so after looking for an incubator that would give the kind of visability i want ive decided to make one from a 5 gallon aquarium. im going to cut a peice of plexie glass to fit on the top and put a knob and hinges on it then use a uth with a herp stat or helix. now my question is which thermostat should i go with? and how long is the probe that will go in it? will it fit in the tank? this thing is going in the bed room and i want it to look good.
