One more thing!
Using stabilized silicic acid products allows you to use them in stock solutions. I'm not sure if you've tried making a stock solution of potassium silicates, but it's very basic and it is almost entirely useless in a stock solution as it precipitates out of solution below about pH 11. Stabilized silicic acids can work in acidic and mildly basic stock solutions. It is generally just more versatile. But again, it's expensive. Still the most expensive fertilizer I've ever used.
And what's the penalty for not using a silicate supplement?
