    Are there any charts for recommended light distances from plants for different stages for LED lights?

    I might finish my current grow with the LED panels as they should arrive this week if I can work out the correct height so I don't screw the plants up lol.

    Depends on manufacturer as it probably varies, but my IS is something like 30 inch for seedlings. 24 for veg and 18 inch for flower

    What happens if you treat seedlings like flowering plants with led? I do that with hps/cmh and no problems.

    Anyone got pics of seedlings or young plants that were given too much light?

    So these were shipped from China on Friday and arrived today,I removed the HPS and swapped the 6" fan down to a 4" fan for extraction.
    These came with dimmers attached which is a bonus,took me 1 1/2 hours to swap everything including the ducting and fans over but its done now

    Just saw this. I'm fine blasting seedlings on full power on IS ish150 LED. As long as I stay at the right height, full powers fine. Can't say it'd be the same with all led's

    Thats very true, height has exactly same effect as dimming. Double the height, quarter the ppfd for example

    If you need the energy in the room for warmth then its a great idea.
