Hydro is more my thing, but I do get clones or seeds going in soil sometimes.

I compact the soil very slightly, just enough so the clone will stand up well when a small fan blows on it. Upon doing so, water thoroughly until soil is good and wet. It should be running through the bottom. Put a very small amount of SuperThrive or some other B1 into the water. Solution and dirt should be PH 6.5-6.8. Let that dry out almost completely, or until you see the first signs of thirst (droopy). Then you can water again using a small amount of food, 1/4 strength or less, and increase to full gradually over a month or so.

Works well for me.
