12/12 from begining. Even if it's auto flower they need some veg time. When they go straight to 12/12 the roots stop growing and they start to flower. You need roots. When you go to 12/12 they will only double in size or maybe just a bit more. You need a root mass to get good buds.

Oh and a sea of green is when you harvest half and then put new ones in for continual harvest every month or 2 weeks. I think you mean a screen of green in which you train them to go through a screen placed over them to fill up the area all the same height. Either way you can't because that takes even more veg time.
LOC NAR on probation Reviewed by LOC NAR on probation on . Is growing my plants on a 12/12 light cycle from the beginning a good idea? I heard that it saves time. How tall will they usually grow too under this cycle? I'm using a grow box that only allows 2 1/2 feet so I figured if it does grow smaller thats not so bad. I'm just wondering if they'll grow as efficiently, and if they'll have as high a yield. Rating: 5
