimulate your appetite again, however an indica strain with high THC will be best. 

Now, if you don’t need indica marijuana for medicinal use but instead want to experiment recreationally, you have a bit more leeway. If you want more energy or a psychedelic effect, choose something with lots of THC but low CBD. These are uncommon among indica strains – you will have better luck with a sativa strain. 

Looking for a more sleepy effect? Indica is the way to go. You can choose a top indica strain with high THC and medium amounts of CBD, like Bubba Kush. This will be the perfect choice for helping you nod off. 

The Best Environment For Indica Strains

Indica is one of the best types of marijuna you can buy if you are growing indoors. The tallest indica will ever grow to about four feet. In addition, indica plants tend to have fewer branches that are also much shorter than those of the standard sativa plant. 

Despite the fact that indica and sativa strains came from the same species, there’s a lot of variation between the two. Because they were replaced in different geographic regions, the two have different tolerances when it comes to the environment. For example, indica does best in cold areas of high altitude. It originated in the Hindu Kush mountains of Pakistan and Afghanistan. Sativa, on the other hand, was cultivated in a much warmer environment. 


One of the most important features to consider when you are shopping for indica dominant strains is the smell. If you are able to smell the weed of the strain you want to purchase, you will be better off because you will know what kinds of compounds are in the product. Also known as terpenes, these are found in every strain and give you a good hint as to what the pot will taste like.


Some strains of indica have unique hues that are not to be missed. These often don’t do much for the flavor or smell of your indica, but they can be more fun to grow. Most natural hues are bright green, dark purple, and gold. However, sometimes indica can be bleached if it left too long in the sun. When you are growing your own indica, make sure this doesn’t happen, as it can affect the aroma.

Size and Shape

Choose a plant with large nuggets, as they will likely be more potent than small ones. This isn’t always true, but often, size correlates to potency. Shape is also important, as this points to how the plant was cultivated. Often, growers trim leaves off the plant to help it stay pruned and growing effectively, so if you are looking at the pictures of a cultivated plant to get an idea of what its seeds will produce, don’t always assume it will look just like the pictures when you tend to your own plant.
