Some strategies to stress plants to increase trichome production:
Tips for taking good pictures of trichomes
Many other types of plants besides cannabis produce trichomes, including many aromatic herbs like mint and rosemary. These plants produce essential oils in their trichomes which are used to deter insects and protect the plants from other stressors, just like cannabis plants!
Metal halide grow lights produce UV-B light just like the sun! Although MH lights are generally only used in the vegetative stage like for these plants below, it may be helpful to expose buds to UV-B light for the last 2 weeks before harvest to increase trichome production.
Harvest when nearly all trichomes are white for the greatest mental effects
Although these do make trichomes appear bigger, the main problem with loupes/magnifiers is that they don’t magnify things quite big enough for some people. At least with my eyes, I have trouble seeing trichomes well enough to determine the color under a loupe. That being said, lots of growers use these without a problem!
In fact, nearly all organisms on earth have defenses to protect themselves from UV-B rays. Humans get sun-burned if exposed to too much UV-B and can even get cancer in extreme cases, so our skin protects us by becoming darker in response to sunlight. Instead of a tan, plants produce trichomes that can help protect against UV-B rays (though trichomes also have many other uses such as producing cannabinoids and terpenes/essential oils/smells).

- Supercropping – Bending/snapping plants in a way that stresses them without “breaking the skin” (if done right this can increase yields, too)
- Other Physical Stress – I’ve heard of growers cutting leaves and putting nails though stems the last day or two before harvest. The later option makes me sad 🙁
- Give 24-48 hours of darkness just before harvest – Be careful because if you don’t have a lot of green healthy leaves, this may discolor your buds.
- Water plants with ice water just before harvest – I’ve heard of some growers giving plants icy water just before harvest to try to shock their roots. Again, this is an unproven method…
