ummm. 14W light, i'm guessing it has somewhere around 1,000 lumens. Not enough for a cannabis plant. Sure a seed might srout under that light, but you're not going to see much growth besides the poor plant stretching trying to find light.

To grow good cannabis the minimum Lumens/sq. foot should be above 3,500lumens/sq ft.

You should look into a dedicated t5 grow system. that light is more for side lighting, not to be used as a main light.

happy growing
