I need help please. On the left I have a mystery autoflower that I'm hoping is in her final weeks. In the middle I have a 3-4 week old northern lights fem photoperiod that I planned on putting outside with 5 others but only 1 sprouted so I decided it's not much worth the effort of putting out by itself. On the right I have a 5 day old chemdog auto. I was planning on starting another auto once the mystery is finished but also was wondering how it would effect the chemdog auto if I was to transplant the photo fem to a 3 gallon and veg her out on 20-4 light schedule and then flip to 12/12? I'm fully prepared to ditch the photoperiod and start another auto but wanted to give her a chance at life. I just need to know which would be more beneficial. Thanks in advance. I know you all can help.

It will simply get less exposure time and therefore need a higher intensity.

See the difference between autos and photoperiods is simply the requirement of a long enough dark period to initiate and maintain flowering for a photoperiod. Where an auto does not require a 12/12 cycle to initiate or maintain flower

The light requirements are similar in terms of DLI (daily light integral) which is a calculation of intensity and duration of exposure.

So if you go 12/12 you need to increase the intensity to make uo for the lower duration if exposure. Which you do for photoperiods anyhow.

So long story short an autoflower can get away with half the light intensity if you run 24/0 than a photoperiod. If you run an auto 12/12 the just need more intensity like photoperiods do

Thanks for the feedback. Unfortunately my light is maxed out now and the ppfd at my plants level was 535. I don't think thats very good but I may be wrong. I'll check the DLI meter when i get home.

600-900 is acceptable for flower. Your not far off and yield should be decent

You can flower a photo under as little as 14/10 but to be safe go 13/11 and that will give an extra hr of light to help compensate for a slightly lower than optimal intensity

So 13/11 should be fine to flower the photo all the way through? It wouldn't adjust and reveg?

Aqua Man said:

Yup should be fine
