I can't speak much on the our door all day inside all night. But I personally keep mine on a 18 /6 light schedule. And Iset mine outside during the 18 hours of light. Just to get the better light. But there back in by lights out. Now I have read that plants grower inside produce more cloraphil(sp?) And less crystals to protect the plant from UV damage. And that the sun can possibly harm the plant bc of the uv. I started mine by setting them outside for two hours then slowly increasing the time spent outside until it was out all day. But I m by far not a expert. And I am simply relaying what I have read and my experience. If I am wrong may someone with more experience correct me.
