Biomin Calcium | 2.5gal - OMRI Listed

Support Cell Strength During Rapid Fruit and Vegetative Growth, 2.5gal

Calcium moves through a plant slowly and only travels to where water is actively transpiring, so fast-growing tissue like new fruit or expanding leaf margins can run short even when the growing medium tests fine for calcium overall, showing up as blossom end rot or tip burn. Biomin Calcium supplies calcium in a bioavailable, non-phytotoxic chelated form for soil or foliar application, giving growers a way to reach that fast-growing tissue directly instead of waiting on root uptake alone.

This 2.5-gallon size fits a regular indoor or greenhouse feeding schedule, and since it may be applied together with nitrogen fertilizer, it drops into an existing program rather than requiring its own separate pass.

Key Features & Benefits

• Bioavailable Chelated Calcium — formulated for ready uptake through soil or foliar application.
• Non-Phytotoxic Formula — corrects calcium deficiency without burning foliage when applied per label directions.
• Soil or Foliar Use — reaches fast-growing tissue directly when foliar-applied.
• OMRI Listed — certified for use in organic production.
• Compatible with Nitrogen Fertilizer — layers into an existing feeding schedule instead of requiring a separate pass.

Who Should Use Biomin Calcium

Biomin Calcium fits growers seeing symptoms like blossom end rot or leaf tip burn, or who want to protect fast-growing fruit and foliage during critical or fast growing periods when calcium transport to new tissue is most likely to fall behind demand.

About JH Biotech

JH Biotech develops the Biomin line of chelated micronutrients, including this calcium formula, engineered for bioavailability and low phytotoxicity so fast-growing tissue can get direct correction through soil or foliar feeding without disrupting the rest of a fertility program.

Frequently Asked Questions

What deficiency does Biomin Calcium correct?

It's formulated to prevent and correct calcium-related micronutrient deficiencies, which often appear as blossom end rot on fruit or tip burn on leaf margins. Calcium moves slowly through a plant and concentrates wherever water is transpiring, so fast-growing tissue is the first to show a shortfall.

Why would I foliar-apply calcium instead of just feeding it through the roots?

Because calcium travels through a plant only as fast as water moves, root-applied calcium doesn't always reach fast-growing tissue like new fruit in time. A foliar application of Biomin Calcium delivers it more directly to that tissue.

Is Biomin Calcium safe to apply directly to foliage?

Yes, it's formulated to be non-phytotoxic when applied according to label directions. That's what makes foliar application practical without risking leaf burn.

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

It may be applied together with nitrogen fertilizer, so it fits into an existing feeding schedule instead of requiring a separate application. This makes it easier to add a calcium correction to a program that's already running.

Is this product OMRI Listed?

This 2.5-gallon Biomin Calcium is OMRI Listed for organic production. That certification lets certified organic growers include it in a compliant fertility program.
