Conditioning frame

[Eyeman]

Put a frame of plastic queen cups in to condition them for 24 hrs prior to grafting. Weather has turned foul so decided to put of grafting till it improves.
How long can I leave the frame of plastic cups in in before I graft?
It's a queen right breeding hive.

Took the frame of plastic queen cups out yesterday- 4 days after putting them in. The plastic queen cups were as good as new, looked polished inside but no wax present around the rims of the cups. No brace comb.
Plan is to put them back in this Thursay and then graft on Friday.
