I'm terrified of HPS. I had one explode in the basement when I wasn't home. It showered my plants with superheated glass, burning them. Fortunately nothing flammable was nearby. Getting water spray on the lamp from a spray bottle or misting system will do the same. And if you touch the lamp you get an instant 3rd degree burn before you even register it's hot.
Mistking
Looking for a misting system? Look no further. Automated misting systems from MistKing are used by multitude of plant enthusiasts and are perfect for Orchids. Systems feature run dry pumps, ZipDrip valve, adjustable black nozzles, per second control! Automatically mist one growing shelf or a greenhouse full of Orchids.
Totally understand. I'm using HPS because I have some....other....plants in there that need it. But honestly it's getting pretty crowded in there so I may end up doing a different tent just for the orchids. If so I will do LED panels. Thanks for all the help
