I just thought that they get used to a schedule and if that gets messed up they'll stress or something. anyways I haven't decided yet but I think i'll set up another tent and set it to 24-0 for the autos and keep the photos in the same tent and flip them to flower.Hey how are ya? Your photos only need 12 hrs of light, your autos can take up to 24 hrs of light, your yeild may suffer a bit. They will still bud, no problems there really. Happy Growing! Peace, be safe MD.
