If you haven’t read it yet, you can find out more about the most potent THC strains in our previous post. — These are the Top 5 Strongest Strains of Cannabis
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.
Read on if you want to learn the tips and tricks for increasing THC.
Achieving high levels of THC isn’t a matter of luck or just choosing the right strain.. There are in fact things you can do before, during and after the grow that encourage THC production in your plants.
UV light is usually supplemented by the last two weeks of the flowering stage, as a final boost. It’s important to use safety measures when using UV light, such as safety goggles and long sleeved clothes.
Curious about the levels of THC in your bud? The HiGrade kit (Scope & Mobile App) lets you analyze your strain effortlessly.
Decreasing humidity levels in the grow room during flowering is essentially a way to make your plants a little bit thirsty. This goes by the philosophy that stress can induce progress. Stressing the plant in the way of making it thirsty can encourage the defensive response.
Girl Scout Cookies for example, is one of the most popular US strains with a high THC level, measuring in at around 28%.
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 for.
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…
However, there are several additional types of flushes that many growers believe will increase THC levels. Most of these are done in addition to regular flushing, just before harvest. Unfortunately, there aren’t many (if any) tests determining which one of these work, but there are many experienced growers who swear by these methods!
This cola has several weeks to go before it reaches its highest THC levels – harvesting now will reduce both your yields and your potency!
The sinsemilla bud that started flooding the market was much higher potency than the seedy, low-quality bud that had been available before. This led to the term sinsemilla being used to describe very high quality and potent cannabis. There’s no doubt that most growers prefer buds without seeds, but the term sinsemilla has led to the idea that cannabis buds without seeds were inherently more potent than seedy bud.
Allow Plant to Remain in Vegetative Stage For 8+ Weeks
I’ve heard this one from different growers over the years, but for now, the jury is still out. The idea is that a cannabis plant needs to remain in the vegetative stage for at least 8 weeks before being switched to the flowering stage in order to reach its maximum THC levels when it starts budding.
These are some of the common ways growers try to increase the THC levels of their cannabis. These techniques and methods are considered “unknowns” because there hasn’t been a whole lot of scientific testing to see what works and what doesn’t work as far as increasing THC.
My idea for a test (hopefully someday I’ll get to do this when I get more room to grow!)
There are a few growing techniques known to increase the THC of buds, as well as several "unknowns" which may also have a big effect on potency. Learn what you need to do to get the results you want!
