Help please how do i get rid of green mold on my soil??

Its most likely algae? I had some grow on the top of the peat with my last batch of clones. Its not the most deadly thing ever, but not a good thing either. You can get rid of it by increasing airflow, and reducing the amount of light that hits the soil/top of your growing medium.

Some people use a small amount of hydrogen peroxide in their water to prevent algae amongst other things from growing.
 
quit letting the light hit it.. algae needs air, light, and nutes to live.. take out one of the three and it will die
 
also lower the humidity considerably, water a little less if u can, and a fan will definately help nd if u can manually get it off now id do so
 
Put aluminum foil over the dirt, it won't hurt a thing and keeps the light off the dirt and the algae goes away.
 
it just eats your nutes and increases risk of root rot, like was said, tin foil takes care of it nicely within a few days.
