I was thinking about getting a conversion bulb for my 400watt HPS system. I can get a MH conversion bulb for like $45. Has anyone used these before? I never hear anyone talk about these things but I always see them at the hydro store. Is it worth it to spend the cash or should I just use HPS all the way. I have had good results. I use a 125watt Feliz CFL for seedlings then after a few weeks put them under HPS.
