How big is the 0.5 gallon clematis magic purple green mountain basin?

Clematis can't be changed into a big pot at once, but I think it can be decided according to the root system after the pot is removed. My two pots are normal, that is, P9 seedlings and P 15 seedlings that people often buy online. There is a comparison chart. P9 reflected after taking off the basin, and the analysis was very good. I changed it to Alice's No.5 basin, because I might have to hang it later. It's nice to have a place hanging next to Alice's basin. But for the root system, I think a deeper pot is more friendly. This Alice is a little short and fat, and her height is a little low.

P 15 Giselle, the root system is quite good. I also struggled with the caliber of 2 1 and 24cm. Because it is a balcony party, it has become bigger since it was changed too much. I compared it. The height of the 2 1 caliber Qingshan basin is similar to my current seedling P 15. The bottom is covered with new soil and the surface is covered with soil.
