I personally do 60 centimeters then use the Photone app to adjust the light strength , dependung on the stage. With where they are i would be doing between 500-600 ppfd. I wouldnt recommend closer than 45 centimeters because it could burn your plants.
Looking good though keepnit up.:+1:

You can do without.
