Heres a blurb from RQS
Still didnt find the right thing i read
OTHER FACTORS YOU SHOULD CONSIDER
Humidity and temperature can also alter the trichome yield of a cannabis plant. With the right combination of these, you can simulate a more stressful environment where the plant believes it should increase trichome production. In the last 2-3 weeks of flowering (around the same time you should increase UV-B exposure), toggling humidity and temperature will be key. Try decreasing the relative humidity (RH) levels to around 30%. Some very resinous plants grow in the Middle East where the weather is quite dry and arid.
Although, this being the case, your temperature should not surpass 26°C (80°F). Having higher temperatures won’t affect your trichome yield, but it will ruin their potency. That’s something you definitely don’t want. To verify that temperatures are correct, give your buds a good smell. If you encounter a very pungent aroma, it might be an indication the temperature is too high. This will gradually degrade your trichomes, so be careful.
