Thanks, got it. :-)

I purchased now Physan 20 (produced by Maril Products inc., USA), which is a liquid with following attributes:
- Disinfectant
- Sanitizer
- Deodorizer
- FUNGICIDE
- ALGAECIDE
- Virucide

Can I use this fungicide for the orchid germination substrate, and if, in which concentration? Or would it rather kill the seeds or baby plants? I called them already and they told me that this product is stable and won't change during steam-cooking sterilization of the substrate.
