What is purpinator?

Purpinator’s all natural formulation is designed to provide plants with increased production of flavonoids like anthocyanins, which improve the colouration of plants, delivering deep, rich hues of purple in capable cultivars without modifying the growing environment.

Much like its alternative, Terpinator , Purpinator can be used with any nutrient line and will provide the building blocks for terpenoids; improving aromas, flavour, stronger colouration and a more varied mix of essential oils. Unlock the true genetic potential of your plants and see, smell, and feel the difference with Purpinator from Rhizoflora.

How does it work?

Typically, blue and red pigments in plants are influenced by anthocyanins such as cyanidin. Anthocyanins are a type of plant colour pigment that belong to the larger group of compounds known as flavonoids. The colour of an anthocyanin pigment is generally linked to the cell sap pH; the pigment cyanidin is blue in a high pH solution, violet in neutral solution, and red in more acidic conditions.

In combination with a blue light range of 400-500nm, also known as the action spectra for pigment production, Purpinator increases the production of flavonoids while maintaining a neutral cell sap pH, resulting in the expression of more “purple” in capable cultivars.

How to use Purpinator

Purpinator can be used during both the vegetative and reproductive phases of plant growth, up to and including fruit set.

During vegetation, add Purpinator at 2-5ml per 3.8 Litres of water.

During flowering phases, add 6-15ml per 3.8 Litres of water.

For superior fruit set add 20-30mls per 3.8 Litres during the last 2-3 weeks of growth before harvest.
