Ok, both from posters here and the leading manufacturer of wholesale agricultural potassium silicate bulk all say it polymerizes at a pH lower than 10. At first I thought, "Why did I just see it dissolve so quickly in room temp. distilled water?", one answer of which tried to hit me: "I suppose H20 rapidly went up to 10 as I added K2OSi?"
... although if it weren't dissolving some how would it up the pH anyway...?
Also, most commercial aqueous solutions except the super-diluted type warn you to stir in your "6% potassium silicate liquid concentrate"(etc.) before anything nutes, so it doesn't cause goodness knows what to precipitate out the other way around before it thins out in the res, but tell me this:
We don't grow our plants at or above pH of 10 (below which soluble silicates supposedly polymerize into useless silica gel, even as stated by manufacturer!)
What's to prevent the potassium silicate from doing this as soon you add it, even to plain H2O before nutes??
I don't understand!
Is there some magical, unlisted stabilizer in the liquids sold vs. plain "powder" or "glass" + H20?
I will admit some further confusion because there is documentation stating to get true solution you have to use heat and pressure and water, not just stir in potassium silicate.
Thanks in advance
