Organic Silica Supplement

I am on the hunt for a silica supplement such as Botanicare Silica Blast that is organic. Anyone?

I like ProTekt from Dyna-Gro and use it instead of the Meta-K from Earth Juice that I was using.

Not sure if any of them are 'pure' organic, just don't get that anal about it and use what works best for me.

Anyone else wanna do more than look? Thanks

P.S.
Buy their book, you will not regret it...

Silica = sand, I add a bit when mixn up soil.

Silica or sand or quartz is a trace element and only needs to be at 1-2 ppm in a balanced soil. Having higher organic mass in your soil will need and hold more elements, so if you have a high OM feel free to add more than 1-2 ppm.
