heat up your oven to lets say, 250 degrees, pull out the bottom most rack and set your jars on it, now do your thing, the upflow of heat the the oven will produce will keep contams above your workspace (the bottom rack, pulled out) for up to 15 minutes!

I did this tek on my first batch because it seemed like the easiest to do and only 1 of 10 jars stared colonizing. My guess is that the heat killed the spores. You can try it, but make sure you keep your syringe away from the heat in between inoculations.

The Captain's Oven Tek is great. To get over the potential overheating problem, here's what some people do:
1. Get organized. You want to work kind of quickly and very smoothly.
2. Turn your oven on to somewhere between ''Warm'' and 200 degrees. (250 degrees is WAY too hot IMO). Make sure it's on ''Bake'' and not ''Broil.'' Every oven varies temp-wise. The warmer it is normally, the closer you're gonna want to be toward Warm. If you hold the corner of a piece of lens tissue - or a 1/2 piece of toilet paper - in your grasp over where you work and it tries to float up and away, it's warm enough. Don't let go!
3. Use the upper rack - the one farthest from the heat source. You don't need all the heat, but you do need an upward draft caused by the heat. Try to work as close to the end of the rack without spilling crap.
4. Keep your foil-covered jars on a counter nearby and not on the rack. Move 1 or 2 jars to the rack at a time. Inoculate them and then move them back off the rack and away from the heat.
5. It's not a laminar flow hood - you definitely must sterilize the needle between inoculations.------------------

By sterylize between each jar do you mean you must get the needle red hot and then wait for it to cool down between each jar? also does anyone know a cheap way to make a little alcohol burner? i've heard that regular lighters cause to much black residue on the needle, is that true? thanks

I was wondeirng the same thing. if the needle does need to be cooled does that mean you just have to get it red hot and then wait for it to cool down to normal between each innoculation? thatnks

yes!! the needle needs to be cool. any spores that go through a hot needle are instantly killed. it doesn't necessarily need to be red hot. i dip it in alcohol and light it, then let it burn out. i may repeat if it didn't burn very long. then just squirt some solution through the needle, it'll cool it off.Link ------------------

this might sound like a dumb question but since the whole syringe except for the actual needle is plastic wouldn't having a flame across the whole needle melt some of the plastic? also how can you tell when the needle has cooled down enough? do you just guess or what? thanks

What about using a torch lighter to get the needle red-hot, and then dipping it in a cup of alcohol to cool down? Sound like a decent plan? I'd rather not just squirt out a little spore solution to cool it down; might as well conserve the solution if possible.c

The oven should only be about 150 degrees, more heat is counterproductive. Put a cookie sheet on the middle or top oven rack. You can keep your syringe on a alchohol soaked paper towel on the opened oven door, along with a soaked cotton ball to swab your needle with after a jar or two. Don't bother with holes in the lids or a verm or other layer, just squirt your spore solution on top and down the sides of jar a bit. The needle stays clean since it never touches the substrate. Much quicker & easier. loosen the lids when the jar is about 1/2 colonized. Anything that finds its way in seems to land on the top half (which is already colonized & hence impervious) and not get down toward the bottom of the jar. Furthermore, you can incubate your jars above the oven if you have a cupboard up there.
