Mars Hydro Fc-6500 evo Samsung led

[Grower420John]

Hi I am using the mars hydro fc 6500 evo light and I am in week 3-4 of veg in a 5x5 tent I know PPFD should be around 400 but I don’t have any light meters do you guys know any info on what height and dimmer setting I should have my light at for optimal growth during the whole grow? I would appreciate it anyone who has used this light personally please help me out.
Thanks,
John.
