So I'm trying my very first DWC Grow. I have researched as much as possible and I am currently using a 5 gallon "root spa" bucket. what I did was take my seedling that is in a rapid rooter showing multiple roots and put that into a 4" rock wool cube. Now what I'm wondering is with a dwc setup running when there is no roots showing from the rockwool cube yet should it be hand fed until roots reach for the water level? Or should it just barely touch the bottom of the Rockwool cube? I'm concerned because the Rockwool cube seems to be wicking lots (like I could squeez lots of water from it) of water into it and I am concerned of a no oxygen condition (drowning) thus killing my little seedling. It is on its 3rd tiny just visible set of true leaves and was just put in the rock wool so no roots in that yet. Does the oxygenated water from the bucket stay that way into the rockwool? I'm thinking no myself but any input would be greatly appreciated.
Thanks
