    Hi, first of all I would like to say hi to everyone as a new forum member, great forum I've followed for a while but only just become a member so hey all.

    Secondly to to question in hand, here goes I have 24 plants with poor root growth to previous ones.

    24 plants half way through week 4 12/12
    iws flood & drain 5 floods 40 mins each flood

    5x 600w hps
    sms fan controller @ 23
    8" out 6"
    ec 1.8 full strength as feed chart says from local grow shop
    ph 6.0
    aqua pots
    4" rockwool
    canna aqua a-b flores
    canadian express wilt gaurd
    canadian express regan a root
    rizatonic
    hygrozyme
    canna boost accelarater
    budda's tree pk9/18

    everything looks fine to be honest, but the root growth isn't the same as previous times, there's healthy white roots, quite a lot dangling but there not matted to the shape of the outer pot like previous times, so could any thing be better maybe??
    I was thinking maybe the medium is staying a little to wet? And should I reduce the flood time or take a feed off maybe??
    Any help greatly appreciated.

    I'm in hydroton and do 4 floods for 5 mins. Also, at your stage I would be running ec 1.4-1.6 and pH 5.8, but thats just me.

    Depends on your pump and system.

    sounds like a flooding problem, 40 minutes seems a bit long. are you using an aerator in the reservoir?

    No, I used these systems in the past and always floods for a long time to reach all the pots, when set up I timed how long it takes on a flood to reach the desired level in all the pots.

    I'll try again with this guy

    what is the temperature/

    its one of the most important things and you dont know it

    that is lazy

    is it cold where you live

    you posted about slow root growth. what system do you have a flood table or pot sites
    I only flood for 45 minutes out of a day you posted that your flooding for 3 and a half hours a day.

    And 5 floods only with lights on at equally spaced intervals throughout the light period, each flood taking 40 mins because that's what it takes to fill every pot(24) to the desired level, any less of a flood time would result in some pots not having as much water as others
