Nutrifield Crystalic 1L

Crystalic is a refined late-flowering additive developed as part of the Nutrifield Signature Range, designed to maximise flower density, flavour, and final crop expression when it matters most.

As plants push through the back half of bloom, the mission changes. It’s no longer about building flowers; it’s about filling them, finishing them, and drawing out everything the plant has to offer. This is where most programs fall short. Crystalic is built specifically for this stage, using a precision blend of biostimulants alongside targeted potassium and sulphur to keep plants metabolically active and producing at their peak.

Potassium drives carbohydrate transport, moving the sugars produced during photosynthesis directly into developing flowers for increased density and size. Sulphur plays a central role in the biosynthesis of aromatic compounds, which are essential for the development of flavour compounds. Together, they form the nutritional backbone of serious late-flower performance.

Triacontanol is included as a precision metabolic activator, calibrated to enhance photosynthetic efficiency without tipping into overstimulation; sustaining energy production during peak flowering demand and supporting efficient biomass accumulation. Galactooligosaccharides provide a plant-available carbon source to keep root-zone activity strong during heavy flowering, maintaining consistent nutrient uptake when plants need it most. Aloe vera extract rounds out the biostimulant blend with natural bioactives that support nutrient absorption and overall plant vitality.

Produced using high-purity inputs, Crystalic delivers clean, reliable performance and stable pH behaviour, particularly important in intensive hydroponic and coco systems where consistency is everything. The result is improved carbohydrate partitioning into developing flowers, increased density, and enhanced flavour and aroma; achieved through metabolic efficiency rather than excessive nutrient loading.

Within the Nutrifield Signature Range, Crystalic completes the two-stage flowering strategy. PK Heavy builds the flowers. Crystalic finishes them.

Compatible with hydro, coco, and soil. Fully compatible with Nutrifield base nutrients.
