It will help your tricome production out alot and since u will cut back on your lights make sure to give a extra week are two in flushing since your plant will stop feeding as much with less light so it will take longer to process the nutes you are feeding herโ๏ธโ๏ธ๐๐๐ป๐ป
Autos can do just fine under a 12/12 I've even heard that the absence of those extra light hours can help mature a plant a little faster. You could always lower the hours slowly, like simulating the fall solstice.
Happy and healthy griwn.๐๐ฑ
