Biomin Iron | 2.5gal - OMRI Listed

Correct Interveinal Chlorosis in New Growth, 2.5gal

Iron deficiency is one of the most common micronutrient problems growers run into, and it shows up first as interveinal chlorosis, yellowing between the veins of the newest leaves, because iron doesn't move well from older tissue to new growth once a plant is short on it. Biomin Iron supplies iron in a bioavailable, non-phytotoxic chelated form for soil or foliar application, giving growers a way to correct that shortfall directly in the new growth where it shows up first.

This 2.5-gallon size suits a regular indoor or greenhouse feeding schedule, and pairing it with a nitrogen fertilizer keeps a single application pass covering both nutrients.

Key Features & Benefits

• Bioavailable Chelated Iron — formulated for ready uptake through soil or foliar application.
• Non-Phytotoxic Formula — safe on the interveinal chlorotic new leaves iron deficiency affects.
• Soil or Foliar Use — reaches new growth directly when foliar-applied, where iron deficiency shows up first.
• OMRI Listed — certified for use in organic production.
• Compatible with Nitrogen Fertilizers — drops into an existing feeding schedule rather than requiring a separate pass.

Who Should Use Biomin Iron

Biomin Iron fits growers seeing interveinal yellowing on new leaves, a classic sign of iron deficiency, or who want to prevent that shortfall during a crop's critical or fast-growing stages when new growth demand for iron is highest.

About JH Biotech

JH Biotech develops the Biomin line of chelated micronutrients, including this iron formula, engineered for bioavailability and low phytotoxicity so interveinal chlorosis can be corrected through soil or foliar feeding without disrupting the rest of a fertility program.

Frequently Asked Questions

What deficiency does Biomin Iron correct?

It's formulated to prevent and correct iron deficiency, which typically appears as interveinal chlorosis, yellowing between the veins, on the newest leaves first. Iron doesn't translocate well from older tissue, so new growth is where a shortfall shows up before anywhere else on the plant.

Why does iron deficiency show up on new leaves instead of old ones?

Because iron moves poorly from older tissue to new growth once a plant is short on it, the newest leaves are left without enough supply even while older leaves still look green. That's why interveinal chlorosis on new growth is the classic early sign to watch for.

Is Biomin Iron safe to apply directly to foliage?

Biomin Iron is formulated to be non-phytotoxic per label directions, whether applied as a soil drench or a foliar spray. Foliar application is often the faster route since it reaches new growth directly rather than waiting on root uptake.

How do I tank-mix Biomin Iron with nitrogen fertilizer?

Biomin Iron can be tank-mixed with nitrogen fertilizers, fitting into an existing feeding schedule instead of requiring a separate application. This makes it easy to fold an iron correction into a program that's already running.

Is this product OMRI Listed?

This 2.5-gallon Biomin Iron carries OMRI Listed status for organic production. That listing means certified organic operations can use it as part of a compliant iron-correction program.
