MicroCal liquid calcium carbonate is a heat, sun and light diffusion product that works through a process called double refraction.
This essentially divides the light rays as they intercept the crystals and reduces their energy.
Incoming light also hits the crystals. The size of the crystals matches the incoming wavelength and results in a 'sparkler effect' where the light is dispersed in multiple directions.
Both light division and the sparkler effect reduce solar energy absorption by the plant, resulting in lower temperature.
MicroCal
MicroCal is a liquid calcium carbonate making it easy to mix, it causes no mite flair and is easy to remove from fruit.
MicroCal has good rainfast and wear resistance and needs minimal applications.
