Hello 420ers.
I just got a 400w Metal Halide fixture and have been running it for a while now with great results compared to former CF's. I've heard about fires caused when these bulbs burn out, Has anybody had any experiences or warnings?
Now I've got some plants vegging under the MH's but I've taken to just leaving them on while I'm home. 12 hours typically then I leave a 150W blue CF on them for the other 12. Whatev. Here's my question for the gurus.
Does the dark cycle on vegging plants (say on a 16-8 cycle) have to be completely dark like it has to when flowering? Will random ambient light during the OFF cycle cause the risk of hermies in vegging plants?
Thanks in advance for any help anyone can offer.
