Silica Earth Volcanic Silica Minerals Micronized Powder - 40 lbs

Dry Silica, Calcium and Magnesium for Substrate and Liquid Feeds - 40 lbs

Silicon is present in most native soils, but plants can only take it up in a soluble form. This volcanic mineral powder supplies silicon dioxide with calcium, magnesium and a spread of trace elements. It is micronized to a fine particle size and is approved for organic agriculture, so you can add it to your feeding program with fewer unknowns.

The 40 lb unit suits growers who add silica to every substrate batch or feed tank. It fits regular indoor growers, larger gardens and commercial cultivation, where a bulk supply lowers how often you reorder. Hobbyists who want a trial quantity will find this a large starting point.

Key Features & Benefits

• Silicon dioxide with calcium and magnesium — supplies silica together with two secondary nutrients and trace elements.
• Micronized dry powder — mixes into substrate or liquid feeds without handling a liquid concentrate.
• Water soluble and wettable — works in feed tanks and other liquid applications.
• Organic agriculture approval — suits growers who follow organic programs.
• 40 lb unit — gives enough supply for repeated use across larger spaces.

Who Should Use Silica Earth Volcanic Silica Minerals Micronized Powder

Use it if you grow in soil, coco or rockwool and want to add silica to your program. It also suits growers who prefer a dry product over liquid silica. Commercial operations and serious indoor growers will get the most from the 40 lb size.

Frequently Asked Questions

Q: What does this product add to my plants' feeding program?
A: It adds silicon dioxide, calcium and magnesium along with trace elements. Silica is not a primary nutrient, so growers use it alongside their regular nutrients rather than in place of them.

Q: Can I use it in soil, coco and rockwool?
A: The distributor describes it as a dry additive for soil, coco and rockwool substrates. It can also be mixed into liquid nutrients, compost tea and foliar sprays. Follow the manufacturer's application rates.

Q: How does a dry powder compare with a liquid silica?
A: A dry powder ships and stores as concentrated material without added water. A liquid product is ready to dose but is usually heavier per unit of active material. Choose by how you prefer to mix and store inputs.

Q: What does micronized mean?
A: Micronized means the material is ground to a very small particle size. Here the distributor lists 2-4 microns. Fine particles wet and disperse more readily in water and substrate.

Q: Is it suitable for organic growing?
A: The distributor lists it as approved for organic agriculture and as OMRI and OIM registered. Check your own certifier's requirements before use.

Q: Where can I find safety information?
A: A safety data sheet is available for this product. Review it before handling and storage.
