Down to Earth Solution Grade Gypsum | 5lb - OMRI Listed - (Case of 5)

OMRI Listed 325 Mesh Gypsum Powder for Reservoirs, Fertigation, and Drip Irrigation (5lb)

Down to Earth Solution Grade Gypsum is an OMRI Listed, high-performance 325 mesh powder providing calcium (Ca) and sulfur (S) — two essential plant nutrients. Designed for efficient delivery and immediate uptake, this fine powder can be used in reservoirs, fertigation systems, drip irrigation, or spray applications.

The 5lb size (Case of 5) is convenient for growers who apply solution grade gypsum through irrigation or fertigation systems regularly throughout the growing season, or who want a concentrated supply for targeted calcium and sulfur supplementation.

Key Features & Benefits

• OMRI Listed — Approved for certified organic production.
• Solution-Grade 325 Mesh Powder — Ground to 325 mesh for rapid dissolution and suspension in water for liquid delivery.
• Provides Calcium and Sulfur — Supplies two essential plant nutrients — calcium and sulfur — in a single application.
• Designed for Fertigation and Drip Irrigation — Formulated for use in reservoirs, fertigation systems, drip irrigation, and spray applications.
• Immediate Uptake — Fine particle size supports efficient delivery and rapid availability for plant uptake.

Who Should Use Down to Earth Solution Grade Gypsum

Solution Grade Gypsum suits growers who apply calcium and sulfur through liquid delivery systems including drip irrigation, fertigation, and reservoir-based growing systems. It is particularly valuable for those who need calcium and sulfur supplementation in a water-soluble form for ongoing delivery through irrigation without switching to granular soil amendments.

Calcium and Sulfur Through Liquid Delivery Systems

Gypsum (calcium sulfate) supplies calcium and sulfur — two secondary plant macronutrients. Calcium supports cell wall formation, normal cell division, and proper fruit development. Sulfur is required for enzyme activation, amino acid synthesis, and chlorophyll formation. Solution Grade Gypsum is ground to 325 mesh — a very fine particle size — enabling it to be suspended in water and delivered consistently through reservoirs, fertigation lines, and drip irrigation systems throughout the growing season.

Frequently Asked Questions

What makes Solution Grade Gypsum different from granular gypsum?

Solution Grade Gypsum is a 325 mesh ultra-fine powder designed for liquid delivery through reservoirs, fertigation systems, drip irrigation, and spray applications. Granular gypsum products are broadcast as soil amendments. The fine powder allows it to be suspended in water and delivered through irrigation lines for efficient calcium and sulfur delivery.

Is Down to Earth Solution Grade Gypsum OMRI Listed?

Yes. It is OMRI Listed and appropriate for certified organic production.

Can it be applied through drip irrigation?

Yes. It is designed for use in drip irrigation, fertigation systems, and reservoir applications. The 325 mesh particle size allows it to be suspended in water and delivered through irrigation lines.

What nutrients does Solution Grade Gypsum provide?

It provides calcium and sulfur — both essential secondary macronutrients. Calcium supports cell wall formation and fruit development. Sulfur supports enzyme activation and protein synthesis.

Can Solution Grade Gypsum be used as a foliar spray?

Yes. It can be applied as a spray application in addition to fertigation and drip irrigation uses. Follow current label directions for rates and dilution by application method.
