Chelated Micronutrient Mix vs Drip Hydro 5 lb Micronutrient Fertilizer

Both are water-soluble trace-element blends for soilless and hydroponic growing, and the choice comes down to size and iron strength. The Drip Hydro 5 lb Powder D is the stronger, larger tub: higher iron, zinc, copper and molybdenum percentages and five times the quantity, so it suits bigger reservoirs and fewer refills. The Custom Hydro 1 lb mix is a repack of Plant-Prod's chelated blend with a published mixing rate and a small resealable jar, which fits small systems and custom recipes. Owners of the 1 lb jar describe it as a good size that lasts, and both are simple dry powders with no moving parts to fail.

• Choose the Custom Hydro 1 lb mix if you run a small or custom nutrient program and want a documented general rate with a jar that stores easily.
• Choose the Drip Hydro 5 lb Powder D if you mix larger volumes and want a stronger iron and zinc blend in one tub.
