Plant-Prod® Chelated Iron 11% DTPA 5lb

Plant-Prod® Chelated Iron 11% DTPA 5lb — Professional Iron Supplement

Plant-Prod® Chelated Iron 11% DTPA is a professional-grade water-soluble iron fertilizer providing 11% chelated iron in the highly stable DTPA (diethylenetriamine pentaacetic acid) chelate form. Iron is an essential micronutrient required for chlorophyll synthesis, enzyme function, and electron transport in plants. Iron deficiency — manifesting as interveinal chlorosis (yellowing between leaf veins on young growth) — is one of the most common micronutrient disorders in indoor growing environments, particularly in alkaline substrate and nutrient solution conditions.

DTPA chelation protects iron ions from precipitation and chemical inactivation across a broad pH range (approximately 4.0–7.5), ensuring that iron remains plant-available in both soil and hydroponic growing environments. The 5lb package size is well-suited for commercial indoor cultivation facilities and growers who need consistent iron supplementation at scale.

Key Features & Benefits

• 11% Chelated Iron — DTPA Form: High iron concentration in the DTPA chelate form provides excellent water solubility and broad pH stability. DTPA chelation is effective across a pH range of approximately 4.0–7.5, making it suitable for the widest range of growing conditions encountered in indoor cultivation environments.
• Rapid Iron Chlorosis Correction: Interveinal chlorosis caused by iron deficiency responds quickly to chelated iron applications. DTPA-chelated iron is immediately plant-available, providing rapid restoration of normal green coloration in affected plant tissue.
• Chlorophyll Synthesis Support: Iron is a critical cofactor in the enzymatic pathway for chlorophyll biosynthesis. Adequate iron levels ensure that plants can produce sufficient chlorophyll for efficient photosynthesis and healthy green tissue development throughout the growing cycle.
• Hydroponic & Soil Compatible: Dissolves completely and remains stable in hydroponic nutrient solutions. Also suitable for soil drench and foliar applications in soil and soilless growing environments where iron availability is compromised by high substrate pH.
• Commercial 5lb Format: The 5lb package provides a large supply of chelated iron for commercial growers and indoor cultivation facilities that require consistent micronutrient management across multiple growing cycles.

Who Should Use This

Plant-Prod® Chelated Iron 11% DTPA is ideal for commercial indoor growers, hydroponic facilities, and serious home cultivators who encounter recurring iron deficiency in their crops. It is particularly valuable in growing environments with elevated substrate or nutrient solution pH, where iron availability is naturally restricted. Growers building custom nutrient formulas from scratch will also appreciate having a reliable, high-purity chelated iron source in their nutrient mixing toolkit.

Compatibility

Fully soluble and compatible with most hydroponic nutrient programs. Add to the diluted nutrient solution rather than concentrated stock solutions to prevent potential precipitation reactions with concentrated phosphate or sulfate compounds. For soil applications, dissolve in water and apply as a drench. Foliar applications are also effective for rapid correction of acute deficiency symptoms. Store in a cool, dry location away from moisture to preserve chelate stability.

Frequently Asked Questions

What causes iron deficiency in indoor growing environments?

Iron deficiency most commonly occurs when substrate or nutrient solution pH rises above 7.0, causing iron to precipitate into insoluble forms that plant roots cannot absorb. It can also result from genuinely inadequate iron in the nutrient solution, or from antagonistic interactions with other elements like manganese or zinc at excessive concentrations.

What is the difference between DTPA and EDTA chelated iron?

Both DTPA and EDTA are synthetic chelating agents used to keep iron plant-available. DTPA chelation is stable and effective up to approximately pH 7.5, while EDTA chelation begins to break down above pH 6.5. For growing environments with higher pH, DTPA is the more reliable choice.

How do I recognize iron deficiency in my plants?

Iron deficiency appears as interveinal chlorosis on young leaves — the tissue between the leaf veins turns yellow or pale while the veins themselves remain green. Unlike magnesium deficiency, which appears on older leaves first, iron deficiency symptoms appear on the newest growth at the top of the plant.

Can I apply this as a foliar spray?

Yes. Chelated iron can be applied as a foliar spray for rapid correction of acute iron deficiency symptoms. Dissolve at the recommended rate in clean water, apply to leaf surfaces early in the day, and avoid application under intense light to prevent leaf burn.

Is 5lb an appropriate size for a small home growing environment?

The 5lb format is best suited for commercial operations or growers who manage multiple growing cycles per year and require consistent iron supplementation. Home growers with a single small growing environment may find a smaller quantity more practical unless iron deficiency is a persistent recurring issue.
