what in the world makes this silicic acid so expensive? is it difficult to produce, or is it naturally occuring, and difficult to find? I believe it helps and adds yields and strength, but can anyone tell us from a scientific perspcetive as to why it costs over 1000 dollars for a small bottle? Id rather not do research myself if a fellow farmer can explain the price tag?
Also wehat else does it do besides helping with heat stress, increasing yields by a few grams a plant, and costing an arm and a leg?
