RAW Silica contains 45% silicon dioxide, one of the highest concentrations available in a flowable, water-compatible form. pH neutral and clean, it can be used throughout growth and bloom to support strong stems, resilient cell walls, and improved crop performance.

Expanded Description:
Silica is often called the support element in plant nutrition because it reinforces cell walls, strengthens stems, and helps plants stand up to stress. While many silica products are based on potassium silicate, RAW Silica is different. It’s a biogenic silica—naturally flowable, pH neutral, and highly compatible with beneficial microbes.

  • Structural Support: Reinforces stems and cell walls for sturdier growth and better resistance to stress.

  • Microbe-Friendly: Unlike harsh silicates, RAW Silica is biogenic and sometimes even used as a carrier for microbial inoculants—making it ideal for living soil and bio-active systems.

  • Flowable & Versatile: Some particles dissolve immediately for fast plant availability, while others remain in the root zone for gradual release.

  • pH Neutral: Will not cloud solutions or shift pH, unlike many traditional silica supplements.

  • Flexible Application: Can be added at any stage of growth or bloom, in soil, coco, hydroponics, or foliar programs.

RAW Silica is highly concentrated, clean, and available in sizes up to 25 lbs. It integrates seamlessly into all feeding schedules as a cornerstone supplement for plant strength and resilience.

Want to learn more? Watch agronomist Harley Smith’s video below, where he explains why RAW Silica’s biogenic form is unique, how it stays pH neutral, and why it’s friendlier to microorganisms compared to conventional potassium silicate products.

Sharp and goes well with fancy, or jeans. Looks great for the price.
Size: Large, Color: Black
As tweed Herringbone vests go, this is rather nice and fits well. I'm 5'10", medium build and the Large fit nicely. I ordered it to go with my Oktoberfest Lederhosen outfit (worn to Oktoberfest in Munich), and it worked well. It'll also work with jeans. It's not some high quality piece, but for the price, appears more expensive than what it costs.

Nice Qualtiy for the Money
Size: Large, Color: Light Blue
I originally ordered this vest in XL based on other reviewers' suggestions to up size, but I returned it for a large. Vests should fit snugly and not be loose. I'm 5"9" and 175lbs and the large was a good fit for me. The material is not as heavy as I expected based on the photos but it is not flimsy. It is well constructed with a nice liner. For the money it is a really nice item. I have nicer vests but then they cost several times what this one did. Overall, I am very happy with it.

Not terrible for the price. Not super high quality.
Size: 4X-Large, Color: Black
Not bad for the price. Fits a size smaller. I can wear it standing up, but need to unbutton it to sit down. I have very little faith in the buttons. The sewing looks rushed. I may cut them off and replace them. Brown buttons with a black vest? Odd choice. Not sure what the half moon pocket is for next to the button holes.
