Looks like pretty much the same stuff.as always everything is delivered to uk, not nl, or delivery costs more than the product itself. However I found this http://www.potsil.com/ if you scrolldown a bit there is like 34% of posassium silica and guaranteed analysis 11%K 22%Si. Have you heard anything on that? Thanks
It may actually be a higher concentration than the GROWTH TECH version.
