600 watter

I recently just got a 600w HPS and wondering if it is too early to subject my 1 1/2 weeks olds to this light? is it too much? should I wait a little while?

Thanks in advance!

I've done it and they were fine. The rule of thumb here is to keep checking on them for burning.
Start them out a bit away from the light and slowly move it closer as you see fit.

If it burns it's not ready, a lot of plants act differently.
The blue dreams that I have could go right under the light as clones and be fine.
