Dig a hole, fluff it all up and sink the pot 8in
Or go Inground.
These 200, 400, and even 800 gallon pots I see people using...it's overkill. It's not like they are growing a 25' banana tree in an arboretum over a period of years.
My dick is bigger. .....
So, I was following what container size do I need to grow a pound, which brought me to the 25 gallon. I wasn't thinking about the roots. I got a 15x15 space so I put like six 25's in it. Well I'm probably not going to be able to transplant to a 200+, but maybe. . I've seen large plants in like 10's or 15 so maybe they'll make it. I'll look for a vapedg13 post and give lots of water. And try the bury 8 inches . As long as it doesn't interfere with flowering
Overkill? I take it you've never seen a 20' plant before. If you can pull 10 or more lbs off one plant in anything less than 400 gallons of soil, then i'll side with you. Until then, do some research. My girls fill out an 800 no problem.
