thanks for the help. i am building a unit after looking at a few on here. i chose to go a different route though. i found two plastic storage containers that fit inside one another and "lock" in place. the top container is pretty much half as tall as the bottom which allows for a cavity below to hold the water and pump. ran some pvc in a way that looks like a blocked figure 8 (only way i can describe it) in the upper container and connected it to the pump. drilled holes and threaded in the misters to the pvc. finally drilled small holes in the bottom of the upper container to allow excess water to drain back into resevoir. only thing left is to cut holes in the lid for the plants and find a way to make the containers light proof (they are clear containers, all they had of that kind) probably gonna paint it black but not sure. i will post pics tonight when i get home.
