For example, let’s assume that your particular cannabis strain has a THC upper limit of 10%. This means that under optimum growing conditions, the highest potency level that can be achieved is 10%. No amount of growing techniques or tricks can make a plant exceed its genetic boundaries as far as potency is concerned.
Plant Care and Health
This means that the plant puts all its energy into producing resin and improving the cannabinoid content of its buds. More resin production translates to a bigger harvest and higher quality buds with potent THC levels.

Here are a few of the main reasons for boosting a crop’s THC content:
Hack 1 – Strain & Individual Plant Genetics
A strain’s genetics is the single most important aspect of weed cultivation. No matter what, if a strain is incapable of offering 20%+ THC, no amount of work will help you achieve it. Moreover, if you don’t grow the plant correctly, you’ll end up with far less THC. Right off the bat then, you need to pick a high-potency herb such as Girl Scout Cookies (25-28%). Other examples include:
Hack 2 – Harvesting
There are lots of different reasons why people want to increase the level of THC in their buds. Some do it for medical reasons, while others do it for the high.
If you are serious about increasing the THC levels in your cannabis, make sure to follow the top steps which are known to increase potency! Skipping any of those steps will reduce your potency for certain. Choosing the right strain, giving plenty of bright light, taking great care of your plants while they’re alive, and harvesting/drying/curing properly are the most important steps you can take to increase the THC levels of your buds!
My idea for a test (hopefully someday I’ll get to do this when I get more room to grow!)
Much of the THC and “potency” in your buds is contained in the sparkly trichomes
There are many supplements for growing cannabis, and each one has a different purpose. Some supplements are great, while others are just snake oil.
Your plant genetics set the “upper limit” of how much THC and other cannabinoids your plant will ever be able to produce. Although you can use grow methods to maximize the THC within that limit, you will never be able to overcome the limits set by your strain and plant genetics.
Highest Level of THC When…
Type of Grow Light & Spectrum – HPS, LED & LEC Grow Lights
Different types of grow light produce different spectrums (colors) of light. There are some growers that believe that growing cannabis under the unique light spectrums of LED grow lights or LEC grow lights may increase resin production and THC levels. Other growers swear that you need powerful HPS grow lights to produce the highest levels of THC.
