Well, I rounded up some Sodium Meta Silicate (NA2SiO3 * 9H20)
We use it to provide silicon to algae cultures, so it's pretty safe stuff. Would this work just fine? I can get it for free (just grabbed 40 grams). The person who uses it mixed it at 1 gram per liter, but that seems like it might be a bit steep. Any suggestions?
mountainman Reviewed by mountainman on . silica sands as silicate nutrients? My workplace uses significant amounts of silica sand, ranging from very small particle sizes (20 microns) to significantly larger (100-200 micron) and as such I can get access to a decent amount of it for free. Does anyone know if this would provide silicon for hydro plants sufficiently? Rating: 5
