Newbie questions regarding semi-hydro setup

[Kingak]

Hello,

I've been doing some research on how to setup semi-hydro growing environment for phals with leca, and I'm a bit confused about the best (least chance of root rot) way to set this up..

1. should I use a clear container with drainage holes and sit it in a tray of water? or a container with no holes and pour water in it? (and does it mean that there's a chance that the roots at the bottom will be sitting in water?)

2. do you let the water in the tray or pot dry first before giving it more water?

3. is a water wicking system / self watering pot beneficial?

4. do you still need to report every 1-2 years?

Thank you!
