What is the average life of a 150watt hps?Can i use them till they blow or should they be changed after a certain amount of grows

Yep, That! I change mine every two grows now, sucks but they pay for themselves with their high output.

ill be honest with you, i haven't changed my bulbs in about two years, 12 hours a day 365 days a year, 8,000 plus hours..and haven't noticed any difference in the size or quality of my flowers... i honestly think people change their bulbs to often

I have proved this over and over again to myself, fresh bulbs are the most effective yield improver. Bulbs can give the same yield after a year, but most of the time they decline. Two crops and out for me.

I don't change mine until my light meter says they aren't as bright.
