Is it ok to switch lights 3 weeks into flower?

Discussion in 'Growing Marijuana Indoors' started by pfd161, Jul 23, 2018.

  1. I've got some nice LED strip lights 300w x 2 being delivered Wednesday. The girls have been under a 600 watt HPS and are doing well. I'm struggling with heat a bit and power consumption wonder if it's ok to switch?

    I'm hoping the LED's will give me a bit better coverage in my 4x4 tent

    Thanks for any info.

  2. Long as you keep it on the same cycle you should be fine. It took my plants a week or so to get accustomed to MY HPS going from CFL's. I don't think you should have any real issues.
     
  3. We don't know until we know exactly what LED lights you are using .
    Most LED lights do not use the advertised wattage .
    Most do good to use 40% energy that the led light company advertises .
    If you paid less then a hundred bucks per ;light then your answer is no.
    Top line 300 W LED light will run you some where close to 500.00 or more .
    Two of the cheap 300 watt LED lights will not hold a candle to the light a 600 W HPS .


    My 300 watt led mars lights actually are 111 W.
    You cannot rate a led Lights performance just by wattage , Watts is power consumption only and has nothing to do with color spectrum or coverage .

    No one buys that light or Light kit and doesn't know if the light will Compare to HPS lighting.
    Right now Samsung light engines is the newest technology .

    Glade you got some decent lighting ..

  9. The lights you mentioned I haven't researched .
    Me I am just learning , been making LED light kits but using slightly old technology ( Cree/COB Light engines technology ) using colored Cree bulbs .
    I use a makers controller which I do think is up to new technology standards .
    Samsung is the latest and greatest LED bulbs and light engines on the market ,

    Cheers
