Well, back to the original topic
Sade, I checked your climate data, and I think you can expect very good results from S/H.
I have a dozen Vandaceous and around 30 Phal in either pure LECA, pure rockwool or a blend of both, and they're really going strong.
Our climates are roughly similar, albeit yours is a bit warmer and more humid, which is perfect for what you grow.
After a few trials with the S/H method presented on Ray's website, I made a few adjustments to the technique to better fit my needs.
Because RH during the day here is almost always sub 20%, and wind permanent, the top layer of the pot would dry very fast, giving a hard time to seedlings and plants with new roots.
The S/H variation that works best for me consists in standard, super cheap horticultural pots with holes in the bottom, with a blend of LECA/rockwool, and a top layer of rockwool.
Heavy drinkers are in a saucer with about 1cm of water, others are kept above a tray that collects water that drips when flushed (which is arguably S/H at all).
All are sprayed daily, and heavily watered once a week minimum.
Don't worry too much about pH, container shape and whatnot, you'll soon know what to tweak!
