    What Umol or PPFD do you run in mid to late flower?

    I know this is an old thread, but I recently ran 1100-1300 PPFD and pushed to 1400 PPFD. I pushed to 1400 PPFD in spans of 1-2 hours at a time and then lowered back down to 1200’ish PPFD. Repeated this for the last 2.5 weeks. I did NOT use CO2. No fox tailing.
