Increase the number of trichomes on the buds

To obtain a better crop in a marijuana crop, by increasing the production of trichomes on the buds

Trichomes make your buds powerful. That's why most producers are interested in making their cannabis plants produce as many trichomes as possible.
Here are the main strategies that growers use to increase the number of trichomes. What to make your plant shine like a Christmas tree ...

Light on the production of trichomes

For better quality, the light should be very bright at the flowering stage. Cannabis plants grown under low light tend to grow less trichomes. In addition, it produces much less buds ... Moreover a bud inlaid with trichomes is usually produced under bright and bright lights like HPS. But this is not the only factor that influences the production of trichomes.


Some growers (including some celebrities like Ed Rosenthal) believe that exposure of cannabis buds to UV-B light for 2-3 last weeks before harvest can increase trichome production and overall bud power ( Bud). Although not yet proven, this may be partly because trichomes are theoretically there to help protect the plant from UV-B rays.

Light influences the production of trichomes

UV-B is the name of a "color" of light in the lower blue / violet spectrum, humans can not see it. It is produced by the sun and causes damage to plants and humans.

The different types of UV

In fact, almost all organisms on earth have defenses to protect themselves from UV-B rays. Humans, once exposed to the sun, are exposed to UV-B. The result is cancer in extreme cases. In short, our skin protects us by becoming darker in response to sunlight. Instead of a tanning effect, the plants therefore produce trichomes. Theoretically cannabis could therefore protect us against UV-B rays ...

Metal halide (MH) lamps produce UV-B radiation just like the sun. Although MH lights are generally used only in the vegetative stage, it may be useful to expose the buds to UV-B light for 2 last weeks before harvest to increase trichome production. UVB light is also produced by incandescent bulbs. But they are not really bright enough to be used for this purpose.

Halide Metal Halide Lighting

Another option for UV-B light are the reptile lamps. Obviously, they will not be as powerful as a Metal Halide lamp ...

LED lights

Although most LED lamps do not produce UV-B light, some producers believe that the unique light spectrum of many LEDs highlight some aspect of the plant, including trichomes. In fact the plant produces more trichomes as a defense against certain types of LED lights. In general, the quality of the "aggression" by LED, will depend on the price that you put there ...

On the lights ..

In addition, in nature, trichomes protect the buds from many hazards, including insects. Thus, the plant produces more trichomes in response to certain types of stress.

Alternate temperature and humidity

Macro - Water drop on trichomes

The main thing to remember to increase your trichomes, is the modification of your environment for 2-3 last weeks before harvest. What to remember is:

  • Humidity level below 30% - So, a decrease in the humidity of the culture space below 30%, during 2-3 last weeks before harvest. Make sure your temperature stays below 26 ° C, so your herbs do not dry up and lose power ...

There are two ways to reduce humidity while maintaining the right temperature:

  • Déshumidificateurs - They absorb, or remove moisture while releasing heat ... But those of good qualities, like the "Air Conditoner", get rid of moisture while cooling the air.

Make your plants stress "positively"

Since cannabis plants can produce trichomes as a response to certain types of stress, some producers try to "shock" their plants in the "right" way to trigger this natural reaction. The only proven method is to lower the humidity and control the environment / lighting as above. But there are other unproven techniques that may or may not work ... The popularity of these methods are however worth mentioning.

Physical stress

Some techniques like supercropping (bending of the stems without tearing) can increase the production of trichomes. However this technique is strongly to avoid for diseased or already damaged plants. It is therefore important to look at your plants ... Supercropping is a folding of the plant in a way to twist them without tearing their structure. If done well, the yield will be better at harvest.

Supercropping - Fold without breaking ...

Other physical stress, some producers reduce the leaves. Be careful because if you do not have a lot of healthy green leaves, it can discolor your buds ... Others will plunge their plants in ice water just before the harvest. This is to "shock" their roots, a kind of water stress ... These techniques are not proven, but they are strategies without much inconvenience if they do not work.

Increase of supplements

Some supplements sold in growshops actually claim to increase either the number of trichomes or the power of your buds. There will be the best and the worst ... But some products in the world of supplements, have time to prove themselves and time again.

For example, Rhizoflora Terpinator is one of the most popular supplements in American growers. As the name says, it helps to increase the production of trichomes. It is used by farmers and commercials known to increase the number of trichomes and the production of terpenes. Other great supplements do too, refer to your favorite growshop. But it has been tried and tested by many professional producers in the world of cannabis.

Choose a strain naturally rich in trichomes

If your strain does not have the genetics to produce a lot of trichomes, chances are less for you to change that ... Although the tips in this article will help you maximize the genes in your plant ... But as a general rule, it is difficult to compensate for genetics if it is poor and mediocre.

That said, some strains do not show a lot of trichomes, even if they are very powerful. As for example, some Sativas and Hazes, or Sour Diesel. So if you think that "glitter" on your plant is an important thing, you must choose the right strain. At this point, you are armed with all the information you need to develop your own Christmas inlays: buds covered with trichomes.
