How much light can she take

[96tears]

Shes 2 days old under a Fluence 600+ watt (from the wall) dimmable LED
germinated her at 19" below light under a humidity dome - with the light set to 15% capacity

Currently still at 19" with dimmer turned to 20% capacity

Its my first grow in this century and under modern lights and I haven't a clue......I don't want to burn them and I don't want to slow them down due to insufficient light...

If you have some helpful advice, I surely appreciate it!

Let me see if I can help you

This is your PPFD chart and at 6" you average 1000ppfd at max power. To be safe, I would start at 20-24" at full power because the PPFD or intensity will drop off at 4x the max power distance. You need more true leaves to photosynthesize all that light eventually so just raising your light to fill 6 and hanging out 6 higher will suffice but if that isn't an option the dimming too 30ish percent would work as well.
