No ventilation, warm-n-moist air sitting there...not even close to optimal.
Well, with the cooling thermostat hes talking about, what happens is, you plug the freezer into the thermostat, and the thermostat gets plugged into the power source. Then you set the desired temperature (or range I'm assuming; I think they have an upper and lower bound), and place the thermometer in the freezer. As the heat will rise, the thermostat will give power out, and the freezer will kick on long enough to bring it back to what temperature you have set. When it's back to normal, the thermostat cuts the power to the freezer. People make DIY kegerators out of box freezers and these thermostats for the same purpose. Since keeping the beer at a certain temperature (35 deg. F I think) (and keeping it carbonated with a co2 tank as well), the beer will generally last about a month of being tapped without going bad.

I don't think he'll have the problem you're talking about, because although it will be hot, the freezer is not going to be working overtime since you won't be trying to keep it at temperature near freezing. You'd only be keeping it in the temperature range optimal for marijuana growth. However, he might have the problem you mention, in a sense, because a freezer is not made to keep temperatures that high. So, I don't know if that will affect it or not, but it could. However, I think it would work.
