Hi Mary! I have switched about 4 of my orchids to s/h and so far I love it. I purchased all my supplies from Ray's site and I didn't find it very expensive at all. The clear pots are super cheap (or you can make your own) and compared to regular bags of medium I find the prime agra very inexpensive as well. Plus you can keep reusing it and you don't have to dump it if you need to repot. The only downside I can think of is that you have to time the placement into s/h a little more than regular repotting into bark or moss. You should definately wait for new root growth before trying it. You should do that anytime you repot but I think it's more so with s/h. Maybe just start with a few and see how they react. Thats what I did. My onc. Sharry Baby LOVES it and I didn't even wait for new root growth. I also have 2 phals in it and they are doing really well so far. At first one of my phals pouted and got really droopy but I started misting the surface of the prima agra every morning and it has perked right up. Hope that has helped you a little. Sorry so long!
