DWC help

I have had my babies in the DWC for almost 4 full days, and cannot see any roots starting to come out the bottom. They seem to be doing ok other than recofering from some over watering and a lil nute burn but i have heard people seeing roots after the first day in a DWC. Am i doing something wrong, the water level is just even with the botton of the plant cup.

Sounds fine, What is the medium you are using?

If they look healthy give it a little longer.

In the very bottom are small rocks like 1/2 to 3/4 in. and fish tank graval on top of that. i only put the bigger ones in to keep the graval from falling out of the holes in the bottom.

Have you seen any growth yet?

Fish tank gravel may be a little heavy but I'm not sure about that.

Some more leaves are forming but still no sign of roots,
