Drainage system/Drip tray recommendations

[orion141]

Hi all!

I am trying to figure out the best way to be able to water my orchids without having to take them one by one to the sink. I currently have a 72x48x24" wire shelving unit that hold my orchids (with t5 lights above them). I was thinking of putting a tray below each self of orchids with a drainage home drilled into the corner and flexible tubing inserted into the hole. This would allow me to insert the tubing into some sort of collecting device. Has this worked for any of you? Or are there different, more sensible solutions available?

Also if you used the tray technique where did you buy 48x24" trays from? I am having a hard time locating these online.

Thanks a lot!!
