Hello friends. I'm currently growing in DWC and I have 6 more weeks till harvest. So far so good. Thinking of building my own RDWC setup for my next grow. The setup by Gary from PAHydroponics seems quite effective ( https://www.youtube.com/watch?v=W8NQ...=PAHydroponics ). How would you guys compare this setup to undercurrent RDWC? Any suggestion is welcomed.
