Researchers from King Mongkutโs Institute of Technology Ladkrabang (Bangkok) and Thailandโs Institute of Scientific and Technological Research conducted a rigorous greenhouse trial on Cannabis sativa and found that a single preharvest foliar spray of salicylic acid (SA) at the right concentration and timing could significantly elevate THCA, delta-9-THC, total THC, antioxidant activity, chlorophyll levels, and phenolic compounds โ all in one shot.
