Yes they are but the AirPots are not in yet where I get them from so I have to wait till then.
Tease those roots apart a bit when you do though mate eh? They must be quite root bound by now, have you had a look lately?
If you`re going to have to wait for a while I`d seriously consider getting a standard plant pot one size up and give them roots a break.
How long have the older ones been in the pots?
