Micro Green 2-0-3

Micro Green 2-0-3 is a water-soluble micronutrient fertilizer concentrate that delivers a complete trace-element profile for hydroponic, coco coir, and soilless growing. It supplies seven trace elements — iron, zinc, manganese, copper, boron, molybdenum, and calcium — in a single powder, replacing the need for multiple separate micronutrient supplements.

Iron, zinc, manganese, and copper are EDTA-chelated, which keeps these metals dissolved and available across the typical 5.5–6.5 reservoir pH range where unchelated forms tend to precipitate and become unavailable to roots. Boron and molybdenum are supplied in mineral form, which is naturally stable across that range. Micronutrient demand stays relatively constant through the growth cycle, so Micro Green is dosed at a steady rate from early growth through flowering, making it a straightforward addition to a recirculating reservoir, drip system, or coco feed.

Mix into a stock solution and store it in a dark container, since light can degrade the chelates over time. Add it to reservoir water rather than combining concentrates directly, and do not exceed recommended rates — copper and zinc can reach phytotoxic levels if overdosed.

CDFA registered and independently lab tested for heavy metals, with results consistently well below required limits.
