I need some help-- watering and Phals

[Pilot]

Hi all--

As some of you know, I'm new to this illness of orchid growing and I need some clarification on watering my plants. When I repotted my plants, I soaked the mix in water for 24 hours before, so the medium was plenty soaked by the time I repotted the plant in it. I then gave them a drink for good measure and then let them be. So, I have no watered these guys since then! I check the clear plastic pots and found "dew" on the sides of the pot and figured they had plenty of water in the pot-- so I let them be even longer-- and now its been over a week and though I don't see dew on the inside of the pots any longer, the bark near the bottom has retained water.

So I'm apprehensive to water these things again because what if the center of the pot is also still quite moist? The roots near the plastic appear green and plump on one plant while another is looking silvery and shrunken a bit. Even though both pots have wet bark at the bottom-- should i water the one with the silvery roots?

I realize some plants will need watered while others wont and can't just decide to water all my phals at the same time-- but I just want to make sure i'm not setting up the situation for rot.

I should mention, they are above a humidity tray (not touching water) and we have a humidifier pumping moisture into the air-- so I KNOW I have to alter my watering methods as things don't dry out as fast.

Any help is appreciated. Thanks!
