Lets say I'm growing autoflower outdoors and its 3weeks into flowering and I want to take it indoor: Is this good idea? Is this wont give much stress? What light period should I use?
18/6 would bump up the amount of.hours you are getting while still giving your plant and equipment a rest for 6 hours. I wouldnt do anything else to it to stress it after the indoor move. Are you using Hps?
100w per plant will be fine. I've read that you should "slowly introduce" the plants to the new environment to keep stress down.
Yep I also think that plant has to attune to new conditions and light period, but other guy on other post said: "you can do autos in 24/7 and you ll be fine" so if i put plants into my grow box and for about 3 days I give them 12/12 , 16/8 , 18/6 , 20/4 and after about two weeks I give them 24/7 till harvest?
Yep, if you want little popcorn buds cfl's will work just fine. Get as much light as you can to that sucker. Little lights = little buds. Good luck. J
