    Hi,
    I've been trying to find out what the following letters mean on growlamps. You get them on metal halide bulbs, it either says
    HPI-T
    or
    BLV HIT

    Does anyone know what they mean or what the difference is ?
    many thanks

    I did google it before posting to the forum. I've seen both types marketed under various brands. You can buy a 600W MH HPI-T for £50 or a 600W MH BLV HIT for £25. I guess if they are both the same and its only a difference of manufacturer (rather than light output or spectrum) I'll go for the cheap option.
    cheers

    i have the HPI-T bulb. good for vegging. not flowering. its a safe choice.

    no idea about the other one. if it is an "aquarium" light it might be good.
    it would have alot more UV output. Marine animals, reptiles etc need UVs and use it for making some vitamin or something. anyway, pot produces more resin to shield itself from UVs. id use it in flowering, IF thats what it is.
