Hi!
As many people here, I watched Bruce Bugbee's educational videos, where he suggests using a medium made of 50% peat and 50% vermiculite and says that vermiculite has lots of silica for the plant.
While researching about this, I found this site which says that vermiculite doesn't work as a source of silica ("sand, pumice, perlite, vermiculite, and rockwool are technically silicon materials, but the silicon is hardly available to plants and they won’t offer health benefits"), and suggests using diatomaceous earth.
So... contradictions in the web, that's a new one... xD
What do you think about this?
