Silica Earth Volcanic Silica Minerals Micronized Powder - 5 lb

Dry Silica Supplement for Soil, Coco and Rockwool - 5 lb

Plants take up silicon only in a soluble form, and many growers struggle to supply it with the usual feeding routine. This micronized volcanic mineral powder supplies silicon dioxide with calcium, magnesium and trace elements. It is fine enough to work into substrates or mix with liquid feeds, and the listing carries organic agriculture approval.

The 5 lb unit suits a regular indoor grower who wants enough powder to try across several cycles, or a small operation testing silica supplementation before scaling up.

Key Features & Benefits

• Micronized particle size of 2-4 microns — fine powder that mixes readily.
• Silicon dioxide, calcium and magnesium — supplies minerals in one dry product, with trace elements.
• Flexible application — works in soil, coco and rockwool substrates, or mixed with liquid nutrients, compost tea and foliar sprays.
• Organic agriculture approval — registered with OMRI and OIM for organic programs.

Frequently Asked Questions

Q: What substrates can I use it with?
A: It is intended as a dry additive for soil, coco and rockwool. You can also mix it with liquid nutrients, compost tea and foliar applications.

Q: What is monosilicic acid?
A: It is the soluble form of silicon that plants can take up. This product lists a monosilicic acid content of .45%.

Q: How fine is the powder?
A: The listed particle size is 2-4 microns. That fine grind helps it blend into substrates and liquids.

Q: Is it approved for organic use?
A: The listing states it is OMRI and OIM registered and approved for organic agriculture. Check your own program's rules before use.

Q: How much should I apply?
A: Use the manufacturer's recommended application rates. Those are available in the product documents, and the safety data sheet covers handling.

Q: How does a dry silica compare with a liquid one?
A: A dry powder is concentrated mineral without added water, so storage and shipping are simpler. Liquid products are premixed and ready to dilute.
