Uncle John's Blend (UJB), is a Potassium mixture that is used primarily to enhance a plant's metabolic rate, especially for flowering plants during the blooming stage. Potassium is a major component in photosynthetic processes, including the production of ATP (plant sugars) and the transfer of those sugars throughout the plant tissue. UJB makes a very "clean" foliar spray that will not leave heavy built-up or residue on the plant tissue. UJB can also be used in conjunction with our 2 other additives for custom foliar applications.
UJB can be used throughout the entire growth cycle, but definitely is more critical in the flowering stages of a plant's life to maintain energy levels and maximize plant growth. A plant is essentially "dying" as it goes to fruit or seed, adding UJB helps to maintain the metabolic rate of plants that are in some cases not producing as much ATP towards the end of its blooming/fruiting stage.
