      Add FASiLITOR to the water in your reservoir first before any other products. Failure to do so will result in a loss of FASiLITOR’s benefits. 

      As the flagship of the APTUS product lineup, FASiLITOR combines GMP certified manufacturing and industry leading concentration into a pure, fast acting, and exclusive formula. 

      FASiLITOR provides plant-available silica to and as needed across the vegetative, flowering, and fruiting phases of plant growth. Supplementing with plant available silica such as FASiLITOR helps to grow thicker cell walls within your plants. Benefits include promoting upright stature, solid stems & branches, and resistance to high temperature environments by reducing transpiration or loss of water due to evaporation.

      FASiLITOR’s formula also contains molybdenum, an essential component of enzymatic processes within the plant that convert nitrates into compounds used to manufacture amino acids, convert inorganic phosphorus into organic forms within the plant and is also crucial to bacteria that fix atmospheric nitrogen into your soil. 

      Industry leading concentration of just 0.5ml per gallon!

      Resistance against abiotic stress (environmental: temperature, wind, drought). 

      Reduces transpiration (loss of moisture from the leaves) by forming thick cell walls which are made primarily of silica and calcium. 

      Silicon Strengthens cell walls, increases resistance to drought, promotes upright stature of plant growth. 

      Boron Precursor to cell wall formation, translocator of plant energy (sugars), beneficial agent for flower and fruit formation. 

      Molybdenum Creator of crucial beneficial plant enzymes, synthesizer of organic phosphorus, and crucial to atmospheric nitrogen fixing bacteria in the soil. 

      Do not contaminate FASiLITOR with measuring instruments. Pour FASiLITOR into container of choice for measuring. 

      Always ensure you add FASiLITOR to your water before everything else including cal-mag supplements. 

      Combine with BLOOMBOOST for a great bloom phase foliar spray for the first 2-3 weeks of flower. 

      FASiLITOR is very effective as a foliar spray through veg and the first 2-3 weeks of flower. It’s also great at preventing powdery mildew.

      Fasilitor FAQs

      FASiLITOR is the most stable and concentrated plant-available silica supplement on the market. FASiLITOR has been shown in studies to modify plants’ mineral uptake behavior, increase the dry-weight of fruits and flowers, and prevent stress caused by environmental factors.

      There are 3 main types of silica products sold on the market today: Plant-available Silica (i.e. FASiLITOR), Common suits of silicates (Potassium Silicate & Calcium Silicate) and Silica Dioxide (sand/quartz).

      It’s important to understand that plants can only uptake and utilize silica once it has been broken down to a single molecule level (mono-silicic acid). Once silica has been broken down to a single molecule level the silica or silicic acid is then bioavailable and can be absorbed immediately by the plant either via the root or via the leaf.

      FASiLITOR is a patented formula of potassium silicate that’s easily broken down to a single molecule level (mono-silicic acid) and stabilized with Boron. This formula is 100% bioavailable meaning that once diluted into water it is available for immediate absorption by plants.

      Common Silicates (Potassium & Calcium Silicates) consist of a chain of molecules and are too large to be absorbed in their common form. Potassium or Calcium Silicate can be broken down to a single molecule level once amended into a soil by a process called weathering. This process takes 3 - 12 weeks and is virtually useless in an indoor or hydroponic cultivation environment with short crop cycles. It also makes the supplementation of additional silica inaccurate as you cannot accurately measure when the amended silica will be available to be utilized by the plant.

      Silica dioxide, also known as quartz or sand, is also not available for immediate uptake by plants and must first go through the process of weathering.

      Of all the silica products on the market, FASiLITOR is by far the most stable and the most beneficial. The longer plant-available silica can stay stable in a range where the plant can uptake it, the more effective and beneficial it is. The other factor to consider is FASiLITOR is stabilized using a small amount of boron which is the first element in the biochemical sequence of which plants operate.

      Always add FASiLITOR to your reservoir or foliar feed first and mix well before adding any other fertilizer or crop protection products.

      Add FASiLITOR at the rate of 0.5 ml per gallon during both the vegetative and flowering phases. In early flower (weeks 1, 2 and 3) you can safely double the dosage to 1 ml per gallon to minimize unwanted stretching.

      For foliar applications, add and mix 4 ml per 1 gallon. You can also add STARTBOOST, MASSBOOST and BLOOMBOOST to the same foliar spray mix.

      You do not need to add Fasilitor to our clean program to achieve great results, but adding Fasilitor will improve the overall health, vitality, quality and yield of any crop.

      Yes, FASiLITOR (like all APTUS products) can be used as a standalone product or paired with any other nutrient range.

      FASiLITOR will last a minimum of 7 days in a reservoir or hydroponic system. It’s recommended to use circulation pumps in place of air-stones to circulate/oxygenate the feed water as air-stones cause silicic acid to polymerise on the surface of the stone, creating the need for additional cleaning.

      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.
