Also, I just read your other questions for other people, and no, not a bag over each leaf. Think something like this:

If you want to watch a good video on how to do it, go to YouTube and type in "How to save orchids with no roots."
Regarding roots telling you when they're thirsty, they will go from being plump and green to kind of silver, like this:

Next, I have never heard that about chlorine, and you could damage the plant by doing that if the chlorine doesn't leave the water... It would also receive salts and other yuck in your water (like calciums and so forth). A lot of people use distilled water or rain water. I've got a water filter on my faucet and I use ONLY filtered water on my guys. I don't know that I'd trust tap water with chlorine in it. >.< Gallons of distilled water are pretty cheap at grocery stores.
Final thing on phals, they grow pretty slowly. So be patient.
I have a guy that I have dunked in KLN TWICE and it hasn't done anything. It hasn't grown new roots...buuuuuuut it hasn't died. Still waiting that one out. It might take 2-3 weeks if you do a hormone dunk before you see anything, maybe a bit longer.
If you don't want to use a humidifier, you can mist them. I do it 3-4x a day. Idk if it helps, our temp/humidity meter is all wonky from not being correctly calibrated when we moved last, lol. But I'd *like* to think it's 65% humidity over there! xD My guys' leaves seem to be happy and they seem generally pretty satisfied over there where they are. Grouping plants together also assists with raising humidity because of respiration, as I understand it.
Hope all of this helps.
PS: DEFINITELY read The Phal Abuse Ends Here. It's such an informative thread! It took me about a week to get through it cuz I read it on and off but it's sooooooo worth it. In fact, I may read it again once I move and start setting my guys up under grow lights.
