CAN'T I MAKE MY OWN WITH SOMETHING LIKE AGSIL 16H FOR WAY CHEAPER?

This question is coming up a lot. This isn't an attack on AGSil 16H--simply an explanation of the differences. There are several forum posts talking about how easy it is to make your own silicate product. You can but it won't be in plant available form, here's why...

So here's some good nerdy stuff my chemist team put together. Seriously nerdy. In summary, chemistry theory is often different than practical application. While much of what the IC thread says is accurate, it's not the entire picture. Hopefully this clears up a bit.

...mumbo jumbo chemistry bullshit used to try to make it sound like they know what they are talking about more than dizzlekush...

In summary, AGSil16H is not just a “cheaper version of the same thing.” Nor is any other off-the-shelf potassium silicate or silica dioxide product. These compounds eventually will undergo transformation in proper conditions—like the acid environment created by certain microbial exudates. In longer term soil applications this potassium silicate can be effective. Much like crude oil versus gasoline, silicates must be “refined” before they can be used.

PLANT AVAILABLE SILICON
Compared to other national brands, OSA/28 contains the highest level of Plant Available Silicon. "Soluble Silicon" is the laboratory measurement of silicon in the form of monosilicic acid—the only plant available form. Higher concentration means more plant-strengthening silicon in every drop.

We knew OSA/28 was clean and strong but were curious where we stood next to other brands. So we analyze all brands on our dime to get past the BS hype and bragging that growers are sick of. Download the original lab reports below to see for for yourself.

To understand these numbers, you need to understand the testing procedure. Our laboratory partner, Thornton Labs in Tampa, developed the only nationally accepted test for Plant Available Silicon. Thornton developed the procedure in partnership with AAPFCO, the organization that decides acceptable fertilizer label claims. The procedure is highly involved, taking five days to complete, compared with single day silica/silicate mineral analysis.

This five day process mimics the same chemical mechanism plants use to absorb monosilicic acid—it is essentially a plant simulator! So while the resulting number is not the best indicator of how much silicon is in the bottle, it does tell us precisely how much silicon a plant is able to absorb from the product. There are no other recognized tests that gives this number.

Unlike most silica supplements, it is derived from pure silicon dioxide (versus a salty potassium-silicate.)

They are looking for suckers to fall for their marketing language just like the rest of the vultures.

From Bulletproof Si MSDS they use sodium silicate mixed with a bit of kelp and maybe amino acids.
