#1: I got lazy and left this way too late, but if I don't get it finished I can hatch in my incubator. #2: How much airflow is too much airflow? Can you take a peek at a 30-some second youtube video ? Ignore the temperature, if you can see it, and ignore the humidity setup. I'm trying to a) get my heat sinks up to temperature, and b) make sure I don't have too much airflow going over where eggs will be hatching before I finetune temperature and humidity. I figure if I have to change the fan speed, then temperature and humidity will both change, so ... fan first. It's a $6 4" fan from WallyWorld, and it's one speed ... but I have a dimmer available, and my lamp can live without it for a few days if I need to slow down the breeze in there. I made that little wire arch and stapled on a little flag of gauze material so you can see how much the air is moving - that will be coming out, too, once it's right. That's jelly jars of water around the bottom, supporting the hardware cloth. I am planning to put the soft anti-skid shelf-liner over the hardware cloth before I get much further in this process. I have two of the small 40watt bulbs in a splitter in the end - because I'm paranoid that a bulb will burn out, and that way at least one will maybe stay burning. And I put a couple more holes in my water heater thermostat, to encourage more airflow in there and hopefully a more steady temperature, and the thermostat is attached to a 4" metal outlet box for an additional heat sink, also hoping to encourage a steadier temperature in the hatcher. Critiques? Turn down the fan?
