Well, it looks like most of my previous post doesn't pertain to your situation.
At minimum, I would be running new wire to your grow area. However, it's hard to tell from the picture if that would actually be enough to do what you want to do safely. It looks like you're running 240v so your amp draw would be about half of that same setup on a 120v system.
If I were in your shoes, I'd have the system inspected by a qualified electrician prior to setting up a grow room.
