Gently gut down the side of the peat or jiffy starter. Have a bucket of good water and just dunk it in and wash the peat away. Place in hydrotron or hydro medium and put in your DWC. Bring the water up to just below the netpot so the bubbles splash on the bottom of netpot. You can also hand water a little to get the roots to start heading for the water. Just keep an eye on them in case they need a little water till roots start hanging down.
