Well... You could run a 60-watt incandescent light bulb off of the timer and install it an inch below your HVAC thermostat - that'd be VERY likely to ensure that it is actively cooling at all times that your GR lights are on. But I can already see "one or two" drawbacks to such an idea, lol.
Moving the thermostat into the GR would do the same thing.
Someone in better mental shape than me could probably tell you how to rig up a relay driven from that timer which would cause the sensor in the thermostat to read a few degrees warmer.
