MH reverse cycle

[tang daddy]

Hey guys was hesitant on getting a chiller now I'm in a hurry to get one the last few days we've had some really warm weather 33c in the day I came home from work yesterday and the tank was at 30c so I shut the lights off and put them on from 9pm to 6am anyone else do this also was thinkin of freezing a couple 2 liters just in case it gets too hot again submerse the ice caps in the sump. That's all I can think of doing until my chiller arrives.
