    Switch HPS bulbs to MH bulbs using same ballast?

    Hi, now I have a Yield Lab Professional Series 120/220v 1000W Double Ended Complete Grow Light Kit, it came with the 1000w HPS light bulb, but can I switch it to a 1000w MH light bulb with this same grow light kit? The question seems stupid but i couldnt find an answer. :confused::confused:
