20 hours, how many seconds in 20 hours? 60x60x20=72,000s Ppfd x 72,000s will give you the exact micro moles. You want 40 dli? 40,000,000÷72000= 555.555 the recise ppfd to use to reach 40moles in 1 daylight cycle.

The max DLI you want to put on autoflowers is 44 without CO2. You can experiment with that number but that will get great results.

I'd say between 30-40 Dli. Sometimes they will take the top end of that scale Sometimes the lower end. Start at 30 and see how they react.

How to keep room dark during flower?
How important is it to keep the plants in COMPLETE darkness during lights off during flowering? Thinking of running some ducting with cut-to-size furnace filter out the vent hole on the side of the tent which supplies air right now. Will that be enough?
