Incubating Temperatures

I am incubating at 89. Temp on the Herpstat is set to 89, temp in the egg tub reads 88.9. :gj:

This will be my first year of hatching and I bought my GQF incubator from a reputable breeder who has the incubator set already, I have an accurite therm. with the box on the top shelf and the probe on the bottom shelf. The top shelf is reading at 91 and the bottom shelf with the probe is showing 89. This is incubator temps. not in the tubs. Does this sound OK. Or should I put the probe in a tub?http://img.tapatalk.com/d/13/04/02/vynyhunu.jpg

Put the probe in the tub, isn't that where the eggs will be? That is the temp that matters. I put the whole unit in the tub. Also, I would add some bottles of water in there to help stabilize the temps. It seriously helps.

88-89 55 days no issues here.:gj:

Yes, the eggs will be in the tub. However, consider this scenario: You take the tub out and peek in at your pearly whites. The tub temperature drops from opening, and you trap the cooler air inside with the lid before returning the tub to the incubator. Now, the entire incubator is increasing in temperature until that one tub is back to 89deg. Now, your other tubs have been getting hotter, the water bottles have been getting hotter, and the tub with the probe will now overheat because of all of the ambient increases around it (tub will continue to heat when the tape shuts off because everything else is hotter).

IMO, the two ways to place a stat probe in an incubator are to either place the probe in an EMPTY egg tub (which could still create the microcosm that then creates large temp swings in the rest of the inc), or suspend the probe in the vicinity of your tubs and place a thermoMETER probe in an egg tub as a check (this is how I do it, and get minimal swings). I do agree wholeheartedly with increasing the thermal mass in the incubator with as many water bottles as you can squeeze in there.

This is my first year with eggs and they were just laid a couple weeks ago. My thermostat is set at 89.6 and I get temp swings from 89.2-89.6 inside the egg tub. Hopefully everything goes well.

My incubator has a built in thermostat that regulates the temp in the incubator. I also added the accurite to tell me what the temp is the top shelf shows 91 and the probe is on the bottom shelf showing 90. A pan of water has the humidity at 61% in the incubator and the water in the tubs will increase the humidity there. I also have bottled water on the shelves behind the tubs. I got the incubator from Tim Lane who has incubated many clutches in it. I went ahead and added the water to the substrata and put the accurite inside one tub on top shelf and the probe in the bottom. Then I tweeked it a bit now its holding 89 in both tubs and 99% humidity. I'm so stoked.http://img.tapatalk.com/d/13/04/03/yduvy3ys.jpg

I thought that inc looked familiar, Miles!

Yep Anna I was gonna build one but then I foundout that Tim was getting out so I jumped on it. I was feeling good about the temps 89 in the top and bottom tub with 99 % humidity. Then someone posted that the accurite was only accurate +/- 4 degrees now I don't know. I guess I should check it with my temp gun. I have the unit in the top tub and the probe is in the bottom tub. oh and I bought a light diffuser I'll cut it tomorrow. Now do I just sit the grate on top of the vermic?

Quick question! My egg tub is about a degree cooler than the rest if my bator. Is this normal?
