AH HA! The MESH THING.
That's my wind baffle.
The fan was putting out too much wind even on low setting and the girls were in a freakin mosh pit.
The screen about a foot away breaks up the wind into a calm breeze.
I was having to tilt the fan side to side each day and bank it off the walls.
No more problem with the wind baffle...
I don't have enough room in there but to hang everything (including scrubber) from the ceiling.
But the water wand; that thing is GREAT. No crawling around tearing up plants or over-watering.
Me likey long time.
