Makes a good pH up have to say. I'm using OMRI certified potassium silicate.
I believe you can observe improvement from using it. Convinced I've seen the difference myself. If only a little.
Personally I take the "availability" of Si products with caution. (the same is said for garden lime)
You don't necessarily want or need an Si product that's so readily available, as some Si products are.
I don't ever go over the manufacturer's recommendations either.
If it helps against pests/disease, whilst producing stronger, more tenacious plant fibres, then I'm all for it.
My only concern about Si is in end product.
Will using Si products up until harvest adversely affect one's health?
Is it legal in commercial operations to do so?
It's a genuine concern I do have. If anyone can inform me.
I've seen the general advice is to stop Si use a few weeks before harvest.
Using 1mL/10L solution.
Tempted to run it until harvest anyway, from now on.
Would appreciate input from any person who knows.
Cheers.
