Certain strains are just naturally more "trichome laden" or "frosty" than others. But lowering the humidity during flowering will frost your buds up, and MORE IMPORTANTLY, reduce the risk of mold forming on your buds. 60% is way high for flowering, 40%(or lower) would be better.so hold up now....my room is really consistent around 60%...i mean varies maybe 1-2% but pretty much sits right on 60. Would a lower humidity help get more trichomes?
