What is the best pot size for coco??

Hi I was just reading another thread and they brought up pot size. So I am wondering what is the best pot size that you use and why? I currently use 2 or 3 gallon pots

First, it's going to depend on the size of the plant.

That being said, it's amazing what a 1 gal smart pot (fabric) will be able to produce if you're able to keep it watered. I have a few males that are about 4ft tall, and very healthy (middle of flower), all in 1 gals. I pull a fan off today that was about 11 inches across. They kind of look funny, and they can tip, but it works.

I've also grown some really big coco plants in solo cups, to the point that they would tip over on a pretty regular basis. I had about 2ft plants in solo cups (they eventually were upgraded). :)

Best!

I'm going against the trend on this forum and say ime bigger is better we have used everything from 55gal pots to 2 gal. It seems bigger pots have less issues with salt build up. Rule of thumb I follow now is 15gals of mediumevery elbow I'm shooting for with 2\light. That's with coco/perl 60/40

ive had many 25gal pots root bound in twelve week veg. I guess it depends on veg time ive always done flip rooms with trees

plant size & veg time is the main contributing factor in sizing your pots of coco . if you figure that each gallon of coco will give you 3 oz (minimum ) of bud (strain & veg time dependant of course ) that 3 zips per gallon is a pretty good starting point to figure out what size pots of coco to use .
i use 3 gallon pots with a month or more veg & shoot for half pound plants .

What Dansbuds says rings true to me. I cut the top off containers I get cat litter in. Guess they are about 3 gallons or so. Found these little white plastic trays for them to sit in maybe 4 inches deep - works great. Use pool toys I found at the dollar store to collect the runoff. Simple cheap and easy.

i'v gone from 9l =2g into 25l=6gal tree's , much better looking plant and reduced number , less work suits me at moment. 2gal transplant into 6gal gets topped up with recovered coco. 5 to over 6ft.

I went from 20g soil, to 10g coco. Same plant numbers, same dialed room, better dialed nutes, and my yield dropped and flat lined 3 runs in a row. I moved up to 15g coco, dtw, 3-4 feedings/day, 6 to 8 week veg. Goal is 12.5oz plants as a minimum. I run 1.8 plants per light.

There is no easy answer, without knowing your space, environment, plant numbers, and most of all your goals.

I run 3 gal smart pots and typically pull 6-8 Oz per plant in SCROG. I have let some plants get a little out of control in the past (too big for SCROG setup) and have pulled as much as 14oz (dried) from a single plant. The variable seems to be veg time more than pot size IMO

Agree with you

Veg time and feed frequency are the variables for optimum, but you would normally have to factor in plant count and grow area you have
