Solufeed Sodium Free TEC™ is a chelated micronutrient source for growers operating advanced hydroponics systems who mix their own NPK fertilizers and wish to minimize feed sodium levels.

Solufeed Sodium Free TEC™ can also replace traditional Solufeed TEC™ is all other applications such as general fertilizer enrichment, fertigation and foliar feeding.

Solufeed Sodium Free TEC™ can be used in the hydroponic production of tomato, cucumber and other salad crops. It is particularly valuable in modern reticulating systems where the build-up of sodium would be detrimental.


Solufeed Sodium Free TEC™ is manufactured to ISO 9001 quality standards using only top quality raw materials and all reactive metals are fully chelated by the ammonium or potassium salt of EDTA. This ensures:

  • The formulation is sodium free.
  • Free-flowing, dustless and highly soluble in water. Easy to use for making up stable stock tank solutions with no sediment.
  • Efficient delivery of micronutrients – up to 5 times more efficient than sulphate-based mixes.
  • Quick and simple to use - only one product to source, hold in stock and measure out.
  • Consistent reliable Solufeed quality and product support.
  • Fully compatible with other feed constituents - prevents sludging, sedimentation, “rusty roots” and blocked feed lines.
