  1. Do they make a HPS bulb that works in a MH ballast i am wondering if i can use the ballast to my light over my saltwater fish tank It is a M58 250 watt metal halide ballast if anyone could give me a link that would be great
    that is the bulb you want. it is only 220 watts because hps conversion bulbs are always a little less wattage then mh. i dont know why but thats how it goes. the conversion bulbs are expensive but if its what you want then there you go. also hps conversion bulbs have more blue and green spectrum light then standard hps bulbs. this makes them better for growing under hps throughout the entire grow. peace
