Grow Mediums Ice probe + 5 gal cooler+ thermostat= end of heat problem

[steelcap956]

I built one. Gutted a wine bottle chiller and added to fans to a large heat sink and sandwiched the TEC between a small heatsink off a blower motor resistor for a Ford. Cut a hole for the cold side heatsink to go thri the Aerogarden Rez and marine epoxy for a seal. I used the control panel of the wine chiller as well but I got a digital temp control box in route from amazAm already. It costed me under $30 for everything
