What size pot is best for auto flower outdoor

Hey dude :) I'm following your diary as im growing Blackberry too, and outdoor too :) You just started One week before me :) I was wondering the same. I started on a 10L pot. And somebody commented my diary saying "Go for a 30L". Well... I was wondering if i should transfert from my 10L to a 30L.. Was the stress risk worth it, you know... And well, i found an article by the breeder (@fastbuds) : https://2fast4buds.com/news/best-pot-size-for-autoflowering-seeds They claim that 15L is the best. Even on their facebook. But a lot of people are commenting on their Facebook page, saying "15L ?! That's a joke", arguing 30L is the best. Who believe ? The breeder, or cannabis grower !? I'm not sure... Verry frustrating :D It's like a religion battle :D I kind of give more credit to the breeder... They made the genetic selection, so they basically grown hundreds of generations of this strain before selling the seeds. I believe they have the best experience about it. But I may be wrong. I'm not sure we will have a 100% sure answer. We will have to find the answer by ourselve... The sure thing is that you can't go wrong with a 15L pot in my opinion.

7L is the smallest you should go with , there is no high limit but the plants will switch automatically to Flo so the roots may not conquer the bigger pots like 50L

3 to 5 gallon for Autos. I've never tried outside tho so maybe stick to 5 gallon.

Hi dude.... it depend of two things.....ur knowledge about the specificities of your selected strain.... wich generation. mostly sativa, mostly indica....most of the time breeder give some information if they can grow taller or not....a super auto from stich need a real biggest pot... than a sleepy yoda 😁 same.... do you want a discret grow in your garden or do you want the biggest plant as possible.... it s generally adopted that a 15 to 20 l pot is a good size.....keep in mind that it can also be in correlation with the mix u gonna put on your pot......with a lot of auto it is strongly recommended to cut your mix with coco/perlite/vermiculite....and add in the mix fungus/bacterias...in that case in u made a miw 50% / 50% u can push to 25 l........ it allows to the roots a fastest and esay development to find nutes....and more roots = biggest plant hope this help....good luck for your grow
