Ended up adding wider shelves with a lip, think it helps a lot. Now I just need to figure out where to put a tub of water. Think it will have to go below the shelves. I also made it to where my power strip and timer are hanging on the wall. The power strip wasn’t staying that well with the wall hooks it has so I had to add some electrical tape.Looks good!
I'd consider extending the shelves and adding a lip.
It would definitely be better to have the intake vent separated from the outlet - ideally low and at the opposite end of the room.
If you can have the outlet venting from above the trays - maybe by using a bit of dryer venting tube - that would be best.
