    Light distance question

    Hi Growers,

    Viparspectra’s suggested light distance during flower is 18” for their XS2000 (dimmable 240 watt led qb).

    Actual distance with my two plants is 15-16”. In week 7 now with no symptoms of light burn.

    For what it’s worth, Vipar’s high PPFD specs in a 2x4’ tent are:
    1057 umol/m/s @18”
    1469 umol/m/s @14”
    1794 umol/m/s @12”

    Will my colas be okay at 15” at 100% power? If not, I can add 1-2” of clearance or reduce power level. Otherwise I’ll let it ride as is.
    Peace!

    You see what we don't Cheeba i did'nt have mine that close with 100% i use 75% at 20" eased my mind and they came out fine but your close up to your grow. Just when you see the slightest burn on those white hair you'll know it's not normal ripening??

      SoOrbudgal how can you tell the difference between white pistils turning brown at the tips because of normal maturation as opposed to burn from too much light?

    If you really want to know how close you can get with your light I'm afraid you'll have to singe some colas!
