If you want to know how to increase THC and other cannabinoids in your marijuana plants this article is for you. In the following article we will see how to maximize the potency of any cannabis variety, in the simplest and safest way.

🎯 Factors influencing cannabis potency

Cannabinoids levels in marijuana may vary depending on these factors:

  • Genetics
  • Environment
  • Cultivation
  • Conservation

1- Why is genetics important in the potency of marijuana?

Genetics is the most important thing, it is what will mark the full potential of a variety. This means that with a loose strain, such as the Duckfoot, you will never get an extreme potency, no matter how well you cultivate it and even if it has the perfect environmental conditions.

If its maximum THC potential is 7%, you cultivate it perfectly, it has the maximum of light, total darkness during the night period, perfect temperature and humidity… In other words, with all the ideal parameters, that variety will get a maximum of 7% THC.

On the other hand, with a potent genetics it is easy to get your joints to be potent, as long as you have a clear minimum care. For example, a White Gelatto, even if it suffers some heat, a little hydric stress, or some lack, it will give you a potent weed.

Whenever we think about getting the most potent marijuana comes to our mind to increase THC levels. This is a good thing because, as we have seen, THC is a determining factor, but it is not the only important thing. Within the cannabis terpenes it has been discovered that there is a very special one, since it acts on the CB2 receptor like another cannabinoid. Beta-Caryophyllene also has medicinal properties of its own, and when it works in synergy with high levels of THC and other cannabinoids it turns weed into a hard drug.

So we can say that the most determining factor when it comes to achieving the greatest potency of marijuana is genetics.

2- How much does the environment influence the level of cannabis potency?

The environmental conditions where a marijuana plant is cultivated can influence the amount of cannabinoids and terpenes that it obtains. Within these environmental factors the most important are the light and the temperature.

The trichomes that develop our favorite plants serve as a defense system against U-VB rays. It has been shown that the higher the levels of light intensity of different spectra, the greater the amount of resin. The best is sunlight, and indoors a combination of different luminaires

Temperature has a lot to do with the degradation of cannabinoids, especially terpenes and flavonoids. An ideal daytime temperature would be around 25 º C. indoors, being able to rise if administered a greater amount of CO2, another environmental factor.

3- Is the way of cultivating very important for the potency of the weed?

It’s really important, as we saw before, a perfectly finished plant is not the same as another plant of the same genetics badly cultivated. For example, when we read that PEV Seeds’ Gorilla Vip can exceed 25% THC it is true, but it does not mean that all those who cultivate it are going to get a marijuana with such high levels.

It even happens with clones of the same mother plant, you can give it to a colleague who is an expert in cannabis cultivation, the one who always brings out the best weed, so that he can grow it in his own way. Another cuttings from the same mother you give it to a friend who has just started the cultivation, so that he can grow it as he wants. It is very probable that if you do an analysis when both harvests, the buds of the expert colleague get higher levels of cannabinoids, don’t you believe me? Try it and you’ll tell me…

4- What does the way marijuana is conserved have to do with its potency?

It really matters a lot, so much so that a cannabis of high potency and delicious flavor can become a mediocre weed. Light, air and humidity can degrade the cannabinoids and terpenes of a crop, so it is very important to keep the buds properly after drying and curing.

The ideal is to keep the harvest in hermetic glass jars, in the dark, in an environment of low humidity. A good conservation is not going to turn a loose marijuana in a powerful grass, but it will get that the power and quality does not decrease, or at least it slows down to the maximum this process.

Another advantage of preserving perfectly cured buds is that they last much longer in optimal conditions, even reaching the next season without hardly changing. We have tried joints from old harvests, more than 5 years old, which were still very good. Obviously not as well as when he was 6 months old that we believe is the moment of maximum power of marijuana, but still very well.

👾 Tips and tricks to increase the potency of your cannabis

  1. Choose a variety with aTHC potential of more than 20%, if it is possible that it contains quite a lot of Beta-Caryophyllene and Limonene.
  2. Control to the maximum the parameters of the culture, at least these: maximum light, temperature around 25º C. diurnal and 18º C. nocturnal, humidity of more than 50% in growth and less than 50% in flowering.
  3. Use insecticides and natural preventive fungicides, to avoid that some type of plague stops the development of the plants.
  4. Observe the plants daily, if it can be with a magnifying glass or microscope, to correct possible deficiencies, blockages or plagues.
  5. Treat the flowers well, both during cultivation and after harvest. Sometimes I feel sorry to see some people grab the buds, or hit them ruthlessly. This is bad, not because they are also living beings, but because the cannabis resin are very sensitive glands that spoil when touched.
  6. Control parameters during drying, curing and subsequent conservation too, we have already seen how important it is to maintain cannabis right.

We have already seen the best way to improve the quality of our cannabis, and as you know the genetic potential is only an important part. So don’t worry, at Pevgrow we can offer you the best genetics on the market.

But, as you have been able to verify, the other part that is going to determine the total power of the marijuana ultimately is you, and on that hand we can also help you to obtain the greater success, so if you have any doubt you can ask us. And if you want others to get the best possible marijuana also the best thing you can do is to share this article, we thank you in advance.

7 Ways to Increase THC in Your Home Grown

Let’s be honest – one of the most important things marijuana growers are looking for is weed that knocks your hat off. For that, it has to be some pretty potent bud. Well, the good news is that as a grower, you have the power to induce higher THC content in your plants. Read this article to learn the tips and tricks for increasing THC.

