How's it going everyone.. Ok, sorry for the newb question, but do I drain the water in my RDWC? I was told not to drain water. I am building a 4-5 bucket undercurrent RDWC system with a Control and Res. If draining water is recommended, do i drain all the water, or just the water in the control and or res? Please, if someone can explain to me the process it would be very much appreciated. This is my first grow. I am using a 4x4 tent with 600 watt hps. Thanks!
Also, is air stone recommended in the res?
