    Default Nutrient question for dwc

    Hi all hope your all good and willing to offer me some advice
    I’ve grown before many years ago but in soil
    This time I’ve set up a 4x4 foot tent and 4 bucket dwc
    Now here’s my question please go easy
    My plants are two weeks old from seeds and have been transferred in to
    Their net pots and are doing well , I’m using canna start and rhizto ,
    On the back of these nutrients for example is says on the canna to mix 20-30ml
    To 10l of water which is fine.
    But do I mix 3ml to 1L of water and add that to the nutrient tank ???
    Or work out the total volume of my four bucket dwc and then add required amount
    I have bluelab truncheon coming Monday which will help.
    Many thanks guys and gals

    Sounds like you're running a recirculating deepwater culture system, which I have never done. But a logical approach would be to set everything up with just clear water no plants run the system a bit and see if you're happy with water levels and go from there. In other words measure all the water you put into your system before you run it and use that to make your adjustments.

    Once you get going you're going to want to make your nutrient adjustments based upon a combination of your water levels your EC and your pH..

    This chart can come in handy

    my advice is to use half the recommended dose, in rdwc.
    But you will be better off with a ec meter, and you will need a ph meter too.

    set the ec to 0.6 and the ph to 5.8,

    and let it run up to 6.4, then re-set it back down to 5.6/5.7, and let it rise again.
    before you know it you will be growing things like thisClick image for larger version.
