I’d have to see… unless I have same equipment I couldnt even guess… never owned a dimmable light. I’ve raised my lights when leaves got too warm. Not used to PPFD or PAR and all that stuff either. I’d want to feel no heat at all on my hand around the canopy tops, or find a way to get near 70; maybe chasing nothing also, some would keep it all the same right til the end. If I do remember right there are different recommendations for light ppfd and temperature in different stages of budding. There’s a chart somewhere
