Ultra Gro sPeKtrum is an enhanced blend of nitrogen, phosphorus, and potassium micronutrients. Ultra Gro sPeKtrum can be formulated with either Ecklonia (kelp) or Ascophyllum (seaweed) to fit your specific needs. Ultra Gro sPeKtrum also contains an enriched package of naturally occurring growth promoters, beneficial bacteria cultures with a carbon source, carbohydrates and essential chelated micronutrients (B, Mo, Cu, Fe, Zn, Mn, Si, Co) that significantly enhance crop yields, plant quality, vigor and resistance to environmental stress and pests. Designed for foliar application or soil application, it supplies vital nutrients at or near the time they are needed most.


Ultra Gro sPeKtrum is a low-salt liquid fertilizer ideally formulated for ease of nutrient uptake.


  • Low Salt Index that ensures plant safety
  • 100% Ortho-phosphate availability for the manufacturing of sugars
  • High I Potassium for the transport of sugars and stomata regulation.
  • Near neutral pH
  • Fast foliar uptake (immediate availability to the plant)
  • Fish Hydrolysate to feed soil microbes, making nutrients available
  • Humic and Fulvic acid — complexes nutrients and aid in uptake.
  • Beneficial Bacteria cultures with a carbon source
  • A true solution, not just particles suspended in a liquid
  • Use as a foliar application or mixed with other macronutrients and micronutrients and soil applied.
  • Tank-mix compatible with commonly used pesticides and fertilizers.
  • Apply prior to or immediately after nutrient deficiency symptoms occur to prevent further yield loss. In severe nutrient deficient crops, a second application should be made two weeks after initial application.
  • See the label for more information about specific crops, rates, and timing


Will increase the brix and solids in fruit prior to harvest.  Increases plants resistance to water stress, light frost, disease, and insect attacks.  Use soil and tissue test for selecting treatments to best manage nutrient levels within your crop.
