Cannabis strains have exponentially increased in number over the last few decades. In fact, thanks to innovative work within the industry, there are more being developed as we speak!
Though, if you’ve been consuming cannabis for some time, it’s likely that you’ve thought about cutting out the middleman and growing it yourself.
However, it can be tricky to know where to start, especially if you have limited space or live in an unpredictable or extreme environment.

Following, we’ve included a handy ‘need to know’ section so that you can make the most informed decision possible.
Northern Light is one of the most famous strains to emerge from the West Coast of the US in the 1970s and is thought to have been created using Indica genetics from Afghanistan.

White widow is a perfect choice for beginners and is among the most famous worldwide strains. White Widow was first developed in the Netherlands by crossing a resin-heavy Indica from South India and a Sativa landrace from Brazil.
Since then, it has been a staple in every dutch coffee shop. White Widow is 40% Sativa 60% Indica strain that uplifts consumers, inducing a euphoric, relaxed, happy, and social mood.
In fact, White Widow has quite the international reputation, as, without it, other incredible strains such as Blue Widow and White Russian would never have been created.
Its THC content is particularly high, at 22.5%, which also makes it popular amongst people who consume cannabis for medical purposes. The buds of this strain are colored white due to crystal resin, which acts as something of a warning for the intensity of its effects.

Afghan Kush has a high THC content, at roughly around 21%. Though, its effects can be felt far beyond its THC content, due to the plant’s ability to retain cannabinoids when extracted.
Its 6% CBD level and 1% CBN level also make this strain popular amongst people trying to alleviate depression, a lack of appetite, and traumatic stress.
It has an aroma that is a mix of tropical mango and earthy skunk. Its taste is very mild, so is a perfect choice for people with more sensitive pallets. Consumers often describe the taste of Afghan Kush as bland, with the smallest, most subtle hint of fruity sweetness.

What to know before you grow
Cannabis can be more high-maintenance than you’d expect. Before you pick a strain, you should consider how much space you have to grow your plants, if there are any lighting temperature constraints, and what kind of effects you’re desiring.
Check out the information below to ensure that you pick the perfect strain for you!
Indica vs. Sativa
In addition to their varying effects, with Indica strains making you feel more relaxed and Sativa strains making you feel more energized, Indica and Sativa plants tend to grow differently.
Indica strains tend to flower quicker, which means that you can collect your yield quicker. Indica strains also stay quite short and bushy and are therefore ideal for people with limited room indoors. They are also ideal for people living in cooler temperatures.
On the other hand, Sativa strains can be a little trickier to master. They tend to be taller and thinner than Indica varieties, and their yields are likely to be smaller than their Indica counterparts.
However, the effects of Sativa varieties are preferred by many people, and they would do very well in warmer temperatures.
With hybrid varieties, anything goes! It’s important to do your research thoroughly before purchasing a hybrid strain to ensure you’re able to care for the plant properly and as such, harvest a decent yield!
Feminized seeds vs. auto-flowering seeds
You will also want to think about whether you want to plant feminized seeds or auto-flower seeds. Both have unique properties that may be preferable depending on your growing experience.
With feminized seeds, you don’t have to worry about producing male plants, and you can expect to yield larger plants. The plants produced by feminized seeds can also be cloned, which makes them very popular amongst serious growers.
Auto-flowering seeds are often preferred by people who are new to growing cannabis. These plants bloom automatically, are smaller in size, are much easier to cultivate, and are quicker to harvest.
The lighting required is also very simple, as auto-flowering seeds are far more resistant to temperature fluctuations.
