I have had very little to no luck getting any of there carb products to increase bud/harvest size, but if you are using microbes in your soil or brewing teas then they can have a profound effect. But on the flavor and l-amino acid side of things, I have successfully flavored and/or enhanced natural flavors with such products, but I prefer matching the sweetener to the plant like Botanacare Sweet Citrus with Sour Diesel/OG or GH Flora Nectar Pineapple Rush with Pineapple Express. And I have also found if I REALLY want to force a flavor on a plant I dump 100-200ml of STRAIGHT sweetener directly onto the base of the plant/soil in the last few days of flushing so that the last thing and only thing the plant has to eat is some serious flavor.
