OK so.
Sugar is a source of carbon, the building block of all organic compounds.
Resin-producing plants need lots of carbon to produce resin containing cannabinoids, a class of aromatic compound (aromatic not simply meaning they are smelly, but that the molecules contain one or more carbon rings).
If Carbon is the limiting factor in how much resin a plant can produce (yes, I know it's strain dependent too, bear with me), how well does the addition of sugar actually work to optimize this process?
Are products such as Sweet effective? Are they more effective than watering with any of the 'grocery-store sugars'?
