can I grow a photoperiod alongside autoflowers??

Hey UpInSmoke420, If you wanted to grow autos and photos together in the same tent, then switch from 18/6 to 12/12 when the autos finished flowering you can do that. I'd say to try and trim and LST your photo plants as they will get quite big with that long of a veg cycle. 8-10 weeks ish. You can also switch the lights earlier to 12/12 even before the autos are finished to trigger flower in the photos earlier if you want. The autos will flower automatically regardless of the light cycle. The only down side is, you may suffer lower yields with them, but if your using any other tools, like LST, Defoliation exct, you can gain that extra weight back by the plants mass being bigger then a normal untrained plant. I grew a auto with 3.7oz on it, was my biggest yet. I'm sill an armature but its possible, all my other autos previous to that was 1oz a plant give or take. m0use
