i made tons of hypertufa containers and purchased and divided many plants to go in them(mostly semps and suculents as the troths are too shallow)
would it be a problem to plant them up now as opposed to next spring?
I see you found the Hypertufa Forum. I think if they are going to be outside that the plants may not have enough time to settle in before the winter freeze and thaws.
You might also try asking at the link below too.
