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.

Changing Lighting Schedule The days on the plants are since planting, so i was going to keep the vegetative light schedule until 5 weeks since planting, then start moving towards a 12/12. Is it even optimal for an autoflower to have a traditional 12/12 lighting schedule during flowering?
