Have to say though, our customers keep them in the packaging for up to 3 weeks.... ..... we do use chrysal prof 2 in the initial water that they have in the bottom,,, and supply food etc with it,,,, have never had a customer saying that they had to take them apart because they fall over....... mind u the Le pouchettes and now the castle vases help

will give these a go though and maybe let you know how it turns out cheers for the help folks.
