      FINALEBOOST is a concentrated finishing agent high in potassium and sulfur. Used by many cultivators around the world to increase the overall size, weight, density, aroma, and quality of their flowers, this phosphorus free formula is extremely bioavailable making it the perfect shaping tool for small and large scale cultivators.

      The dosage strength and application duration can be easily customized to match the characteristics and overall flowering duration of each unique strain.

      Using a phosphorus free potassium booster allows you to individually supplement the macro-element (K) to suit the preferences and metabolism of your plant genetics. 

      FINALEBOOST can be used as a standalone potassium booster at any stage of growth. 

      Stimulates fruit and bud maturation leaving a firmer end product. 

      Improves crop quality by increasing production of sugars and amino acids. 

      Minimizes mineral antagonism and lockout of potassium with other nutrients during the later part of flowering. 

      Powerful stimulating effect on the blooming and finishing process. 

      100% water soluble and leaves no residue behind. 

      Potassium Regulator of plant perspiration, fibrous mass enhancer, enzyme activator.

      Sulfur Component of essential amino acids, aromatic characteristic promotant in some plant species. 

      Using a phosphorus free potassium booster that contains a large amount of sulfur is highly beneficial for maturation in the final weeks of flower. 

      FINALEBOOST can be used as an additive to pre-load substrates such as perlite to prevent potassium deficiencies after transplant.

      Finaleboost FAQs

      FINALEBOOST matures and densifies flowers by increasing the production of essential oils, sugars and amino acids which leads to an increase in dry weight.

      Phosphorus (PEAKBOOST) is needed in higher amounts for the first half of the flowering phase to shoot and set flowers, whereas Potassium (FINALEBOOST) is needed in higher amounts for the last half of the flowering phase to mature, densify and ripen flowers. Separating the two elements provides the grower with more control for pheno-specific feeding and increases the availability of calcium, magnesium, nitrogen, zinc, iron, and copper throughout the flowering phase.

      FINALEBOOST, although highly available to the plant, is not a certified organic product. It is, however, clean running, stable, and able to stay in solution for several days without degradation.

      No, running FINALEBOOST for the last 3 - 4 weeks of any regime will increase the quality, weight and bag appeal of the finished flowers.

      If you ask any of the APTUS team we will always tell you yes because it is simply not needed. Although we have many customers that run FINALEBOOST for the last 3-4 weeks of their flower cycle in addition to their current regime and report fantastic results.

      Feed Programs


      This program is the easiest, most concentrated, low cost program on the market. The pH stability is so reliable you can mix and set your reservoir on a given day and it will read exactly the same (+- 0.05) seven days later with no adjustment in between.


      This program is the absolute gold standard of quality, flavour, oil production and shelf life. This is the program for the grower looking to produce the absolute best flower they can or any extraction artist looking to increase the quality, colour and yield of their extracts.


      Access to the OG programs that include Soil PRO and Soil BASIC, as well as the Extreme Program.
