Pulverized dolomitic limestone, #80 grit, 50 lb bag for growers seeking a finely milled mineral amendment for soil, potting mixes, and selected soilless media. This high-magnesium limestone provides calcium and magnesium while helping support pH management in acidic growing media.
The fine powder blends evenly through prepared media and is suitable for horticultural production, greenhouse crops, container gardens, and commercial soil-amendment programs. Apply according to crop requirements and confirm media pH with a reliable test before and after use.
Key Features & Grower Benefits
- Fine #80 grit texture: Pulverized mineral powder disperses more consistently than coarse limestone in properly mixed growing media.
- Calcium and magnesium source: Supplies two important secondary plant nutrients for balanced crop nutrition.
- Supports pH adjustment: Dolomitic limestone can help moderate acidic soil and soilless media when used at an appropriate rate.
- 50 lb commercial-size bag: Practical for greenhouse benches, propagation rooms, container production, and larger soil-blending projects.
- Easy to incorporate: Blend thoroughly into dry media before planting, following crop-specific recommendations and verified pH targets.
Recommended Applications
Use this pulverized limestone in indoor grow rooms, grow tents, greenhouse benches, nursery containers, raised beds, and commercial media-blending operations. It is especially useful for preparing soil or soilless mixes for tomatoes, peppers, leafy crops, herbs, vines, flowering plants, and other container-grown crops that benefit from calcium and magnesium availability.
For hydroponic systems, use only within a compatible media or pre-treatment program; limestone is not a substitute for a complete soluble nutrient formula. Test irrigation water and growing-media pH, then calculate application rates carefully to avoid excessive alkalinity or nutrient imbalance.

Frequently Asked Questions
Q: Can this limestone be used in an indoor grow or greenhouse mix?
A: Yes. It can be blended into soil and compatible soilless media for indoor gardens, greenhouses, containers, and commercial crop production. Test pH and follow crop-specific application guidance.
Q: Is #80 grit limestone suitable for hydroponic systems?
A: It is primarily intended for soil and growing-media amendment rather than direct use in nutrient reservoirs. Use it only in a compatible media program after reviewing pH and nutrient requirements.
