How THC Levels in Cannabis Strains Have Evolved

Tetrahydrocannabinol aka THC

How THC Levels in Cannabis Strains Have Evolved. Marijuana’s potency is measured by THC percentage, and when it first began being tested for in the 1930s, the average THC percentage was around 4%.

In the past couple of decades, we have seen it rise to an all-time high of 10%, with certain strains such as White Widow and Silver Haze testing as having THC levels as high as 30%. Overall, the biggest increase in the average would have to be from 4.8% (tested in 2003) to 7.3% (tested in 2007).

Nowadays, there are a plethora of strains, both indica, and Sativa, that are putting the average THC potency to shame. Though the potency in some plants today is almost 5 times stronger than those 20 years ago, none of them have been cleared for proper testing.

Modern growing methods have also had a major effect on THC and CBD levels. Now that marijuana can be grown indoors in such expensive grow rooms (of which there are so many) and tended to as needed, their potency has been on a dramatic increase.

From the types of UV lighting to the complicated ventilation systems growers put together, there are a thousand ways to grow your plant exactly to your specifications and achieve high potencies.

One of, if not the, major factors in the potency equation is just good old genetics. If you have seeds from a very potent plant, such as Sour Diesel or AK-47, the odds of you producing your own potent strain are likewise higher. Grade A marijuana seeds can be purchased safely online or bought from a local source. And of course, high potencies also exist in abundance because many strains today are in fact cross breeds of two or more potent strains.

The last major factor in producing potent marijuana is the harvesting process. If your marijuana is harvested prematurely, you could, for instance, end up with a batch of Northern Lights that has a measly THC percentage of 0.8%. Letting the plant grow into full maturity is important.

Also, after the plants are cut and trimmed of their leaves, they must be cured and left out to dry. The method in which you do this could determine the amount of crystallization you get on your buds which could greatly affect the THC percentages.

In conclusion, if you take proper care of your plants and have seeds capable of producing top notch quality, you should be able to harvest a crop with high (or your desired) THC percentages.

  1. You have the damn thing backwards! Who taught you how to grow?? First of all, I use the fan leaves all the time to smoke. Sure, they are harsh, but if you have enough of them, you WILL get high. You won’t get blasted, but I have gotten a nice high from Tut plants, Blueberry, ak-kali, and even my AK-47 plants. And your measurements are off as well. You really think you will get high from a plant that produces .87% THC?? Listen, I grew up in the 1970’s, and pot was about 12 percent THC for good colombian. Panama red, the GOOD shit, was about 16 percent, maybe 18 percent, and THAT is why they called it “ONE HIT WONDER”!! And that is because we were use to pot that was only 10 to 12 percent THC. We also had tabs of THC that were about 50 percent pure, and crystal THC, MADE IN A LAB, that was anywhere from 50 to 75 percent pure! A small line would get you WASTED for hours! If you drop it in a glass of water, like I did, and drink it down, you would be TOTALLY FUCKED UP FOR TWELVE HOURS!! AND THAT IS NO LIE BECAUSE I DID IT! IT WAS BEING IN A BUBBLE! THE BEST DAMN HIGH I EVER GOT! Now, the average THC for good plants are 18 percent. I have had plants that were 21 percent or better, and had a TUTANKHAMEN plant that was 33 percent THC! My friend’s Diesel plant is at LEAST 24 percent THC! So I think you better do more research. You are out of touch with reality.

    1. The THC you were doing was actually PCP. I also grew up in the 70’s and I do know exactly what you’re talking about.
