Silica

[jiggerman78]

After looking through a package, i pulled out a package of silica, which almost every single product in the world has. Than i got to thinking that since silica is used in nutrients is it possible to use the little pebbles that came with my package. I know that when plants uptake it they respond by building a thicker wall to resist various problems. Has anyone does this i've searched everywhere i can?

i dunno what your on about but i use all those silica sachets in my growbox to keep the humidity down. my grandma had some new furnature that i assembled for her and there were hundreds of silica sachets. i knew they would come in handy for somethin
