2,5 year ago I repotted some 2 year old Japanese Maple seedlings into a wooden growbox. Now at the end of 3 growing seasons in that box I wanted to show you how they’re doing.
Here’s the original post from when they were repotted.
The first one, #2 to make it easy, I did some cutbacks on 2 years ago so it only grew to 1,5m or 5ft but it has some nice potential in the lower part of the trunk so a big cutback will happen next year in spring after the first growth has hardened off.
As you can see the lower part has some nice movement in it so it will probably be turned into a smaller size tree.
Next up is #3, This one grew up to 2,5m or 8ft 2inch tall.
This one will be a formal upright tree in the midsize format probably. The trunk is amost as thick as the coke bottle. But still al long way to go…
Shumi no Bonsai 
Wow! Is this the same maple from your 2020 bonsai wooden box post? That one had a Coke bottle too (https://shumibonsai.wordpress.com/2020/11/08/wooden-growbox-for-bonsai-why/). Do you have any more pictures to share about how big the root base is in these boxes? I worry about over potting / planting. I’m going to try some 50x50cm and 60x60cm boxes this coming spring. Thank you.

That’s the very same yes. (not the same coke bottle). I’ll try to update this post with some pictures tomorrow.
