It's not what I would have picked for a light, but it should be fine to grow out your plant.
I wouldn't have mixed two different types of medium either. Maybe a FFOF grower could chime in better but the package looks like it's pre-loaded with nutrients for the plant. If that's the case you shouldn't need to add nutrients for a while, but you also mixed it in with a coco medium (Mother Earth Coco w/Perlite) so who knows. It's best to stick to one type of grow medium as they have different requirements for optimal growth. Good luck!
