Humidity Trays for Light Stand - Help!

[Becca]

Hi Everyone!

Ok I just bought a wire rack as an addition to my growing space. I've been searching but just can't find exactly what I am looking for. I guess if I have to, I may not be able to use the entire shelf space since I can't seem to find a humidity tray that has the dimensions I need. The shelf of each rack is 48" long x 18 inches wide. It is one of the standard one's you can buy at Home Depot or Lowes. So far I have found a 13.5 x 10.5 humidity tray. I could get 4 of them....but I would have about 6 inches of room with no humidity tray on one side and about 4.5 inches on another side. I also have to keep in mind the 4 metal posts that will be holding the rack together so maybe not having an exact fit would be good? I need the humidity trays so that water won't drip on the T5 lights that are mounted the the rack below them and I would like something that would keep the orchids out of standing water and something that looks nice. I'll probably end up installing a drain tube on whatever I get so I can water the orchids in place and not have to take them to sink any more. Any ideas would be great. This is a link of what I am looking at and I must admit I have found them cheaper elsewhere...just using the link as an example: Single Grate Humidi-Grow Humidity Tray
