Nice!
RE: Cheesus - I have wondered about this too.....as I have 2 Multipot Dragons going.
I don't know about root bind, but it seems like you could grow them both out in the same pot and just prune the inner stuff as needed
for space and light penetration...IDK specifically though.
It may be the case that with these Dragons anyway, that their smaller stature is conducive to allowing it.
Try it and lead the way! (for me anyway, if I get 2 females.)
5 gallon EZ roots felt pots with the frames.What size pot are those dragons in dude?
