    Default Which bulbs and when

    I have a digital ballast with the different wattage settings on it as normal, I'm wondering about what bulbs to use at the different stages of the grow, I currently only have a 600w hps maxbright.

    In an ideal world you would have the correct bulb for every setting... but it's not an ideal world...

    A 600w hps will dim to 400w.... but not 250w

    With MH only use the correct wattage bulb

    Ideally, a 600w HPS bulb for 600w setting, 400w bulb for 400w setting, 250w bulb for 250w setting... if your ballast goes below 250w then bulbs that match the wattage.

    With respect I don't think your understanding what I'm asking, I'm wanting to know if there is any sequence of different types of bulb. i.e: 250 cfl seedling, then mh, then hps if you catch my drift or just 250 cfl then 600hps

    Ah! You mean which bulb for the differing stages of growth?

    No idea I grow autos, so it's full power from the start for me
