Question how often should hps bulbs be replaced? I will start using a mh/bulb for roughly the first 30 days and then switch to the hps. I figure this could extend the life of the bulbs.
Thanks

I used to replace mine yearly when doing 12/12, but I knew lots of guys who would buy used bulbs and were happy. I think it's worth replacing them yearly if you keep your reflectors and glass clean if you have air cooled light.Question how often should hps bulbs be replaced?

Ok was just curious since I will be finishing my second grow, and was contemplating replacing the hps after this coming grow.I used to replace mine yearly when doing 12/12, but I knew lots of guys who would buy used bulbs and were happy.
