Incubator too hot...
    #532323 - 01/26/02 06:37 PM (22 years, 1 month ago)

I made an incubator out of a foam box, fish tank heater and jar of water... Well, I put my rye grain bags in 4 days ago, these bags were already 3/4 colonized with Gulf Coast spores. I went and bought a little thermometer today just so I could see how the temp was doing in there, after 2 hours I check the thermometer in the incubator and it turned out to be ~95 degrees, is my mycelium dead after being exposed to that for 4 days? any hope?

I think thermal death is like 106 F

Ok, thanks, I'm guessing it'll need a little time to recover from the heat, I don't think it dryed them out which is a good thing.

Thermal death is 106.

You are probably gonna be ok.

If they were jars ....95 degrees in container........97 degrees in the jars.
Good luck!

thanks, they arent in jars, they're in filter patch bags. I hope everything works out... I left them unattended @ 75 degrees for 5 weeks while on vacation, when I came back they were 3/4 colonized, I broke up the mycelium into chunks while still in the bag in hopes to spread around the spawn. How long do you think it will be for them to recover and start growing again?

I had the same exact situation, only problem now is, im fed up with configuring the incubator. Its like 95F on the bottom layer of jars and 70F on the top. I got a blanket and a top. The aquarium heater is going,and i got the supports to keep the extra bin away from touching the water. Now my jars on the bottom look darker and really cooked ! What the hell man. I just cant wait till summer, this winter weather ust fucks up the temp for these poor babies. I have to even plan on setting the temp right ont he terranium too? Fuck! Anyway, Im almost ready to give up on this shit just cause of the temp problem, and this is about my 8th time doing it around. Isn't that grand.

You might need a small fan to circulate the air in your incubator to help even the temperatures out. Of course, this will also help spread any contamination.

A larger space should also help even out the temperatures. Mmmm... thermal transfer... I hated that class. Anyway, if you have hot spots then there is a problem with the layout of your box and heat source. You have a source generating heat. As you get further from the source, the heat transfered begins to decrease. Different mediums (water vs air) also transfer heat at different rates and with different efficiencies. If you want even heating, then you want to have all of your jars in the same medium and at a fairly constant distance from the heat source. The more medium between the sink (what you are heating) and the source (your heater) the more even the heat will be. Some mediums, like copper, transfer heat evenly and well. Others, like steel, do not. Heat also rises (actually, cold air sinks pushing up hot air, but this isn't on a test) so if you stack jars, the ones on top will tend to be warmer than the ones on the bottom, all else being equal. My friend has never used a home built incubator, so my help is limited to theory, not practice or experimentation.

You can pick up a lab incubator fairly cheap on labx, though be careful you watch the size, weight, and shipping costs. They usually have one or two going every few weeks.

That is why you should set up your incubator (or terrarium) at least 1 week before you put anything in it. That way you can monitor temps and other conditions and make corrections before they cost you.
