Do I have to sterilize the mount first to make sure there are no microorganisms or fungi? If so, how would I do that?
Do I water them as in DRENCH them or water them as in mist them, or both?
No you don't need to sterilize the mount. Just wash off the dirt and dust that might keep the roots from attaching themselves. You can use either method of watering. Whatever is convenient for you. I use a misting sprayer most of the time but make sure you get it good and wet. I've also occasionally taken the mount to the sink and soaked it under the faucet but be careful not to bang the plant around before it's attached to the mount. I've never dunked it in water because I don't have a container the right size to do that and it seems like too much trouble. My phals have been slower to attach themselves than my cattleyas. It took several months for them to attach well.
