I use ordinary pots, stood in a tray of water/nutrient -saves messing about drilling holes, also means ordinary cheap pots,and that there is a greater volume of water,( I can leave them for a week if I am away, without concern) also easy to change the lot - no risk of strong solution being trapped in the bottom, etc. I also use coarse Perlite rather than the larger hydroton, and this holds enough water so that when I dry a plant off for a winter rest - if its that sort of plant - it takes some weeks to dry out naturally. Likewise when i start to water again I first plunge the pot, drain, then stand it in a dry tray - not as wet as the later time when standing in a tray of water, good for encouraging a new root system to grow. Also the tray allows me to check and adjust pH and Ec and be sure that what is in the pot is exactly what I want.
Just minor tweaks you might call them.
