Thanks again for the advice, everyone! Once again the Lumber Jocks are swooping in to save the day.

@Wildwood – Thank you for the reference material. Check out the stickers I made in my first forum post and let me know if you think those will work. I was concerned with warping and sticker stain. So, I planned them all to the same thickness and cut the grove to help airflow and reduce touching surfaces. I think that’s all good, but wonder the thickness planning cut them down to only 1/2”. Is that enough for proper air flow? I’m hoping to make it enough by including fans and spacing each column a few inches apart.

@Randy_ATX – Right. I didn’t realize it would happen so quickly and though I had enough air flow. Apparently not. I’ve cranked up the fan, added a second one and opened my garage door a couple inches to hopefully help with all that. I’m hoping it’s not too late. I think it will be OK from the feedback I’m getting.

@fuigb - First thing I did, my friend! This is putting me in gear to just do that kiln. I just ordered the stuff to do it this week. By the way, I did seal my ends a while back. Not with anything recommended, but I had some oil based Kilz primer that I’m hoping works better than nothing. So far so good. I’ve got some weight on it as well.

@avsmusic1 - The very top boards that contacted the plywood weren’t molded, surprisingly. But the plywood is, unfortunately. The top middle to top part of the stack seemed to be hit the worst. How much WO did you have in your garage and how did you stack it? did you leave your door or window(s) open? I’m wondering if the lack of fresh air hurt me. The fan might just be moving around wet air.

@ArtMann - Yeah, I’m not so worried about the effects of the mold on the wood aesthetics since my main project for this stuff is for a new large benchtop. I’d like it to look nice, but not necessary. I’m mainly concerned with it being compromised and unusable. Also, I’d like to learn how to do this correctly, so I don’t have these issues again in the future. I plan on doing this a lot more over the course of my life and after this round, I’m going to care about the aesthetics a lot more.

@tomsteve - It’s tough to say. Certainly less than half. The ones affected were pretty bad, but there were several that didn’t have anything on them. But just because I couldn’t see it (yet) doesn’t mean it isn’t there. The boards most visibly affected by the mold were sort of hit or miss. The bottom actually seemed to have less mold if anything. I’m guessing that’s because my box fan was on the floor, giving them better airflow. I’ll definitely lay down some plastic when I restack again this week! I’m assuming that generic Harbor freight blue tarp is good enough or do I need something special?

@everyone -
To wrap things up, here’s what I’m getting from you all and my internet research:
I’m thinking on my next break from work, I’ll scrub the mold off with either alcohol, vinegar, or maybe a bleach-detergent solution (apparently, bleach alone can’t penetrate the pores to completely kill off the mold). I went ahead and ordered a small dehumidifier and moisture meter that should get to me on Tuesday. I’m thinking I’m going to try the simple dry kiln under a sealed tarp with the dehumidifier (and maybe a space heater) someone mentioned to me recently. I’ll closely monitor and do some more research on what settings to use to keep from drying too quickly. In the meantime, I now have 2 fans on high blowing on the stack from about 8 feet away with my garage door cracked open a couple inches. I’m wondering if one of my problems was having the door closed. I had some air movement with the fan before, but no regular source of fresh air to replace the increasingly humid air in the garage.

Thanks a lot for the help again. Hopefully, this will get me on my way to posting projects on here soon instead of just a bunch of questions! Of course, any further input or advice on my plans is always appreciated.
