    Any small sticker still on the ballast? it usually will tell you the bulbs it takes, mine is magnetic 400w and accepts both bulbs
    I hate using the Mh as I keeps me plants looking like cabbages with no chance of tying down the main branch

    One way to find out, put an MH in there, and if it blows, you know it only takes HPS. lol

    Not much . Only higher leccy bills . MH is a hog on electricity for same wattage but less output .

    Invisible sun or HLG led lamps .

    Ive always use only dual spectrum HPS(sunmaster or eye hortilux) and slowly retrofotting to LED 3000k for all my 4 grooms a 320w ish320 is worth 600w . Just keep the heat down with hps and they will.stretch less .
