Oven Tek revisited
    #3861209 - 03/03/05 02:54 AM (19 years, 30 days ago)

I had a pondering today..

I was looking through old threads here and in several other communities learning about sterile environments. I decided and learned how to make my first pos pressure glovebox, and poked around at other methods. One that stood out to me was one "oven tek" where the materials used were placed at the opening of a hot oven, and "upward currents kept the contams out of the jars". I along, with anyone of any sense thought it was a silly idea, as the contams would just back eddy into the jars and swirl around, filling everything with all but nice growth. I then proceeded to read a bunch of arguments between sensible people like myself and trial and error types who were reporting success with this "tek".

After some thought and much smoking of marijuana I came to a theory. I think the idea of an upward current of warm air has nothing at all to do with the reason why this "bogus" tek has a very high reported success rate. After some study of convection ovens I got to thinking about the amount of air and the rate at which air circulates through an oven, relative to the room. I found that approximately 90% of the air in an average kitchen can be reasonably thought to have passed through a running oven in 4 hours. Virtually all air in the oven approaches very high, unlivable (even for contams) temperatures before its time in the oven is complete, passing by hot elements and being charged with heat to rise out of the oven vent. Given this, an oven can be said to kill virtually all of the bugs in 90% of an average sized kitchen. This is an average kill rate in the entire room. Throw on the added protection of working near the "clean air" outlet of your oven, and you've got yourself a tek :smile:

This brings up the question of how this tek would be performed if adapted for the "other" theory about why it works. I would suggest, as opening of the oven will bring down temperature and thus kill rate, the best way to approach this method would be to run the oven for several hours at a high temperature, and then work in the natural outflow of the oven vent, rather than disturbing the airflow of the room by opening the oven. One could perhaps even attach hose to the outflow on their oven and direct the clean air for a custom area effect. The possibilities with this are plentiful, with the discovery of the actual value behind this tek.

What do you think? I could just be high as shit, but I think theres something to this, and it should be properly tested and documented.

i told you about 20 times in #cultivation
to forget about it, but well, guess your hard to turn down.

i sitll wish you good luck, just always keep this in mind:


uhm yeah and in relation to my ionizer anno said something alike
some time back, it was like "it depends on the environment one has,
then maybe even bogus teks as the oven tek may work,
if the environment is super clean"

:frown: thats the third time you showed me that, and this is the third time I will ask you to try to understand what I'm saying, perhaps reread my words, and realize that I'm talking about an area affecting air sterilizer, rather than some current based hokey hail mary attempt at sterility.

forgetting the picture. there is also the fact that non filtered air is drawn over your project on it's way into the oven.

the oven vent is a better idea, but that air is VERY hot.
glad too see you have the old noodle working. good luck

That " Rush of air " you get from the oven, i beleive is from the moisture in the air being heated by the oven, the heat makes the air/moisture expand and creates a flow. < stoner observation mostly.

But, stick with what works, most people who do the oven " tek " and have success could probably just as easily work on their kitchen counters with problems.

I know i would'nt put nothin sterile in MY oven !! LOL...

the marijuana has clouded your thinking, convection ovens circulate the air
within the oven, it doesnt pull room air in and expel it back after heating it
although ovens are not air tight, there is no real circulation in and out of
the oven, simply a little heated/expanded air that leaves it and a small amount
that enters

view the picture that Anno did for the oven tek, look at the direction that the
smoke is traveling, most goes up over the lip of the jar but you'll also notice
that there is a small amount thats dropping into the jar, the heat creats a high
pressure area thats trying to stableize its self, it pushes smoke and contams
into the lower pressure area (the jar) which has cooler more condensed air.

Virtually all air in the oven approaches very high, unlivable (even for contams) temperatures before its time in the oven is complete, passing by hot elements and being charged with heat to rise out of the oven vent.

Throw on the added protection of working near the "clean air" outlet of your oven, and you've got yourself a tek :smile:




where is this vent located, I've taken apart and cleaned many ovens, none of
which have venting that goes from the interior compartment with the heating
elements to the outside room area, there are thermal expansion vents to keep
the insulated areas from exploding from pressure buildup but these are seperate
from the oven its self it's a part of the ovens insulation system thats designed
to prevent superheating your house

Quote:

This brings up the question of how this tek would be performed if adapted for the "other" theory about why it works. I would suggest, as opening of the oven will bring down temperature and thus kill rate, the best way to approach this method would be to run the oven for several hours at a high temperature, and then work in the natural outflow of the oven vent, rather than disturbing the airflow of the room by opening the oven.




you realize that running your oven for several hours is going ot increase the
ambient room temps by at least 20 degrees and also waste a great deal of
electricity, it's also not foing ot be as effective as a still air glove box
or better yet, a flow hood, the only effective 'oven tek I could possibly see
is the 'climb in the oven, close the door and work at 450F for an hour. after that, you should be done and no contamination issues, well maybe not done per
say but at least medium rare.

Quote:

What do you think? I could just be high as shit, but I think theres something to this, and it should be properly tested and documented.




I think your right, your just high, try taking your oven apart sometime and see
how its designed, I'll post some pics tonight of mine and how it's put together,
there's no air exchanger

All convection ovens intake and exhaust air. I just came back from my kitchen, where my perfectly normal oven is doing it just now. Perhaps if you reread your oven's manual, looking at the list of parts you would see something usually referred to as a "steam vent" or "exhaust vent". The exchange of air within the oven is required, to prevent steam buildup which would ruin your food.

Glove Box ....hands down beats "oven tek", unless you could get inside the oven & close the door, along with the materials you plan to work with. Bit crowded....LOL.

All the electricity it will cost running the oven for 4 hours at a time will easily cost more then a glove box, even including a flowhood. That is assuming the reasoning is even correct, which I dont.

Agar has plans to build a rediculously huge flowhood for like 150 bucks.

Cheap glovebox though..4 dollar rubbermaid bin, 4 dollar gloves, two holes in the side and you have a glovebox that will do you better/just as good as the oven tek. There are others, better built for 10-50 bucks..Anno or Pris1 had a whole shit load of nice ones meant for opening mail during the whole terrorisim thing, but since anthrax is no longer an issue, they went cheap..look around they're all over.

Running your oven for 4 hours if you need a clean room to work once or twice a week will get expensive fast. Not sure how much your electric bill is, but mines high. Not to mention I have to watch consumption so that my HPS lights go unnoticed.

More like $250..... &....... It is not all that " rediculously" big. Big sucker is nice to work in. Built it big enough I could but AA 941 inside it before opening it.


It is a nice thing to PC large grain/spawn filter/patch bags - UNSEALED. Allow to cool in PC, open under flowhood & G2G.... then impulse seal bags. Almost ZERO contam rate.

It amazes me how much trouble we see people going through to avoid cutting 2 arm sized holes in a small clear rubbermaid container. Just put some latex gloves on and stick ur arms through the holes. That will give a tremendous success rate. If you seal it up totally, so much the better, but a simple rubbermaid with two holes cut will give excellent results. I carry one and a bag of latex gloves in my jeep at all times when in the mountains. I'm always cloning wild fruits and that simple thing is what I use.

I must say, the glove box is so cheap.... the only thing better is the flow hood, which is a lot harder to make and costs tons more... but the flow hood is all the easier and more pleasureful to work out of.

I think sir, you are confused on the definition of rediculously huge, because both your PC and that flowhood are rediculous man :smile:

Ok, 250...but still for a huge flowhood. Like said though, simple glovebox is cheap, easy and will do you better then waiting 4 hours heating up your house wasting electricity to do some work...
