Automatic watering for orchids?

[Fairorchids]

If you have shade spot outdoors, place them there (in trays or baskets, so they won't fall over). At Home Depot you can get a battery powered programmable water control (about $30), which you put on the spigot. Then connect a hose and a small sprinkler placed by the plants. Remember to open the spigot.

If you give them 10 min every 2 or 3 days, they should be fine for 3 weeks.
