yes, cover it in soil about 5 cm, it doesnt matter what way you putt it in just cover in bit of soil. remember red plastic beer cups are great for starter containers , this way you don't have to transplate 5 times before sexing, The red beer cups are big enough that you can grow your seedling to the point where you can sex it, when it gets root bound then transplant to 1 gallon pot's. when that's root bound transplant to whatever size you want.
