first thanks for the great thread, idea, etc. i built one of these and love the concept. i am having an issue where the RH in mine seems inconsistent between top and bottom racks, and even front to back of the unit. i have my RH set to 70, and the bottom rack will be 70, but the top rack will be 89, as indicated by the small hygrometers ive put on the different racks. racks in the middle vary between those two values. ive noticed that even front to back the humidity swing is very large.
i do have silicon mats on these racks, im thinking that there is not enough air flow to mix the humidity well, i have ordered some silicon mesh to replace and im hoping that will help.
my question is this, i did put my inkbird humidity sensor on the back wall near the fan. is that still the right place, or does it make more sense to locate it on the top or side somewhere. that seems like it would be the least humid spot since that's where air is being pulled out, but im not sure. has anyone else had this issue and resolved? i really want to read all 72 pages but that will take a while and im worried about mold in the meantime. any thoughts? thanks,

You are probably on the right track replacing the silicon mats if they don’t allow free air flow, that would certainly cause the symptoms. As the buds dry overall the rh change front to back and top to bottom should minimize, meaning once you get rh down into the low 60s and the buds start to dry inside some, they are releasing less moisture and overall the cooler evens out. An extra small fan may help if you still have a problem, but I would replace the mats first, that will likely be the fix.

ok this worked. put them in last night, let it all settle down and checked this afternoon. all racks were within a few points of each other lowest 67 and highest 74 when set at 68. still not perfect but alot better than 20-25 points off from top to bottom. i used bbq grill nonstick mesh as mentioned somewhere in this thread.
