Getting silicon into plants?

[knowledge]

I use Advanced Nutrients, and i was wondering if anyone knew offhand what would ad usable silicon to my aeroponics setup.
I know AN has barrcade, but my shop is closed for a week.

I will research later if noone knows off hand and let people know, because i know silicon is a good thing for the plants, that i do not think is in any other of their products.

Dude just about every quality MJ nutrient supplier has one...just pick.

Advanced calls theirs Barricade
General Hydro calls theirs - Pyrosol (now)
Dutch Master calls theirs - Silica

There are others too all it takes is a little search.

I realize this, but since conservatives came into the parliment, i need to wait til my friends shop opens, so i am hoping to find something i could use household chems to do. But in my studies I have only found three compounds they will readily accept, so think i just need to wait till the shop opens.

But how about results?
Has anyone done any controlled experiments?
Or at least some firsthand expericence? I do not have many more dollars to spend, and i know i have everything else I need and then some.
