How much PAR for seedling?

Hello all! One of my baby Gorilla Glue’s opened this morning and I’ve got her all set up now. I need to dim my SE3000 down a lot and am wondering what PAR reading would be good for a new seedling? What’s the max? I have a Photobio Phantom PAR meter. Thanks much!

For a seedling I’m sure it’s around 200-500 ppfd, you can slowly ramp it up. This is what I have saved for myself.

Seedlings: 200-400 ppfd

Vegetation: 400-600 ppfd

Flower: 600-900 ppfd
