Hey there Sike, sorry but I disagree with folks on here! 24hrs light doesn't "prolong veg time" in autos and autos are not "low yield seeds that are not worth it". In fact I've seen an auto blackberry yield upwards of 200gs and even a green crack around 300! Gorilla glue is yielding an average of 75grams . It's always worth it as long as your costs are smaller than the price of your outlaw grams right? To assure you don't stunt your plant either you don't cause it stress or you try to cause it just enough stress for it to remain in veg long enough to yield more. Usually with autos you can do things like topping to double the main cola. Try plucking any leaf with more than three fingers to keep it in veg. Use Coco medium to grow the same size plant in a smaller pot quicker. Using lst you can get great results from autos. Of course the most important thing is to choose the right genetics : some just grow bigger than others : so-called xxl autos, check them out. Hope this helps! 🚀
