Ultrasol® Development

Ultrasol® Development is a formula which has been developed for the cell division phase, when the type and number of plant organs are defined and are being developed. This formula is ideal for cut flowers (such as for example roses) thanks to its 3:1:3 NPK ratio combined with extra magnessium.

  • Superior formula in terms of nutrition, highly concentrated, 100% soluble and ready to use.
  • Well-balanced supply of nitrate nitrogen and ammoniacal nitrogen.
  • Phosphorous present as highly mobile phosphorous.
  • Virtually chloride-free potassium source and 100% soluble.
  • Directly acidifies the nutrient solution and thus lowers the use of acids in neutral waters.
  • Does not crystallize and does not produce salt deposits in drippers and irrigation systems.
  • Comes with a full package of micro - nutrients.
