Fertigation Fertilizers

Fertilizers used for fertigation and hydroponics must be completely water soluble and high purity — low in sodium, chloride, and heavy metals, with only plant-essential elements. Custom Hydro stocks the purest, most concentrated water-soluble fertilizer materials available, sourced exclusively from the most reputable suppliers in the world.

All heavy metals analyses are posted online at the CDFA Fertilizer Database. The labels are true and accurate — you can trust that what you’re applying to your plants is exactly what you intended.
