Whant to grow small plants big buds

Hi I think that in autos 18/6 is better , with 12 /12 not only smaller plants but smaller buds you are going to get, if you want a small plant with big buds , some indica dominant will help or LST to control the high so you can shape her a bit 😉

18/6 or 20/4 is best for autoflowers. 12/12 will only serve to hinder her yield at the end and slow growth. Ant training will cause stress and hinder her yield. I have always topped my autos and think thats the most I'll ever do from now on as I also tried mainlining and it seemed to reduce her overall yield. You have to be quick with the training as she could flip to flower at any point but you usually have 4-6 weeks before that happens. Good luck and happy growing

I would go 18/6 with autos. If you want a small auto, you can get lowryders. They get about 12-16 inches tall. Not huge yielded but decent smoke.
