Let’s be honest  -  one of the most important things recreational cannabis growers look for is weed that knocks their socks off. For that to happen, it has to be a pretty potent bud. Well, the good news is that there are a few ways growers can induce higher levels of THC in their plants.

Read on if you want to learn the tips and tricks for increasing THC.

Cannabis growers have an invested interest in the THC level of their final product. Whether they grow commercially or for personal use, the THC level is as important as the color, smell and yield.

Achieving high levels of THC isn’t a matter of luck or just choosing the right strain; Actually, there are things you can do before, during and after the grow that encourage THC production in your plants.

Of course, the right place to start is by choosing a strain that already has high THC levels. The genetics of what you finally decide to grow is probably going to play the biggest role in your final THC levels ,  if you do everything right, of course.

That being said, most first-time growers don’t achieve the full potential of THC that their plant is capable of, due to simple errors that made during the growing process. For the sake of time, we’ll focus on quick takeaways growers should focus on to maximize the impact of their product.

Before we get started, it is important to understand that most of the THC and other cannabinoids in your buds, contained in its’ sparkly trichomes. HiGrade lets you easily test your bud’s THC levels by snapping a picture using your smartphone and using our mobile app to gauge its potency level.


Genetics is by far the most important aspect when growing. If your strain isn’t quality and hasn’t got the potential of providing high THC levels, you can try as many different techniques as you want — but they probably won’t work

The resin produced by cannabis can also be a protective film against dry weather conditions as well as very wet weather conditions. So, if your plants are feeling threatened by the “climate,” they might be compelled to produce more resinous material and can contribute to higher THC levels in your cannabis plants.

Once you have good seeds from a potent strain, your next job is to ensure the healthy growth of your plants. All of the tricks in the world won’t help you if your crop is sick or uncared.