  • 1. Pick a high THC strain
  • 2. Manipulate THC levels with light
  • 3. Decrease CO2 in the final stages of flowering
  • 4. Trick plants by lowering temperature
  • 5. Let your plants vegetate for longer than 8 weeks
  • 6. Decrease humidity levels
  • 7. The harvest and cure

Every marijuana grower has an invested interest in the final product’s THC levels. Whether you grow commercially or just for personal reasons, the THC level is as important as the colour, smell and yield. At the end of the day, if you grow deliciously smelling green weed but it doesn’t blow your mind when you smoke it, then what’s the point?

Achieving high levels of THC is not a matter of pot luck. There are things you can do before, during and after the grow that encourage THC production in your plants. This article is all about learning how to grow your weed to be as strong as possible. You’ll thank yourself for paying attention early, after your harvest is the dankest weed!

1. Pick a high THC strain

Of course, the right place to start is by choosing to grow a strain that has higher THC levels. The genetics of what you finally decide to grow is probably going to play the biggest role in your final THC levels. In fact, the strain you choose sets the bar as to how much THC you can expect – if you do everything right, of course.

Most first-time growers don’t achieve the full potential of THC that their plant is capable of. This is because simple errors can be made in the growing process that don’t allow for maximum THC expression. Having said that, if a strain has a general THC level of 20%, that’s probably as high as it will ever get – even if you’re the most badass grower out there.

All of this means that if you don’t choose a high-THC-strain to begin with, there’s almost nothing you can do that’s going to give you the levels you’re looking for. It all starts with the basic rule of growing. Pick the right seed.

Girl Scout Cookies is one of the most popular US strains with a high THC level, measuring in at around 28%. Bruce Banner is another high scorer when it comes to potency, at almost 29% THC. Things have started to get serious when it comes to THC levels in the world of cannabis genetics. It means that wherever you are in the world, there’s a cannabis seed that you can grow with the purpose of reaching THC potency.

2. Manipulate THC levels with light

One of the reasons that marijuana is called a “weed” is because it grows in pretty simple conditions. Even if you don’t give it a lot of light, it will still grow. So, the “grow hack” here is to give it a lot of light. That’s how we make it bigger, stronger and more powerful.

For the purpose of increasing THC, you can give your plants UV light. To understand what’s behind this, we have to do a very basic geography class. When we think about where cannabis grew the best and the strongest, it starts to become quite obvious why UV light helps.

The hightest THC sativas have always been discovered around the equator and the most potent indica strains have always come from mountains. What do these two places have in common? Of course, they are closer to the sun. These geographical locations have a greater exposure to ultra-violet light.

Trichomes, which are the anatomical part of cannabis containing the most THC, also happen to be a defence mechanism. A marijuana plant produces trichomes (the resinous part of the plant) to defend itself against strong UV rays as well as herbivores. So, by exposing your plant to UV light, you are encouraging the expression of this defence mechanism.

Growers can buy UV lighting and start exposing plants to them in the flowering stage. Remember – a marijuana plant doesn’t start developing trichomes until this growth stage, so there’s no point using UV lighting before the flowering stage.

3. Decrease CO2 in the final stages of flowering

A process that is familiar to many growers, not just of marijuana, is the ripening process. It is the same process as ripening fruit, where the resin glands of plants are stimulated to produce all of the sugary goodness that humans love. Nothing is different about the marijuana plant.

The ripening process takes place in the final stage of flowering, where your cannabis plant is producing its trichomes, terpenoids and flavonoids. Decreasing carbon dioxide at this stage encourages the production of ethylene. In fact, ethylene is the natural gas that is given off by ripening fruit. It is imperative to the ripening process.

When you decrease the CO2, the plant will give all of its remaining energy to the production of ethylene and ripening, and will produce more trichomes. This process should elevate the levels of THC for your final harvest.

4. Trick plants by lowering temperature

Tricking your plants into thinking it is winter is also another way to encourage high THC potency. By lowering the temperature (by 3-6°C) at the same time as you decrease carbon dioxide, you will mimic the autumn season, and of course, warn your plant of the upcoming frosty season. In doing so, your plants will rush to finish their flowering, thinking that winter is coming and freeze them to death.

While it is rushing to finish its flowering, most of its energy will be spent on resin production, which is where most of the cannabinoid and terpenoid profile exist. By decreasing the temperature, you might even allow your plants to have a stronger aroma than you initially expected.

5. Let your plants vegetate for longer than 8 weeks

Although this one isn’t a definite way to increase THC, some growers still use this method. In fact, letting plants vegetate for longer than 8 weeks is a popular way to increase the yield and make the plants grow bigger. There’s no certainty that this increases THC potency, but according to some growers, it’s possible.

The idea is that by leaving the plant in the vegetative state for longer, it is essentially bigger, which gives it the potential to produce more of everything. The potential to have higher THC might also depend on the fact that bigger plants require more intense lighting. And we’ve already talked about the effect of intense UV lighting on THC production. Well, this method is worth a try – even if you only get a bigger yield at the end of it all!

6. Decrease humidity levels

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 we talked about earlier, encourage trichome production.

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. This can contribute to higher THC levels in your cannabis plants.

7. The harvest and cure

Whether or not harvesting, drying and curing actually increases THC levels (this is up for debate), it’s important to the final product. Most marijuana enthusiasts have smoked weed that hasn’t been cured properly and is either too moist or too dry. For some reason, it doesn’t quite have the power that properly cured weed has. Nor does it have the aroma or the flavour.

We aren’t claiming that curing your weed raises the final level of THC, but if you don’t cure it properly, it might lose some of the THC content it originally had.

You can check out our article on how to properly harvest, dry and cure your weed, but the basics are simple. Let the moisture drain out of your weed slowly. Don’t rush it. Let your buds hang to dry and before they get too dry, let them chill out in some glass jars for a while. This ensures you the fluffiest, greenest and most potent buds.

Enjoy using these techniques, and of course enjoy the results of these techniques!
