It's a simple concept. Their seeds need to be kept at a set cool temperature. If you already have a walk in fridge that maintains a set temperature, adjusting an incubator by a few degrees is very easy. If you have it outside or in a greenhouse you are dealing with fluctuating temperatures and need to be able to both cool and heat to maintain a temperature setpoint as well varying energy requirements for both. The fridge system offers much more control and easier fine tuning.
