I finished my freezer kiln today. It has a temperature controller that turns on and off 2 40 watt bulbs to regulate the temp i set. It has a humidity controller that turns off and on a fan based on a humidity range i set.

Now i need a procedure to set each of these when i load it and as the wood is drying. Any thoughts on how best to maximize the efficiency of this kiln?

Thanks
 
Remember different woods dry differently....cherry very prone to cracking....need to do load of cherry by themself.....other woods can be mixed....take notes in each load....wood...temp....duration...etc
 
You will have to experiment a bit.

Keep track of the water coming out.

Removing water too fast will dry the wood too fast make it worse than sitting out in the open.
Set the temp for 70-80
Start off with an RH of 90 and gradually move it down to 40.
If little no water is comes out in a day, lower the
RH by 10.

Humidity will take care of itself as long as you do not promote too much air exchange, ie. manage inlet and outlet size. Control the temperature, starting at near ambient and gradually increasing. See my comments and chart in the other kiln thread that is currently coming up as well.
