James welcome yes you can do it that way but you might have better luck if you used a traditional(haha a traditional way to grow pot)method , I use the paper towel method with great success ,fold up 4 or 5 paper towels soak them ,drain so no standing water,I slide mine (on a plastic cover) on top of my cable box,this gives it warmth and dark once you see the tap root you can carefully put it in soil, keeping the soil at the right moister level might be difficult but it can be done and alot do do it that way good luck however you go
