Thank you for the info... I've been watching YouTube videos and the method was described as water culture. I'm only experimenting with orchids that are sickly. I like the concept of being able to see the roots at all times
I live in Ft. Lauderdale and use Orthene monthly on my orchids. I've heard that orchids can become tolerant after a while. Should I alternate with another product? Does Physan 20 provide the same protection?
