Auto's

No, 18 hours of light and 6 hours of darkness, from day one until harvest day, is the way to go with autos.

No it will actually cause more harm than good in my opinion. Either a 18/6 or 20/4. Do not run 24/7. They need rest for healthier plants. Good luck 🌱

No, you don't need to change the cycle. Leave the lights on for between 18 to 20 hours. If you also have normal plants, you can also switch the autos to 12/12. However, the harvest can be slightly reduced as a result.

No. You can run it 24 hours a day if you want from seed to harvest

Nope. Just run 18 hrs on, 6 off the whole way thru - thats why autos seems to have such nice colas vs size of the plant. If only I could run a photoperiod plant for 18 hrs on bud... man those would be some massive flowers. So in answer- nope. They will switch to flower when ever they like. U can plant 5 seeds from same pack and they can all go into flower at diff times in theory, Some may take 60 days then flower while others may take 75 days then flower. Some could even after 50 days...So just be ready to grow them until they are ready to flower. Not much you can do, smaller pots tend to make them stay smaller and seem to induce flowering a bit sooner too but at the end of the day its genetics that dictate when a Auto goes into flower, and their genetics can be a hot mess of everything depending who the breeder is.
