Your plants do all the work, at my job we use a product. at home i do not. 1 i cant get affodable testing in my state. 2 good terps are basically a outcome of plant health and if you opened all the right doors when needed so that the finished product has highest concentration of terpinoids... kinda a BS answer ...
i like to feed a shit ton of sulfur or even burn sulphur and have noticed a dramatic increase in smell/flavor. Sulfur aids in creation of enzymes and amino acids as well as creation of chlorophyll...
which in turn affects terp profile...its all relative, healthy plant and root zone and optimal enviroment... gonna have a good terp profile.
