what should my par levels be at in flower

[Tabi]

If I’m running 1500 ppm of co2 can my girls handle 1200 PPFD at canopy during flower

temp 74F
Humidity 50%
co2 1400-1500 ppm

Oh definitely. As long as the heat isn't too much, they can go up to 2000 or more especially if your pumping that much CO2. Check the ppfd on a bright sunny day and you'll understand what I'm talking about...

I'm curious about your EC and what medium you're using?

With some strains you may get bleaching of the flowers having too high of ppfd. Perhaps it would take more than 1200 though but something to watch for.

I’m not sure Of the EC but I’m using roots organic 707
