Hydric Stress
Another interesting study, published by the American Society for Horticultural Science, has shown that the application of drought can increase the amount of cannabinoids in cannabis plants. Although it does not indicate specifically about trichome production, the introduction of this technique can boost THC, which may be an indication for some extra resin growth (as a result of the stress).
Whether this works depends on the species of cannabis and its ability to handle drought. In the study, the plants in the test group were without water for 11 days after the start of week 7 in flowering (water potential 1.5MPa = drought stress threshold, plant wilting). After feeding again and finishing their cycles, yields showed a 50% increase in THC.
