When an individual spends as much time or more critiquing/knocking another's method of growing than spent on what works for that particular individual... It raises my caution flag.
Jason is There, but not HERE where I am. What works for one individual, with their particular methods, quirks, environment, and culture will not work for another unless they adapt those same qualities. Even when growing in the supposed same climate or environment, there are variables.
No, I don't agree with a lot of what HereButNot says. I've read that blog countless times as it comes up here. The minute he indicates SH is an "always wet" environment, I don't have the energy to spare reiterating and picking apart his critiques of what another might or might do. But maybe I should... then I could just do a cut/paste of my opinion when the subject comes up. Goals...
I live in Zone 6a, same as my buddy DollytheHun. We grow and have grown orchids for quite some time, and neither of us would want to grow the same way. I've grown almost exclusively SH for over ten years. I think growing orchids is similar to lifestyle choices. There's more than one way to do it. For me, it's SH.
The longer one grows a certain way, the more familiar they become with that method and how to tweak one's culture for a particular plant's needs. I grew in a mainly bark mix for years. For ME, semi-hydro is easier, quicker, and less time consuming, because I've worked hard at making it less time consuming. I've grown up to 170 +/- orchids both in a mixed bark medium, and in SH. With age and lack of time, I've pared it down to never have 100 at a time, and try to stay around 80.
Quick answer to your question, Sade, "I would like to comprehend within a general principle what kind of plant developed better in SH in a High humidity environment."
Anything you grow will develop better in a higher humidity, and works well with SH.
Now, I'm off to the doctor so he can view his beautiful work on my latest cataract surgery.
I'll likely have more opinion later today.
