Monosilicic & Orthosilicic acid

After watching one of this weeks episodes of DGC, I learned the difference between potassium silica & silicic acids, in terms of bio-availability to the plants. Was very useful info, and after digging deeper, i discovered that the silica that is in Megacrop, is actually silicon dioxide which turns into monosilicic acid when added into water. I am still interested in purchasing a Silicic acid standalone product. Jerin from new millennium recommended SiLICIUM, but boy is that stuff pricy. I’m sure it’s worth it since you don’t have to use very much at all, I think he said 0.5ml/gal, but I am curious as to what other products are out there and which ones people have had success with? He did mention PowerSI as well, anyone else have experience with using silicic acids instead of potassium silicate?

The thing about silicates is solubility, especially solubility kinetics.
I cannot find the Megacrop product you describe. Link please?

Most silica is crystalline i.e. quartz. This has !extremely! slow dissolution rates at ordinary temperatures and pressures. (Consider beach sand.)
The alkaline silicate products are predissolved, which makes them well-suited for hydroponic use, though there is always some pH down needed with it.
Silicon acid can be made from amorphous silica, but I have no sense for solution kinetics.
Diatomaceous earth should be an ok source for some dissolved silicic acid. I haven’t tried it so ~elaborate shrug~.

Megacrop is the product. I knew it had silica added, but I always assumed it was potassium silicate. It’s actually SiO2 that it has though, which turns into orthosilicic acid when mixed into water.
