Hi!
I was watching some Thai videos about orchids and came across one which was showing how to de-flask orchids.
To my surprise they use Betadine as fungicide.
It makes sense as Betadine is a strong iodine based antimicrobial solution but I wondered if anyone here has used it and if it is better/worse compared to normal commercial antimicrobial solutions in the market?
Can it be used on bigger plants too?
