Humidity trays
 

Metal or plastic?
I need some opinions on making a choice between the two. I'd also like to know if anybody has a good source for these. I really don't want to spend a fortune on these and for the area I have, I'll need to get a few.
Thanks in advance :)

Plastic, no rusting
Metal, no breaking. Argg...
Plastic don't weigh as much.
Some metal trays wont rust i think

Id go with plastic. I didn't even know they sold metal trays

Plastic is what I've thought I go with, but through my online search, I've seen a few metal so I thought I'd better get some opinions. I've even seen some that are hammered copper, specifically orchid humidity trays. They are stunning but awfully expensive.

wouldnt they rust and then turn bright green?

Probably, which is another reason I wouldn't get them, but the pictures with blooming 'chids in them sure make them pretty. :)

I did come up with an inexpensive tray, though. I've searched the net for ones with a decent price but they were way more than I wanted to spend. I have one rack with 2 shelves that are 33x17 and one that is
33 x 8. It would cost a fortune getting enough of the smaller sized trays I've seen. I went out on a mission today and found them. Where else but...Walmart! I got Rubbermaid drawer dividers. They are 16 x 6 and have a small lip along one long edge to hook onto the next one. It'll take 5 each for the big shelves and 2 for the small one. They were only $2.47 each, so I got them really cheap! :) Next step is grids to go over the top, think hubby's gonna make them.

Oh yes, I remember I saw that website from when I was searching for humidity trays. I quickly passed the website after seeing that 1) they were expensive 2)there's no drip tray/grid on top.

I had an idea on how you could make a grid for the plastic trays relatively easily. take some this stuff, cut to size with a utility knife, and then use a big stapler to tack it onto the plastic tray. you could stretch it taut across the top or maybe fold the edges down a little and set it in a bit. it might need a few little supports in the center for the bigger sizes though.

Hi Scott, nothing specific came up with that link, just a full page of HD stuff. I was thinking the wire racks that they're now using in closet systems. We also thought of vinyl lattice board but I think the holes would have to be larger than that.
