Question about LED grow lights (general)

I have a grow lights currently running 1000w on 15-amp circuit in one of my grow rooms. Is it possible to upgrade the amp circuit on that room so I can set up more grow light or do I have to upgrade my electrical panel altogether?

I'm a newbie when it comes to using grow light as I always been growing seedlings outdoor with natural light. I'm just scared that I might go beyond and cause future damages
