I really hope they aren't screwing with me on the arrival time. I want to chop my 3x3 tent. Ideally this weekend. If the fridge gets here tomorrow, then I can assemble it tomorrow night and run it for a couple days to function test it.

Running fit for a few days to get it to the right temp/humidity really helped when I loaded the first time from getting any wild swings. But I didn't wait and I put a small amount it for test. I'd suggest some hanging time to reduce a lot of the moisture then load it.

@Hook Daddy did you mount your dehumidifier inside the fridge or just set it in there?

The opening for the heat sink that originally blows out the top of the dehumidifier, do you still point that up? Does that air flow cause the buds immediately over it to get crispy at all?

For the most part, it seems to be working. Sometimes I have witnessed that the fan has a hard time getting started. I'm guessing that a connection may have been faulty. I have just taped the connections so far so it could definitely be that. I have ordered from the free Amazon stuff some 2 pin pigtails that I will be soldering in so I can make the dehumidifier removable for cleaning or maintenance purposes. When it's running though, it definitely seems to be working. I had the inkbird set at 60% and the trigger setting at 69%. Looking at the graph, it fluctuated between 58 and 63 so I'm kinda wondering if that's not just the fridge holding it and the dehumidifier wasn't kicking on at all? Either way, the hard stuff is done and I'll be working out the bugs and getting her all dialed in. Taking the bottom grate into work to cut the corner out for the dehumidifier. Also taking the dehumidifier in to trim the top part of the casing off to clear the 2nd shelf.

I soldered and used heat shrink over them. Everytime I do that it reminds me I need a soldering station :roll: oh well I'll remember again next time I solder.

Sorry, been a wild couple weeks at work, anyhow I did not mount the dehumidifier just set it so the pointed fins are in the drain channel. I have not had a problem with air flow causing drier buds in places, but the coolers fans also run, and there’s a fair amount of humidity in there to go around.

Awesome, thank you. Just wrapped up getting the shelves zip tied. Everything worked perfect, wrapped it up, and the dehumidifier was having a problem starting again. Swapped the cube for a higher amperage one and it seems to be working now. Gonna clip a couple branches and toss em in there overnight.

Set the rh at 61% with a 5% trigger. It runs up to about 71% and then starts dropping. That's with only 5 sticks. Definitely going to do the hang dry for a day or so before loading this guy up this weekend.

It ran great all night. This is what I'm seeing this morning. Dehumidifier runs until 61%, it shuts off, rh continues to drop to about 60.5%, rh starts climbing, Dehumidifier turns back on at 66%, rh keeps climbing to about 66.5%, then it starts dropping. Repeat. The climb from 60.5 up to 66.5 took about 5 minutes this morning.

Already a great improvement from climbing up over 71% in 2-3 minutes last night. I'm excited to see what it is doing tonight.
