    Hey guys i was reading somehwere that it isnt a good idea to spray your plants
    with water while the lights are on becouse it may burn it is this true?

    ive bin spraying my plants just as the lights go off at night
    but is it ok to spray them while the lights are on?

    I have burned some plants by spraying with lights on. The water droplets act as a magnifying glass and burns the leaves. I would not recommend it.

    I do like you stated right before lights off. Be careful not to spray the bulb I did once on accident it it popped went off and that was that for the bulb.

    Nope not safe under hid lighting , the water drops act as magnifying glasses and burn your leafs. It's okay if using CFLS though . You read right .

    If you use some sort of spreader/sticker or wetting agent it shouldn't be too much of a problem. These help break up the surface tension of the water thereby preventing droplets from forming. Also, good air circulation will help since the water will dry quicker. I occasionally spray with lights on and don't have any problems. Of course, I move the plants that are directly under the HID to the perimeter. Just be careful and you should be fine. You don't want large droplets sitting on your leaves for too long.;-) Happy growing!:leaf:

    IMO, the best time to spray is a couple of hours before lights come on.
    1st. turn all fans off
    2nd spray plants
    3rd turn fans back on
    my biggest worry is introducing mold into the room. wet plants and long periods of darnkness concerns me.
