That looks nice!
but the ones that are sitting in the same tray risk sharing whatever one plant may have, right?
Anyways, I also love paphs and have quite a few. Mostly mottled leaf types, complex hybrids, some novelty cross, and one species ( Insigne Sanderae). I don't have multi-florals (mostly because they are usually quite big).
Mine are two types of mix, straight sphag or repotme paph mix (coconut husk chips, hydroton balls and others). I plan to venture out to semi-hydro with some common ones that I wouldn't cry over in case they died. lol
Currently, mine are growing mostly by south window protected by sheer curtain or by taller plants. Some are under LED and even on the floor where it might be a bit too dark for them. It is sort of an trial.
The ones by the south window and under LED grow really well.
I water them when the pots feels light when lifted up. I like to go around and lift pots quite often. lol
I use tap water for all of them. I would fertilize using Jack's classic balanced fertilizer during the growing season. very dilute every time I water.
Summer is brutal indoor. I would run large fan when the temperature goes above 85. when it goes above 100, I run A/C.
I don't have any temperature issues during winter. It is nice and warm. not too warm and never cold.
Apparently too warm for most of my complex hybrids as they have been growing really nicely, but do not flower well if at all. only the white varieties has flowered and one green one. I got rid of some that haven't flowered for over two years to make space for something else.
This year, I plan to leave my complex outside until first frost to see if that will help to set buds.
I even tried one month of refrigerator "treatment" with one of my stone lovely, but it didn't work.
