1 dehumidifier
the hardest part was getting the drains pitched correctly And fabricating the water catch drain pans
I used 10 1” x10’ Sheetrock corners to crazy glue and zip tie stainless steel 1/4” mesh for 12 shelves.
I also used 2 12v fans to circulate the air inside
and lastly the rubber gasket to seal off the door
used racket straps to keep the door shut tight, but honestly they are annoying and useless. The door seal fine without them.
That’s most of the things u need to get started
