    Correct. 2 x citizens, 1212s. 3500K Current 700mA Volt 33.9 power 23 watts
    Hlg 60h c700 v range is 50v - 100v.
    2 x 33.9 v = 67.8v. Which fits into the min max range of that driver for a total of 56 watts.
    If that helps.....

    Hello
    I do use LED lights for my full grow (from start to finish) what I would like to know is how far you have your lights from your plants. I am using 3 x 1500 watt LEDS and I can only get 15 oz per grow. I have always done 6 plants. I also lst and scrog as well. The reason I ask is because I have set my lights at 18 inches above my plants when in flower. So I was wondering if I would be better off going to 24 inches.
    Many thanks
    Yours Cindy

    I don't think you will get an answer from that guy, he hasn't logged on since 2010.
    But if your not seeing light burn or bleaching on your plants then stay as you are, unless your not getting even light spread and then raising them will help with that. :bigjoint:

    What sort of space are you pulling 15oz from?

    To double your yeild you need to double those lights.
    But why not upgrade to something better to fill your tent with light?
    Hlg QB's are really good, as are cobs.
    You don't have to rush and buy all at once, some people can' afford to

    This is good in a 2x2 or they have a 20% off 1st Feb I think on a hlg550 - 4 x qb, covers a 4x4 real nice..

    Which other light are you getting, the same as you already have?
    Yes , keep them about 2 ft away at start n let them grow into light.
    My first leds were burples like yours but there are far better lights now that are white and they give you a lot more bang for your bucks.
    Maybe save an Ounce of your grow to sell to reinvest that coin on a phased upgrade to cobs/QB'S bit by bit..... you'll not regret it :bigjoint:

    Depends what they cost and how hard you plan on running the 1212s, to cover what space ect.
    You would have to run the 1212s pretty hard to get the 300w out of 4 of them and doing so would lose a lot of efficiency making the tunnel lamp more efficient.

    So what space are you wanting to light up and what is your budget?
    How much are the tunnel lamps?

    Have a look at the ledgardener link a post above. Look at his 3x3 strip set up. You should be able to shave off a few dollars cutting out fancy hangers and heat sinks, I think you can just use aluminium angle for heat sink with strips. @Randomblame will be able to say for sure. That's if your interested in really lighting that space up and getting good efficiency to boot.
    Going down the 4x 1212 route wouldn't be a great option other than just saving cash.

    Nothing wrong with Citi1212's but 220w is on the low side for a squaremeter. But because automatics can handle up to 18-20h of lightning, the DLI should be good enough to get full developed plants. But with regular seeds 220w is really on the low side and you'll get no more than ~250-300g of popcorn bud. I would at least add another two COB's before you try to grow regular plants.

    You Will Do Just Fine With Citi's In Your Setup. If You Look At My Citi 1812 80 Vs 90 Cri Grow I Use 250 Watts For A 2.5x3 Area And My Buds Are Rock Solid :weed:
