So what is a Good Sized Pot for an Autoflower

I have heard that the larger the pot and the brighter the light the larger the plant and the better the yield...so what size is a good size?

I use 2 gal. I have used everything from 2liter to 5gal and 2gal. work great for my setup, some swear by 5gal though...I say try different size and see what your plants like as every strain is somewhat different...
 
From what I can tell .5 gallon to 1 gallon will seriously inhibit the growth of an auto. 3 gallons seems to be point at which anything larger doesn't improve yields, so going with a 3 gallon is your best bet.

HOly cow how do you make it with a 2 gallon...all my photo plants are outgrowing their 3 gallons...is there a way to keep the roots smaller? I mean they get cramped and then the plant looks all sad...

I have everything from 1/2 to 7 gallons so I might just try a few different sizes...I had actually started getting 5 and 7 gallons for the autoflowers...I thought 3 gallons would finish out my photos but it won't apparently.

5 gallons is alot of soil for autos. id say no more than 3 with 2 being practical unless your growing super autos. i just finished an auto grow with pinkbud in 1 gallon pots and its looking like i averaged about 1oz per plant.

2 reasons, 1. I use supersoil and 2. the 2 auto strains I grow don't get any bigger once I go past 2 gal... I will get no return for using 3gal over 2gal, so I don't waste the soil/space... but as I said there all different and I'm quite sure there are strains that could use bigger pots for more yield, like the 80+ day autos...

So the super soil makes the plant grow less roots? I think I just need fewer roots...I mean I know they say the more roots the better, but I literally just had a rootbound plant in a 3 gallon pot..alot of people finish in smaller, how? Why? I want to use a smaller pot, how do I accomplish this without killing my plant? It isn't that I am looking for a way to make a better plant or what not. I just want to know what I should conceivably finish it in...? I think I will go with 5 gallons...it is supposed to finish between 60 and 70 days so...I am going to hope that a 5 gallon will suffice.

004.jpg011.jpgThese two plants are now 47 days old. These are both autoflowers(Onyx) they are from the same batch of seeds, and they were planted at the same time in the same soil. They were both grown under exactly the same conditions. The only difference is the one on the left is a 3 gal pot and the one on the right is a 5 gal pot. The shorter onyx is a pretty solid bud from the main stem up and it's only 15 inches tall. The bigger plant now has a huge main cola and several large secondary colas. (these pic's were taken well over a week ago)The 5 gal pot looks like it will have at least 20% more bud than the 3 gal pot. Anything over 5 gal is pointless for auto's because they just won't get any bigger in a 7 gal pot vs a 5 gal pot.

Hope this helps

i forgot to mention that the bigge plant is almost 30 inches tall, fully twice the size of the other. This was an intentional experiment to answer the same question you asked.

I'm having similar results with the Big Devil and White Dwarf, however on the white dwarf(even though the seeds were from the same batch) grew with two distinctly different pheno's so I can not use it in the experiment.

Nice comparison man I been meaning to run a side by side.I know after various grows of the same strain 5 gallon pots will generate bigger plants than 3 gallon as Ive tried both.Hopefully ppl will start beleiveing lol. This is a wos afgan cush ryder at 56 days in a 5 gallon smart pot.Farming 075.jpg

That Afghan Kush Ryder looks like it has some excellent branching. I grow autos outside in 3 gallon pots, but might have to give 5 gallon a try. I was planning on running Paradise Seeds Pandora again since I had such good luck with it last year, but I keeping seeing these awesome pics of Afghan Kush Ryder.
