The 10 Strongest and Best Sativa Strains in 2021

Strongest and Best Sativa Strains

There’s a difference in the way a common man looks at weed vs how a stoner looks at weed. For the untrained and uninformed eye, weed is just a herb that is to be smoked. However, for a stoner – they need much more than just the green stuff. They need to know exactly what they are smoking! There are two major strains of marijuana – Indica and Sativa (as well as a third, which is a hybrid of the two). This article is about the latter, where we will discuss some of the strongest and best sativa strains out there.

Each of these cannabis strains has its own different varieties which offer different THC/CBD concentrations, as well as a different taste, texture, and feel depending on how they have been grown and where they have originated from. Indica and Sativa strains are primarily differentiated on the basis of the kind of ‘high’ they provide. All the strains that we have discussed below are in the Sativa category and provide a similar kind of a high yet there are some small differences which we will highlight in the description.

Before we head into our list of the best sativa strains to smoke in 2021, we shall also discuss in detail the difference between the indica and the sativa strains of weed and what makes them special. After that, we examine the best names in the markets along with a quick link to purchase their seeds so that you can start growing them today! We hope that by the time you reach the end of this article you will be able to make a detailed and well-informed choice about what strain of sativa weed you wish to smoke.

Know the Strains: Sativa vs Indica

Sativa and Indica are the two most common terms you hear when talking to stoners. These, as explained above, are strains of weed. Let us observe some differences between the two so that you get a better idea about what these strains are –

The first basis for the difference between these two strains of weed is where they originate from. The place where these grow to have different kinds of soil, different kinds of temperature and humidity and hence they get their distinct properties from where they grow. Sativa strains are generally found in places where the days are long and the temperature is hot and arid. Western Asia, Central America, and Africa fit the bill the best.

If you look at the indica strain, it is grown in places which have cooler climates, where days and nights are almost equal, and the climate is very humid. The best example of this is the Hindu Kush mountain range in Afghanistan, the upper reaches of Pakistan and the Indian Himalayan belt where the temperature and sunlight are just perfect. Besides this, this weed is also found in some colder regions of Turkey as well.

  • Physical Appearance

The way these plants look is also quite different and is a major ‘tell’ about which is which. When you take a look at the sativa plant, you will notice that it is thinner and taller when compared to the indica strain. How tall? Quite tall! These plants can grow up to 12 feet or sometimes even taller – which can be quite a nuisance for indoor growers, and hence these are usually grown outdoors. The stage from the seed to a flower takes a longer time when growing a sativa plant than compared to an indica plant.

On the contrary, indica plants are just the opposite. They are the perfect plant to grow indoors and they are thicker and bushier – but not as tall. Indica strain of marijuana can have plants that grow up to 6ft/7ft in height but rarely go beyond that. This strain, however, is greener and more leafy in comparison.

  • THC and CBD levels

This is another major thing that needs to be considered when discussing the differences between indica and sativa strains of the cannabis plant. The THC and CBD concentration in the plants decide what it is going to be used for. A plant with a high THC content is generally preferred by those stoners who want to get ‘high’ and want to smoke it for recreational purposes. Strains rich in CBD are consumed by those people who want to make use of its medicinal properties.

Generally speaking, Indica strains offer a higher CBD volume in comparison to Sativa strains. However, this can actually vary from sub-strain to sub-strain. Sativa plants usually have a much higher THC level than CBD content and are thus consumed by people looking to get a quick ‘hit’ rather than for its medicinal benefits.

  • The Kind of ‘High’

Smoking different kinds of marijuana plants can give you a different kind of a ‘high’ too. There are two kinds of effects that these plants generally have – either they can give you a very relaxing and tiring sort of a feel, or they can get you to energize and let your brain rush. These are called ‘body high’ and ‘mind high’. These depend upon the chemicals present inside the plant and also depend upon the geographic and climatic conditions where they are growing.

When you look at this factor of differentiation between the two strains, you’ll notice that the sativa strain gives you a mind high – a creative rush and a refreshing, energetic vibe. This is in direct contrast with its counterpart – the indica strain of weed, which gives you quite a relaxing ‘body high’, post which you’ll feel like just lazing around and chilling on your couch! This is why people generally tend to see the sativa strains as a day-time strain while the Indica strains are seen as a nighttime strain, so that you get relaxed and can sleep better.

