When a Metal Halide bulb fails

[Oscarman]

Just recently during a brief vacation the outer glass tube on my 1000W MH light failed (exploded would be a good term) due to water being sprayed on it.

When the outer glass tube fails the area under and around the light is dosed with a high level of UV. Fortunately the person caring for my plants was not injured.

Many of the plants in my grow area received instant sunburn. Many plants show no ill affects at all, despite being right beside one that was injured! Here are a few pics. Hardest hit were compots of Phal. bellina with approx 80% leaf loss. Around the room leaves are dropping almost daily. In several of the pictures you can see the bright green growth that has occurred since the burn. Promising signs.
