I would say no holes.Kiln 3.2 x 4 x 6 ft with 250 W terrarium lamp and humidifier. I think about two holes size of ice hockey puck sufficient? One above the bottom, the other under the roof both in the middle of the longer wall. Do you think it is sufficient?

sorry, I was not able to rotate the picture...
Thank you for info. Sorry, I am mixing two things, kiln and flue curing shed. English doesn't make it easier for me.My kiln was 3'x4'x3' with no holes. My flue curing shed was 8'x4'x8' with two 1" holes, one of which was vented with a small exhaust fan that only turned on above a certain humidity level.
Thank you Bob. Now I get it. The reason why I was confused by these terms is maybe this: The kiln translates to my language as drying room.Different tasks:
Color-curing and drying usually require ventilation. Kilning requires thermal insulation and a good closure seal, to limit energy cost, as well as to reach the required temperature (and retain moisture, unless the moist, color-cured leaf is sealed in separate containers--jars, etc.).
- color-curing (going from green leaf to yellow to brown) before the leaf ever dries
- finish drying of color-cured leaf (usually drying the stems)
- fermenting leaf that has fully color-cured [KILNING]
Funny how "will work for beer" seems universalThank you all for your help, ideas and explanations. The kiln is now being tested, I plugged the electricity in this afternoon and temperature slowly grows (now 45 C, 113 F), humidity is moving between 68% and 72 %, humidity controller is set up to 70%. Seems that this thing could work. It took few hours to warm it up, hope that it will not be the same after every door openning and refilling humidifier.
To be truthful with you, it was not me, who built it. My good friend was the constructor. I was just bringing him beers and helping here and there. It costed about 300 $ on material & accessories and some drinks.

I can't wait to hang some tobacco in.
They don't need sealing? Have you tested them in an oven to be sure that no off gassing occured? A test piece Taken to your working temperature will do it. Check my kiln build thread, and you will see what to do. I'd hate to see a kiln full of tainted, unusable Tobacco.Inside walls are made of gypsum (drywall).
My first two years air curing were done in what was my smoking room in the garage. It was drywalled. Mold or mildew grew on the lower part of the walls, much like it would on the ceiling above a shower.Just curious, do you think the humidity in the kiln will cause any issues with the drywall? It seems like it should be ok as long as it's not getting dripping wet.
I don't know yet. Hope it will be ok. In the beginning I described to my friend, who built it, that there will be high humidity and temperature. He is works foreman by profession, restores old buildings. I spoke with him by phone today, he said these drywall desks were more expensive with better resistance to water.Just curious, do you think the humidity in the kiln will cause any issues with the drywall?

Sounds scary. The only thing I can do is to run it without humidifier for two or three days when the tobacco is finished.My first two years air curing were done in what was my smoking room in the garage.
