Converting to S/H culture, what products can I buy in Europe (Belgium)?
As I'm having quite some orchids now, I'm thinking of converting them all to S/H culture. (or at least give it a try with some of them)
The LECA medium and the pots aren't hard to find. But where can I find the different chemicals like Physan 20 and Dyna Gro KLN in Europe?
Also, what kind of fertilizer will I need after they're repotted?
