Don't bother, molasses has no scientific basis as actually benefitting your plant and is an outdated "old wives tale" that some hippie came up with 50 years ago, the logic being that a sugary solution will lead to a plant producing more "sugar" (trichomes). There is nothing in molasses that benefits your plant directly. There may be a small benefit for some types of of soil microbes, but fulvic acid or humic acids will provide ten times more benefit while actually having a positive effect and a real benefit that is scientifically proven, for your plants.
Hope this helps,.... Organoman.
