The difference between photoperiod and auto-flowering recipes at Grobo is the lighting schedule and requirements.

  • Autos: 18/6 light cycle throughout all stages of your grow. They do NOT have a Transition stage.
  • Photoperiod: Has 20/4 light cycle from Germination to Late Veg. Then, once switched over to Transition and then Flower, the lights are 12/12.
