10 growing tips for weed with more THC

Grow tips for thicker buds, more yield, better weed and therefore more THC always do well.

Do you always buy the strongest weed in the coffee shop or are you dependent on weed with a lot of THC for pain control? That’s a good thing, because even if you grow your own weed, you can influence the THC content of your weed. 10 growing tips to increase the THC content of your harvest coming up.

Weed with a high THC content is not only weed that makes you stoned but also weed that tastes very good. A high THC percentage not only says something about the active ingredient THC but also goes hand in hand with a high terpene content and a generally better quality. In addition, weed with a high THC percentage is also simply worth more. Reason enough to grow the THC percentage as high as possible!

Cultivation tip #1: Choose the right genetics

Resin production (and thus THC production) is for the most part genetically determined. So if you would like to have a lot of THC on your buds, start with a strain that is known to produce a lot of THC. Some species can do that better than others. In general, white weed varieties and Indica’s are the better THC producers. If you work with cuttings this is also true, a mother plant that produces a lot of THC will also produce cuttings that produce a lot of THC, it’s that simple.

Growing tip #2: Keep them small

Marijuana plants depend on a good transport system for their development. A plant with long thin branches has a slower sap flow than a plant with short thick branches. Think of a motorway with 5 lanes and a country road. Where can more traffic drive? If you want your weed plant to produce a lot of THC, keep the internodes short and make sure the stems are nice and thick.

Growing tip #3: Time for growth

A cannabis plant that gives you a little more time to develop during the growth phase produces more THC than a plant that is put into bloom immediately after germination. So give your plant some time; when she is ready she will make the most delicious THC for you.

Growing tip #4: The right temperature

Weed plants produce THC among other things to protect themselves against dehydration. In the flowering phase, therefore, ensure a warm temperature during the day. Between 21 and 27 during the day is ideal, do not let it get more than a degree or 10 colder at night.

Growing tip #5: Shock therapy

Scare your plant in the last week of flowering by letting the nights get colder and colder and water it ice-cold. One week before the planned harvest, lower the temperature, especially at night. Every day a little more until the night temperature is below 10 degrees Celsius. To rinse the plant you can use cold water, some growers even give it ice water. The plant reacts to the cold temperature with the production of extra resin (and therefore THC). She feels that it’s almost over and tries to catch some pollen grains with the extra resin to fertilize it.

Growing tip #6: Light therapy

In parts of the world where the sun shines a lot of UVB light such as Afghanistan or Thailand, weed plants produce more resin and THC to protect themselves against this ultraviolet light. If you do it right an extra UVB lamp in the flowering phase can provide more THC, but beware because UVB light is not good for people. As long as the UVB lamp is on you should not enter your growing space.

Start in the 2nd or 3rd week of flowering with one hour of UVB light in the middle of the 12 hour light period. Increase the UVB light daily so that you end up with about 8 hours of UVB light per day.

Growing tip #7: The right diet

Of course, the right power supply also has an influence on THC production. If there is too much nitrogen (N) in the soil during the flowering phase, this can inhibit the ripening of the buds. Phosphorus (P) and potassium (K), on the other hand, promote the development of buds. Use a basic flowering nutrient during the flowering phase. An extra flowering booster can provide extra bud development.

Growing tip #8: Dry them out

At cultivation tip number 3 we already saw that the weed plant protects itself at high temperatures against dehydration with extra resin. This phenomenon can be further exploited by making the air in your flowering space as dry as possible. You can work with dehumidifiers, but if you don’t have any, try to cover it with pots and water reservoirs. Some people also place bowls of rice to draw the moisture out of the air.

Growing tip #9: Put them in the dark

Many growers have been putting their plants in the dark for the last two days. The thought is the same as the cold tip 5: the plant thinks, as it were, that it’s time to die and tries to fertilize itself with extra resin. In addition, terpenes and cannabinoids are produced at night, but the volatile terpenes are lost due to the warm growing lights. By harvesting after a dark period, you harvest at maximum.

Growing tip # 10: Pest your plants

By carefully teasing and stressing your plants at the end of the flowering phase, you can make them “think” they are dying. They will still want to reproduce and protect themselves and thus increase resin production. In nature, the plant also protects itself against herbivorous animals with the resin. Most animals did not like THC (unlike humans). Only do this in the last two weeks and do not do it too much, because weed plants can also become hermaphrodite again.
