torch404} ....trust me, and the manufacturers, it is....foliar is the best and fastest way to get it in there! Right where the plant needs it most,...
I belive that the manufacturer told you that, but as you mentioned earlier most silica products are potassium silcate and then in the root zone are changed in to silicic acid. what produces that change on the leafs? Most of these products are essentially sand in a base solution and don't absorb quick.
I don't know for sure either way, maybe I'm just thinking too much. I usually add a bunch of DE to my soil mix for Silica needs. I'm not even sure where my protek is at the moment now that I think about it.![]()

Oh well, let the physiologists grind that out! All that matters to us "farmers" is the great result from including it !!
