The bins have no gap at the ground. Works significantly better if you can get a fist below the pallet at the bottom. And the side walls sit on the bottom pallet not on the ground. Wet Scotland here and bin works great as long as I cover before snow comes.
I think stacking helps with mold as long as it's on pallets. I'm in Central Kentucky. Everyone around here used to just have a big wood pile. I want mine stacked. Back in December, a tree service dumped me a big load of Bradford Pear logs. We bucked them and split them right away, and tossed them in the bed of the dump truck. The bed just has low rails and water can run off. We didn't get around to stacking it until June. The wood right on top was perfect, but there was mold on all the layers underneath. It was 1.5-2 cords mounded up on there.
Stacking definitely leads to a cleaner end product. Less mold when stacking. The wood boring insects are another story. I don’t think there is any way to control that. The best way to minimize the sticky paste is to keep the wood dry. A wood shed may be your best option. Good stuff Dave🙏👊🇺🇸
Get your piles out of the shade, kill your grass or get some compacted crushed rock underneath. Make sure you have very good pallets under the whole pile with your outside pallets placed on the bottom ones. Did I mention you need to get your piles out of the shade!!! Piled wood, properly spaced off the ground dries faster than stacked wood and is far easier.
I split and send it up the conveyor and into totes. And then I let it season. I haven’t had any issues with mold. We get a good amount of wind, and so wood tends to season quicker than normal. I know it’s a pain to have to dust that wood off while you’re loading it. Definitely slows down your workflow.
Consider some long stickers to pass through both stacks. The weight of the wood will press down and hold them in place. It will hold your spacing and make the stacks stable.
I live in southern West Virginia,and although I'm not that far away from you we have alot different climate. It rains here quite often and we're having a pretty wet summer. The temperature here seldom gets above 90 and yeah we have high humidity. Im not stacking nearly as much wood as you,but I try to stack from north to south because the prevailing winds blow west to east. I stack my wood on racks about a foot off the ground and three rows deep. I keep each rack about 10 feet apart to tryin aid airflow. Im cuttin alot of red and white oak,hickory,maple and cherry here. Red oak by far takes the longest to season. I only cover my stacks throughout the winter. The only problem I've had with bugs is carpenter ants and it's been minimal. Sorry to hear you're having trouble with bugs,I'm sure it slows your work down. Id say the mildew/mold is just humidity related. Maybe try running your stacks or rows in a different direction or getting more sun to them some how.
By judging from the sun your bins are north to south. If you have mainly east to west wind bins should run with the wind direction because air will flow thru under pallets with a suction affect with the wind blowing past the top and sides pulling air thru the wood. This would explain why you're not getting mold on stacked wood over your loose bins.
My friend, thanks for the comparison... I don't think you answered my last questions: How many customers do you service? Do you currently have enough inventory for the season? If not how much more do you need to feel comfortable? Right Size Raymer Wood!
