http://www.commonlink.com/~olsen/HEMP/IHA/iha01201.html Some studies at this link above suggest that resin production and canabanoid production is dramatically increased with less humidity and a higher THC to CBD ratio also results. The suggestion is that resin (the same waxy substance found on cacti) increases due to the plant trying to protect itself from losing water just as the cacti. Does anyone maintain humidity in their grow rooms? papaya
