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 growers use to increase the number of trichomes. Enough to make your plant shine like a Christmas tree ...

Light on the production of trichomes

For best quality, the light should be very bright at the flowering stage. Cannabis plants grown in low light tend to grow less trichomes. In addition, it produces much less buds ... In addition a bud encrusted with trichomes is usually produced under strong 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 exposing cannabis buds to UV-B light for the last 2-3 weeks before harvest can increase trichome production and overall bud potency ( Bud). Although not yet proven, this may be in part because the 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 weaker blue / purple spectrum that humans cannot see. 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 against UV-B rays. Humans, once too exposed to the sun, are exposed to UV-B. Cancer results in extreme cases. In short, our skin protects us by becoming darker in response to sunlight. Instead of a tan 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 HD lights are generally only used in the vegetative stage, it may be helpful to expose the buds to UV-B light for the last 2 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 reptile lamps. Obviously, they will not be as powerful as a Metal Halide lamp ...

LED lights

Bien que la plupart des lampes LED ne produisent pas de lumière UV-B, certains producteurs croient que le spectre de la lumière unique de nombreuses LED soulignent certains aspect de la plante, dont les trichomes. En fait la plante produit plus de trichomes comme un moyen de défense contre certaines types de lumières LED. En général, la qualité de l' »agression » par LED, dépendra du prix que vous y mettiez…

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 to modify your environment for the last 2-3 weeks before harvest. What to remember is:

  • A humidity level of less than 30% - So a drop in humidity of the growing space of less than 30%, during the last 2-3 weeks before harvest. Make sure that your temperature remains below 26 ° C, so that your herbs do not dry on the spot and therefore lose power ...

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

  • Déshumidificateurs – Ils absorbent, ou enlèvent l’humidité tout en dégageant de la chaleur… Mais ceux de bonnes qualités, comme les « Air Conditoner », se débarrassent de l’humidité tout en refroidissant l’air.

Faire stresser vos plantes « positivement »

Étant donné que les plantes de cannabis peuvent produire des trichomes comme une réponse à certains types de stress, certains producteurs tentent de « choquer » leurs plantes, de la « bonne » façon  afin de déclencher cette réaction naturelle. La seule méthode éprouvée est d’abaisser le taux d’humidité et de contrôler l’environnement / l’éclairage comme indiqué ci-dessus. Mais il existe d’autres techniques non éprouvées qui peuvent ou peuvent ne pas fonctionner… La popularité de ces méthodes sont toutefois à mentionner.

Physical stress

Some techniques like supercropping (bending the stems without tearing) can increase the production of trichomes. However, this technique should be avoided for diseased or already damaged plants. It is therefore important to look at your plants closely ... Supercropping comes down to folding the plant in a way that twists them without tearing their structure. If done right, the yield will be even better at harvest.

Supercropping - Folding without breaking ...

Autre stress physique, certains producteurs réduisent les feuilles. Faites attention parce que si vous n’avez pas beaucoup de feuilles saines et vertes, cela peut décolorer vos buds… D’autres plongeront leurs plantes dans de l’eau glacée juste un peu avant la récolte. Ceci afin de « choquer » leurs racines, un genre de stress hydrique… Ces techniques ne sont pas prouvées, mais ce sont des stratégies sans beaucoup d’inconvénients si elle ne fonctionnent pas.

Increase of supplements

Some supplements sold in growshops actually claim to increase either the number of trichomes or the potency of your weed. The best and the worst will be found there ... But some products in the supplement world have time to prove themselves over and over again.

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

Choose a strain naturally rich in trichomes

If your strain does not have the genetics to produce a lot of trichomes, the chances are less that you will modify this… Although the advice given 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 they are basically poor and mediocre.

Ceci étant dit, certaines souches ne montrent pas beaucoup de trichomes, même si elles sont très puissantes. Comme par exemple, certaines Sativas et Hazes, ou la Sour Diesel. Donc si vous pensez que des « paillettes » sur votre plante est une chose importante, vous devez choisir la bonne souche. À ce stade, vous êtes armé de toutes les informations dont vous avez besoin pour développer vos propres incrustes de Noel : des bourgeons couverts de trichomes.
