Growing Phalaenopsis in Water Gel Beads

[Crucifx]

Hello everyone! I'm new to the forums and to orchids. Been mainly growing herbs and other flowering plants for about 15 years now but I have zero experience with orchids.

I came across these beautiful plants when I was with my mom looking for pot plants gifts at the nursery but I was kinda grossed out by the look of the roots but the flowers made me buy 2 or them one is a phalaenopsis aphrodite and phalaenopsis schilleriana. I'm new to orchids so I was scared I might overwater them so I looked into the web and found some people growing cattleyas in water gel bead to remove overwatering problems. I decided to give it a go.

Here is what i did:
1. Soaked water gel bead in a a liter of water with a pinch of soluble orchid fertilizer and a drop of rooting hormone.

2. I secured it in place a metal rod with an engineering plastic base for support in a glass bowl.

So far they are doing fine, the flowers are opening and humidity is no problem since I live in the Philippines and I just open the window to my room when I leave for work and I do have an east facing window and my room is bright but no direct sunlight. How do I proceed from here? Do I need to replace the beads or flush them or should I put new water with fertilizer every other watering? Will they even survive in a prolonged moist environment?

Sorry for the questions, since I'm a newbie to orchids. I managed to take some photos of it but I can't seem to post it in the forums something like a URL restriction.
