Milliliters per gallon of water

Before mixing, water should be at 5 - 7 pH and after all products are added the resulting pH should be within 5.6 - 6.3

Earlier in plant cycles, lower use rates can be used until plants become established. If plants are known cultivars that are salt tolerant and environmental conditions can match feeding rates then higher rates may be used. For example: ideal conditions (high CO2 – 1100-1700ppm; PAR > 1300) can warrant higher than specified use rates.

VPS Nutrients do not contain heavy metals, unnatural organic compounds or harmful additives, so a flush is not necessary. If your growing operation follows a perpetual harvest method, maintain feed rates until harvest. If VPS is used in inert media such as Coco Coir or Rockwool, periodic flushing is determined by continuous liquid feed concentration, environmental condition and evaporation, and other fertigation and environment factors. 

The Ventana Plant Science line was formulated as a complete solution with mineral nutrients and organic inputs included. There is nothing additional required to grow healthy plants.

Yes! The VPS Line was formulated as a complete hydroponic nutrient and will work in soilless, inert media, and soil plant production.

The Ventana Plant Science line has no known compatibility issues with any other products. If you choose to use other silicas than VPS Structure or Silicon, you must ensure it is added during mixing at the same stage as the VPS products, similarly with any other CalMag supplements and the Support. Any other non-mineral additives should be added at the end of mixing with pH balancing before feeding.
