Sorry for the delayed reply, I actually have not used it in perticular but i believe it helps with your sugars and or carbs. Raising the overall resin content. I would say you would be fine using it with kool bloom, its just an additive anyways. In all honesty Ive found molasses to be one of the best sources for this same type of product and it works great, costs next to nothing! Good luck brotha, If you havent bought it yet then just go buy some blackstrap molasses and buy GRAVITY instead of SNOWSTORM. Gravity is from the same people and really denses up your buds. Its good stuff. Gravity in addition to molasses and a base nutrient you will do well
