I've had good success with 450 PPFD in veg and 750 in flower. If you have plenty of space I think keeping PPFD under 1000 during flower is a good idea. Umols to hit those numbers will depend on space being used.

those arent factors. PPFD is independent of canopy size and fixture height

i mean like strain, temp/humidity/co2, size and age and number of plants, if your goal is yield per sq ft or yield per watt, etc etc.

ask 10 people you'll get 10 different answers