How to Choose the Best Sativa Strains – A Buyer’s Guide

Now that you know which are the ten best options that you have and you can buy off the internet in just a few clicks, let us also look at some of the things that you must keep in mind while making your choice. Consider this as a buyer’s guide for buying the right kind of sativa strain for all your needs:

  • Taste: the seeds that you are planning on buying need to offer you the right kind of taste and smell that you are looking for. Many sativa strains are specially bred to have a specific kind of taste. Some of them are berry-like, then there are others which are more citric, some have a vanilla flavor, while there are some which retain the natural earthy taste. Choose yours based on what you prefer!
  • CBD/THC Ratio: one major thing to consider is the CBD and THC% in each of these varieties that you see above. Each strain has a different THC/CBD combination which gives it a unique property. A high THC plant will give you a higher ‘high’. For people who are new to smoking up, we suggest choosing something which offers a low THC percentage as it might be a comfortable experience for you to ease into a ‘high’ and gradually crank it up. Higher CBD numbers mean better medicinal benefits.
  • Growth Cycle: Growers must know how long their plant takes to fully mature from being a seed to the flowering stage. Some plants mature faster while others take a long time. Make sure you know that about your seeds before you decide on making the final purchase! Moreover, also make sure you know how tall your plants are going to grow before you buy them. You don’t want to end up with 12ft plants in a 7ft grow tent.
  • Autoflowering and Feminized: Make sure that the seeds you are getting are feminized as the male trees will be of no use (unless you are a breeder). Autoflowering is optional but a great choice for those growers who are still new to growing weed as it is easier for them to manage these auto-flowering plants.

Which is Better: Indica or Sativa?

The honest answer to this question depends upon what you as an individual prefer. If you are looking forward to smoking something that excites you or something that relaxes you. Are you looking to grow tall plants outdoors or small plants indoors? Are you someone who prefers a body high or a mind high – is it medicinal benefits you are looking for? How experienced a grower are you, what kind of a taste do you want, etc. There’s just so many factors and variables that come into the play that it actually becomes quite hard to decide which is the winner in the indica vs sativa battle. We agree that it sounds like a cop out but there is no answer to it! It is totally your call in the end!

Frequently Asked Questions about Sativa Strains

Here are the answers to some of the most common and frequently asked questions about sativa strains of marijuana

1. Can Sativa strains get me more ‘high’ than Indica strains?

While the answer, generally speaking, is ‘yes’, the fact is that you need to look into some details. If your sativa strain has a lower THC% than compared to the indica strain, it will not get you as high as the other one. However, the kind of high that you get when you smoke sativas is almost always a ‘mind high’ which is what most recreational users are looking for.

2. Can smoking sativa strains make me more creative?

Given that you get a mind high, smoking a sativa strain will unleash your thoughts and potentially make you think in a much more broader perspective than you would otherwise do. Many artists and entertainers have, on record, claimed that weed makes them more creative. However, realistically speaking, this is not 100% accurate – it only amplifies your existing thoughts and does not place new and creative thoughts in your head.

3. Are there any side-effects of smoking a sativa strain?

If you are looking forward to sleeping after a tiring day, you might not want to smoke the sativa strain. This is because smoking sativa buds generally gets you quite a rush of thoughts in your head and makes you feel more energetic and excited. Besides this, the only after-effects or side-effects that need to be considered are potentially those of a dry mouth and red eyes, which is common with most other forms of weed too.

4. Which is the best place to order these seeds from?

For anyone looking forward to ordering sativa seeds, we strongly recommend you buy them via the links that we have provided above along with our seed reviews. However, if you wish to buy them separately, you can choose to proceed with any reliable seed bank which has marijuana seeds. Seed banks are trusted places where breeders are hired to hand-pick the best quality seeds which are produced by crossing plants of different strains so that the stoners/growers get a unique experience. You can find a number of seed banks online as well as some physical stores where you can simply walk in and purchase the seeds that you need.
