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 manage a tall plant with a thick stem in week 1 of flowering?One plant I ordered online was pre-grown. Now, it’s about 20 cm taller than my other plants. At the top, the taller plant gets more than 1000 PPFD, while the lower canopy gets about 500 PPFD. It’s currently week 1 of flowering. The stem is too thick to bend down.What would youdo?

Is 500 ppfd on new seedlings ok?My light dimmer only lowers to 500 ppfd. I’m starting autoflower seedlings in a space tote before I move them into my perpetual harvest tent. I’m currently propping the light on its side so that the indirect light only hits around 300-400, as an attempt to reduce light bleaching.

Will my set up work? Is it missing something major?Will my set up work well or am I missing something that can help me out a lot? Wondering if my light is big enough for three plants in a 2x4x6 closet. Are the plant pots adequate size (2.5gallon)? Should I use many nutrients with this autoflower?
