      APTUS BLOOMBOOST is an additive used throughout the entirety of the fruiting and flowering periods of a plants lifespan. BLOOMBOOST contains a blend of plant available elements including potassium, sulfur, and boron that work together to increase fruit/flower size, fiber mass and quality. APTUS has designed this product to provide these three elements in precise amounts at desired times during the plants’ reproductive cycles to maximize harvests. 

      BLOOMBOOST is an excellent all-in-one health additive for your plants during their reproductive phase of growth. Using BLOOMBOOST throughout the fruiting and flowering phases of growth allows for increased flower setting, larger harvests, and heightened aroma in some species of plants.

      Potassium provided by BLOOMBOOST works to form healthy, fibrous fruits and flowers. 

      Sulfur is a crucial component in the formation of proteins, certain plant hormones, and aids in the formation of certain oils and volatile compounds. The supplemental sulfur works to bring out the aromatic characteristics of your plants early to develop even higher by harvest time. 

      The last element in BLOOMBOOST, boron works to preserve the integrity of various membranes within the plant which allows for continued structural integrity as your plants mature.

      One product contains multiple minerals beneficial for fruit & flower development with a low dilution ratio. 

      Contains elements crucial to the formation of certain oils and volatile compounds within plants. 

      Assists in the development of a healthy reproductive system within the plant. This includes healthy flower setting as well as pollen and seed formation for breeders.

      Boron Agent allows healthy cell wall synthesis and cell division.

      Sulfur Component of essential amino acids, aromatic characteristic promotant. 

      Potassium Thickener of fruit and flower structures.

      BLOOMBOOST may be used at a higher dilution ratio (up to 2ml per gallon) for an increased result in quality.

      Professional cultivators running the CLEAN Program often add BLOOMBOOST as a once per week feed to stimulate flower growth and oil production.

      Bloomboost FAQs

      No. Bloomboost is actually the complement to PK boosters. Bloomboost may be added to nearly any flowering program to provide required sulfur, boron and potassium that enhances flower quality.

      Yes, foliar spraying with Bloomboost for the first two weeks of flower is highly beneficial for initial flower set and development. We recommend adding Fasilitor to Bloomboost for the best results in a foliar mixture for the first two weeks of flower.

      You can use BLOOMBOOST in a recirculating system but keep in mind that BLOOMBOOST will form a biofilm which increases the need for cleaning. Most APTUS growers running recirculating hydroponic systems will add BLOOMBOOST to their reservoir 1 - 2 days prior to replacing the feed water which eliminates the build-up of biofilm and additional cleaning. Alternatively, you may consider running our CLEAN Program.

      Note: If you’re growing in a Deep Water Culture System DO NOT add BLOOMBOOST to the system. For DWC growers wanting to utilize BLOOMBOOST, it’s recommended as a foliar spray only for the first two weeks of flower.

      You can, depending on substrate and cultivation method. If you’re growing in rockwool it’s not recommended. Similarly if your grow is operating with a fertigation system, it’s not recommended to use BLOOMBOOST for more than one (1) feed per week.

      While most commercial cultivators want the benefits of using products like BLOOMBOOST or STARTBOOST, their main concern is keeping their fertigation system clean and free of biofilm. For these customers we recommend using BLOOMBOOST or STARTBOOST for one (1) feed per week only. This provides the plant with the additional stimulation desired, while ensuring the system remains clean and free of contaminants. You can use bio-stimulants in fertigation systems so long as it’s only once or twice per week. This practice will prevent the build-up of biofilm.

      Absolutely! BLOOMBOOST is an excellent supplement for all species of plants, especially flowering and fruiting plants.

      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.
