    Default QB distance with autos

    Hello and good day my dudes
    Gonna try autos for the first time in a couple of weeks and a wee bit confused about the lighting distance
    I always red that autos require maximum light
    It's a bit of unclear to me, should I blast them at full capacity of my hlg260w since week one at 30 cm distance? Or treat them the same as photos?

    Treat them the same as photos mate. Maximum lighting for autos is about the length of time the lights are on, not the power or the height of your light.

    I tend to have my 250w QB's about 45cm away at seedling stage but I dim the board down to 90w for the first 2 weeks.

    Then I let the plant grow and try and keep them around that distance throughout the grow, dialling the power up from when stretch starts or when pre flowers show.

    By week 4/5 of flower the boards are running at the max.

    Only difference for autos compared to photos is, you generally need to start dialling up the power quicker than photos just because they grow quicker.

    Hope this helps mate.
