You sure grow them better than most pouch-people
Thank you everyone. Understand that everyone has different growing environment and setup. I'm still learning paphs myself.
What works well for me is getting large strong seedlings from good sources like Hilo Orchids and Mainshow Orchids.
I use RO or rainwater. I use MSU fertilizer, but I use it infrequently (every 4th watering). To avoid over water or potting media staying too wet (I mix orchidata bark, sponge rock, charcoal) - I use a pot that is just large enough for the root mass. What works for me is we get good amount of sunlight and greenhouse is relatively humid - so plants don't get too stressed out from infrequent watering. In my experience, if potting mix is always wet, plants are less likely to grow new roots.
For recently potted plants, I don't water them as often to encourage new root growth. Since I'm relatively new to grow paphs, my first step is to keep these alive. Roots are always good. Then I worry about flower quality and quantity down the road.
Here are pictures of good roots grown in a tight small pots.
For example, this is Paph sanderianum in a 3.5 inch pot. Leaf span is probably 30 inches.
Paph Hung Shen Eagle seedlings well rooted in 3 inch pot. I need to move these to 3.5 inch.

I got this at Redland May this year. Here is a small first bloom seedling. I have 6 of these. They are grown side by side, but one just decide to flower first - and its not the largest seedling.
