<p>In media based systems with river rock or some other natural stone or perhaps even expanded slate or shale, the media may well provide enough silica. I'm not sure but I suspect that the coco coir used by some people for their seedlings may well help with silica (I know cutting down palm trees dulls saw blades due to the silica content of those plants.)</p>

<p>However, I do know people who really recommend using a potassium silicate product for pH and potassium supplement as part of the regular rotation especially for purely raft based systems. I can't say that I have ever done that but I'm not running any purely raft based systems. Perhaps adding silica might help my plants. The Lab and testing I've been doing lately doesn't test for silica levels so I really don't know. I might have to see if one of their testing options includes a silica test.</p>
