There are many ways to increase THC levels in marijuana.

One method involves using full-spectrum LED lights. Another involves feeding them the right amount of nutrients in a given growth stage. You can also try stressing the plant into producing more hairs.

However, there’s more to the potency of marijuana than just THC.

There’s been a handful of misconceptions that the strongest weed strains have high THC content, and while that statement isn’t wrong, it’s not entirely true either.

Higher THC content doesn’t necessarily mean you’ll get a stronger high from it, according to a 2020 study. This proven fact has only served to strengthen a theory that many cannabis connoisseurs have peddled from one enthusiast to another – the ‘entourage effect’. 

The theory around it essentially states that the potency of the high you get from weed isn’t just from THC alone, but rather a slew of different compounds that play with it.

Chemicals such as terpenes and CBD, also have an effect on your mind and body like THC.

On that note, the strongest weed strains for you might just have a relaxing effect on others. This is because we don’t share the same endocannabinoid system. 

However, the following list is known well throughout the marijuana community as being the strongest strains of weed that any person would have the pleasure of trying for themselves.

How to Grow High THC Weed

Increasing the amount of THC in your buds requires a couple of things. First, you must grow cannabis from high-quality seeds with good genetics, which you can buy at ILGM.com.

You can find all of the above strains in our online store. 

Once you have your seeds planted and sprouted, you’ll need to provide them with plenty of light. In particular, a full-spectrum LED light that provides UVA and UVB light will get you the best result.

Using the intense ultraviolet light on your cannabis plants will induce them into increasing trichome production, and more trichomes mean more THC.

Additionally, once your plants are in their vegetation stage, it’s wise that you provide them with the right amount of nitrogen and phosphorus, which are the ideal nutrients for increased trichome development. 

By pre-flowering, you’ll need to focus on the amount of phosphorus more. It’s important to know that nutrients aren’t the lifeblood of your cannabis but rather a means to boost its growth.

You can potentially over-fertilize your plants which can lead to nutrient burn.

FAQ’s About Strongest Weed Strains To Grow

What is the entourage effect?

The entourage effect is a theory that proposes the idea that different compounds in cannabis synergize to alter and even heighten the overall high that it provides. This means you can consume high levels of THC without feeling any of the side effects. The perfect example of this is 1:1 THC CBD strains, which offer little to no side effects but have a host of therapeutic effects, which include a mellow body and mind high.

What is the strongest sativa weed?

The strongest sativa strains are often hybrids; however, there are a handful of potent sativa strains such as Durban Poison. If you’re looking for something more potent, though, then look no further than in Green Crack. It’s a potent sativa dominant hybrid that hits you with a strong feeling of euphoria and energy. You can find seeds for both at ILGM.com
