We don't have air con, we have doors and windows :)

I never thought of the ice cubes and I am worried about the plants with the lights out. It will be OK when I'm here which is for 40 days out of 42 but we actually get 2 days off work every 6 weeks and go away (If we stay here, we might as well milk and save money).

Our relief milkers are quite capable but they won't be here in the hottest part of the day. My husband is never going to accept getting air con for the fish :) (I actually don't want it myself b/c it's much harder to go out and work in 35°C heat after sitting in a/c than to be gradually warmed up all day)

Maybe I can set up and esky type thing with ice water to drip in all day and the relief milkers could siphon some water backout and restock it?????????

Well I've got plenty of time to work it out but if anyone hears of anything or has some brilliant ideas before next Dec/January, let me know.
