Although I don't think that 3 years air drying is too long, a month is definitely too short.
I have in the past cut and dried my own lumber. I've got a dwindeling pile of walnut and a bit of ash currently on stacks drying.
I dry outside on cinder blocks on the North East side of my house that receives sunlight most of the day and a constant breeze. I have stickers ever 20 inches or so and always one within inches of the fresh sealed ends. I do my very best when stacking to do it right the first time. I have a piece of plywood I glued a cut of tarp to for the top of the stack that overhangs about 6 inches on each side. Once it's stacked, I normally downstack and rearrange ever 4 or 5 months(the true purpose of this is usually to clear out mice nests that have been tucked in and driving the dogs crazy.) I take this opportunity to get the bottom guys on top and top boards more down the stack.
With this setup, I've both had success and failures. I built my bench from ass that dried in a little over a year, and I've still got some walnut at 6/4 that just isn't ready yet. It's definitely not a fast process and pushing it will only lead to headaches.
Feel free to pm if you have any questions.
