Living room size

Around 20 litres/5 gallons is ideal. Anything smaller (7-12 litres) really restricted growth too much in my experience. Straight into the final pot to avoid transplant shock/hassles works best too. Don't use a layer of stones on the bottom, this is where the roots end up and when they do, you want them to access nutrients, not rocks! So, soil/coco all the way to the bottom and all the way to the top too, don't leave a great ditch in the top of the pot, the coco or soil will settle anyhow.

I agree that you should start autos in the big pots Speaking from experience, on my first grow I used a 10L pot and I felt that they didn't grow as big as expected. For my second grow I went with a 19L pot and the difference was huge. Good luck with your grow, really looking forward to see these new fast buds seeds grow

Keeping in mind that I do have these sizes available atm and keeping in mind the irrigation, I'm gonna go with something I tried out before ... Sometimes I filled up the pot with a layer grind rock (maybe 2-3cm) and then put the coco/soil on top so it drains better

@unkleskunk Thank u very much, like the way u approach this 👊

Start autos in there final pot. Transplanting them can cost the plant time that it does not have to spare in the short amount of time they have to do their full grow. 👍🏻

I'm not going to tell you what to do, but I'll explain why to do it.... It's you who decides, but if no one explains the advantages and disadvantages, the decision is tough.. 17L pot A 17-liter pot for an autoflowering plant is a bit excessive; let's say the 11L pot is the standard and is made because a bigger one is hardly necessary. In that pot, it becomes difficult to control the alternation between watering and the roots that need to breathe. The advantage is that you don't have to transplant. With 7 liters or less in these pots, you can manage the dry-wet alternation very well, you can dose the fertilizers better, and you'll have less unused fertilizer residue in the soil. The disadvantage is that you have to transplant. Transplanting, let's say, when the rooting is abundant, becomes quite simple because the roots trap the soil, so you'll have a single block.... If, on the other hand, you transplant too early, the roots will be fewer, and you'll risk breakage. Talking about the most important thing "the yield," with both methods, you'll have more or less the same yield in grams, more or less. And now you decide ;)

You always need to start autos in the pot they're going to finish in... so pick your poison... but I'd go with the 17L... Have fun!
