Your flexwatt should be heating more than that. I think either you've lost a connection to the flexwatt or your herpstat isn't putting out any power. To test this simply unplug your flexwatt from the herpstat and plug the flexwatt directly into an extension cord. You should be able to feel the flexwatt start to warm up when you hold your hand on it. If it still isn't warm, you're not getting power to the flexwatt and need to re-check your connections. To test the herpstat, if you have a lamp around and a regular old incandescent light bulb, plug it into the herpstat while you've got the red indicator showing it's heating. If the lamp doesn't light, your herpstat isn't putting out power. And yes, you'll want to get the fan before you set up multiple shelves with eggs. You may or may not need more flexwatt once the fan, flexwatt, and herpstat are all working.
