I used to run my autos 20/4 the whole cycle and some plants liked the light on the whole time. Don’t switch the light maybe increase the hours of light if anything. Autoflower it does what the name says flowers automatically without light changePlease Help? G Glue # 4 1st Auto. Do I switch to 12/12 when they start flower or keep lights on 18/6? Sorrry must sound like a different language to a newbe. Is a 12/12 needed to pack on weight?
