Aptus FaSilitor: Mono-Silicic Acid Plant Strengthener for Hydroponics and Soil
Aptus FaSilitor is a plant strengthener built around mono-silicic acid, which is the most bioavailable form of silica a plant can absorb. Traditional potassium silicate supplements require the plant to break the silicate down before uptake, and a lot of that input ends up precipitated in the reservoir. Mono-silicic acid skips that step — it's already in the form roots and leaves can use. That's why FaSilitor runs at a much lower dose than potassium silicate products and still drives stronger cell wall formation, thicker cuticles, and a visible improvement in structural rigidity. The 20-liter jug is the commercial size for facilities using FaSilitor as a regular part of the feed program.
Foliar and Root Drench Application Across Every Growth Stage
FaSilitor applies as either a foliar spray or a root drench. Foliar gets fast uptake through the stomata and is useful when you want a quick push on stressed plants or ahead of a heat event. Root drench builds reinforcement into new growth from the bottom up and works better as the baseline program through veg and bloom. The product plays well with other Aptus inputs like Regulator and Mycor Mix, and it's compatible with most base nutrient lines. At the 20-liter size, FaSilitor fits commercial rooms running foliar rotations and fertigation systems where a silica component is part of the core feed, not an occasional additive.
Key Features
- Mono-Silicic Acid Form: Most bioavailable silica source — already in the form roots and leaves can absorb directly without conversion.
- Lower Dose Than Silicates: More efficient uptake means smaller volumes do the work of much larger doses of potassium silicate products.
- Foliar and Root Drench: Dual-application flexibility lets you push fast response through foliar or build baseline structure through root feed.
- Cell Wall and Cuticle Strengthener: Builds thicker cell walls and cuticles for better structural support and resistance to pests and pathogens.
- 20-Liter Commercial Size: Production-scale volume for facilities running FaSilitor as a core part of the weekly feed program.
