A Big Thanks to Ray!
 

I recently started switching many of my orchids over to s/h, and more recently started using K-Lite and Kelpmax as per instructions (more or less!) and am now seeing definite improvement in practically all of the plants so treated. The only exceptions are a few that are in winter rest. Root growth, in particular branching of roots has accelerated tremendously, and now the other parts of the plants are starting to catch up. I would definitely say that this transition has been the single best thing I've done for my orchids to date. My deepest thanks go out to Ray! Now if only someone could figure out how to do Stanhopea in s/h........

I've also seen a huge improvement in my orchids since switching to K-Lite and regularly using KelpMax. Over a year ago. I also started using Inocucor a few months ago, and two mounted phals which had been doing poorly (and had been growing even worse when potted, which is why I tried mounting them) have started to grow very nicely, with two new leaves each and tons of roots.

I didn't mention Innocucor, because I started using it quite a while before making the switch to s/h.

I've always wanted to try grandiflora in this s/h. I think it would work because the flowers grow upwards (more or less). There are also allies (Peristeria, Houlletia, etc.) that have upright spikes which would do well!

I'm strongly considering moving my Gongora species and Sievekingia fimbriata into s/h as they also spike sort of upwards. However I've been giving the problem some thought and I have an idea for keeping the pendant types in s/h that seems worthy of some experimentation.

I don't think there's a particular issue with plants that grow pendantly, whether that's the foliage, or spikes that start up and cascade over the edge of the pot. The problem is with plants that send their spikes down through the potting medium, expecting to emerge from the bottom.

I obviously misused the word "pendant", as the Stanhopea that spike downward are the ones I'm referring to.
