Humidity trays on how to set it up and what i have

[pauldog28504]

People say that you should put your Orchids on a humidity tray. i am just getting into Orchids and do not want to spend a lot of money just yet on them. i bought some cookie sheets that are the throw away type and the pea gravel b/c i have heard that the pea gravel is good to use. Do I just put the plants on the gravel and let them sit or do i need to drain the water out daily. My orchids are in a plastic pot and they have a clay pot i can sit them in but dont think it would be a good idea to leave them in the clay pot b/c of to much water. Any suggestions on how to set this up.

Thanks a bunch
