indifferentCheers CC.
I'm not sure why they list the percentage of Potassium and Silicon, I guess if you add the two together you get the overall concentration of potassium silicate, anyone care to verify if I'm right on this? If so, it would make it 11.5% Potassium Silicate, which sounds like a decent strength. I think the best way to chose a silicate product is to find the one with the highest concentration, which would make it the most cost effective.
That's WAY beyond my pay grade. My decision to use the Pro-TeKt had far less to do with a specific potassium or silicon level, it was that this product is presented by Dyna-Gro to be the best emulsifier and surfactant for their neem seed oil product that I use on a very rigid schedule because of the problems in the PNW with mites and especially powdery mildew.
Then I began reading information about the application of liquid silicon as part of the soil soak to achieve certain goals and have been happy with my decision.
The price is certainly affordable - about $31.00 after the obligatory 'bro discount' from my buddy, Da Dude, at the local nursery.
It works for me for why I originally purchased it. There may be better options out there to be sure.
