@Bas281, I would have to say around 250+ ppfd. 400 max. Most of veg was around 500 ppfd and I would just raise the light as they grew. However, my measuring devices are a phone app and a cheap gardening tool from amazon, so that may not be very accurate. If above 700 ppfd, the leaves don't seem to like it in my setup. Thanks for asking!
