New plants from nursery.....Repot?

[barry593]

Hello everybody,
I have just received several orchid plants from nurseries and wondering if I should repot or wait until fall. The plants are Catts - one to two years old and in green standard plastic pots with nursery standard medium, pots have no slots. Aside from a little algea no issues. Two Stanhopeas in only sphagnum moss. I have a stack of medium, slotted clear pots ready to go. If I do repot should medium/moss be disinfected/soaked with say...physan20 solution? Any advise greatly appreciated from the pros! Thank you so much.
