The beginning of DWC when roots aren't long and reaching deep into your bucket you need to be careful. I have had a plant die in a 24-36 hour window left unchecked due to the roots drying because the water level wasn't high enough. I was so mad at myself lol, for not adding more water. Once this happens, there is nothing you can do. I have found it is very hard to drown plants in DWC as long as you have an air pump and water isn't over flowing.... Anyways just a heads up/
