potting idea, need advice

[bryce.martin23]

I was thinking about trying to make a pot that creates humidity and water on its own. I dont know if this will work and need advice to either ditch the project before even starting or give it a shot. What i was planning on doing is using a real nice concrete pot that I have been wanting to use for something for a long time. In this pot I was going to make a stand out of pvc to line the bottom half of the pot and fill the bottom of the pot with rock, keep in mind the pot dosnt have any drainage holes. Then above these rocks I was going to make a flat pvc tray and line it with screen door mesh. On top of the mesh I would use a bark mix to plant the orchids. What I was thinking is if you filled the bottom portion of the rocks up with water just below the point where the roots can get wet will this be able to keep the humidity up and ultimatly be less matinence with watering since the humidity is under the plant, and also was wondering how fertilizer buildup might effect the plant since the solids would build up in the bottom. Please let me know if this is a stupid idea or somthing worth trying. thanks
