Why customers choose Cera Garden

Balanced nutrition for all plants

VIVOSUN Cal+Mag+Iron (2-0-0) is a concentrated liquid nutrient designed to support growth across soil, soilless media, and hydroponic systems. It delivers calcium, magnesium, iron, and nitrogen in a highly soluble form, making feeding through irrigation easy and consistent. While not a cure-all, many growers use this blend during active growth and when leaves show signs of nutrient stress, helping to maintain steady vigor and vibrant foliage.

Why this matters for your garden

  • Prevent & Correct Deficiencies: provides essential elements to help prevent common issues such as blossom end rot, interveinal chlorosis, stunted growth, leaf curling or cupping, and leaf brittleness.
  • Premium ingredients support growth: calcium, magnesium, iron, and nitrogen help drive photosynthesis and steady vegetative and fruit development.
  • Universal compatibility: 100% water-soluble and suitable for hydroponics, aeroponics, coco coir, DWC, soil, and other media; especially helpful in coco coir and RO water setups.
  • Compatible with other nutrients: works well with existing nutrient systems and can enhance overall nutrient uptake and efficiency.
  • Easy to use across growth stages: versatile enough to be used as a standalone additive or blended with other products; adjust dosage to fit your setup and plant response.

How to use and optimize

  • Start with a conservative dose and observe plant response before increasing application.
  • Mix thoroughly into your irrigation schedule and apply during regular feeding cycles.
  • Use throughout growth, flowering, and fruiting as needed to maintain steady nutrient availability.
  • Safe for indoor and outdoor use across a wide range of media and systems.

Designed to support healthy growth without promising guaranteed outcomes, this additive offers a practical option for growers seeking flexible, media-agnostic nutrition to supplement essential elements where needed.
