armor si general to use in organic land?

This product can be used in soil no problem. It may not be necessary as most soils contain a lot of silica naturally - but no harm in using it at recommend dose. If you wish to use a natural source of silica in soil, I'd recommend vermiculite.

It is silica and is most likely capable of any type of growing method. You want to limit the silica you provide though. It obky takes a small amount each feed. Too much your plant will become tough, and buds will be tough. It adds strength to plant. So there is a limited amount that you want to use at a time. 👍🏻

it's plant avaiable silica, so it will work in soil too.
