PAR+

INCREASES EFFICIENCY of PHOTOSYNTHESIS FOR HIGH QUALITY INDOOR PLANTS

How PAR+ Works

PAR+ is made from a compound that is at the start of the metabolic reaction chain that produces both chlorophyll and antioxidants. Using PAR+ results on plants results in greener, stronger foliage with enhanced resilience to oxidative stress caused by the harsh environment (for indoor plants) found in most homes

Proven through Research at the World Renowned University of Nottingham, Sutton Bonington plant research centre.

WHY CHOOSE PAR+?

Enhances Chlorophyll Production

Drives more energy capture for denser,greener turf

Improves Stress Tolerance

Supports turf during intense sunlight, shade, heat, cold, drought and salinity pressures.c

Boosts Energy Flow

Increases metabolic activity and nutrient uptake

Proven At a UK University 

PhD level studies verify the effects of PAR+ on turfgrass surfaces

The above chart shows the effects of PAR+ on the Electron Transfer Rate (ETR), the speed of photosynthesis. PAR+ increases photosynthesis at every light level.

How to use PAR+

PAR+ is supplied as:

  • a liquid formulation that also contains micronutrients that help to promote photosynthesis and enhance PAR+

  • as a high purity white powder, used to make a liquid concentrate, which is further diluted in water before applying to plants.

APPLICATION GUIDELINES

Powder - dilute the powder into 1L of water to make a concentrated solution, then follow the guidleines below.

Liquid - follow the guidelines below if you have bought the liquid version

Stress Level                 Dilution          Frequency

 

Before stress occurs       2-4ml per         Spray on foliage every 

                                         litre water         2-3 weeks

Moderate stress              4-6ml per        Spray on foliage every

                                         litre water        3-4 weeks                                               

Severe stress                   6-8ml per        Spray on foliage every

                                         litre water        4-6 weeks

The above dilution and applications rates are a guide only. Users will need to trial and find the 'sweetspot' for their plants in the growing conditions provided.

Considerations for Optimizing PAR+ Application​

  • Application Frequency: Lower concentrations (2-4ml per litre water) can be applied more frequently, while higher concentrations (6-8ml per litre) should be used less often to prevent over-stimulation.

  • Environmental Factors: In warmer environments or during active growth phases, slightly higher concentrations (4-6ml per litre) may be needed, while cooler climates may benefit from lower rates (2-4ml per litre water).

  • Plant Species: Some plant species may have different tolerances to PAR+ due to differences in growth rates and stress tolerance.
