    Outside you can sometimes get away with with using no fertz. If the quality of the soil is good enough, there will be enough food already in the soil. I have found that the most fertile soil outdoors is in abandoned overgrown farmers fields. Grow great plants there without a drop of food. But other types of soil will require feeding to get better results. The plant will tell you when it's hungry. When it starts to yellow from the bottom up, it's time for dinner

    ;)

    What is the NPK ratio of the tomato fertz you have??

    Well you could grow in a good soil and add no ferts and get a yield, maybe a reasonable yield.

    But most of us pay good money to buy ferts, or like me go to a lot of effort to make our own organic ferts, because it is cost effective. You will get a much better yield from a fertilised plant than from one simply left to its own devices.

    heres the tomatoe food ingrediants i have ( Miracle grow brand )
    total N= 1.4%ammoniacal nitrogen
    2.6% Nitrate nitrogen
    14% Urea Nitrogen
    Availabe Phosphate ( p2Os ) ........18%
    Soluble Potash ( K2oO)..........21%
    Magnesium........... .50%
    .50% water soluble magnesium
    copper .50%
    water soluble copper .05%
    iron .10%
    maganese .05%
    .05 chelated maganese
    Zinc .05%
    .05 water zinc





    also says its derived from ammonium sulfate, pottasium nitrate, urea ,pottasium phosphate, magnesium phosphate, copper sulphate, iron EDTA, maganese EDTA, and zinz sulphate


    so is this stuff all good for my plant? says to mix 1 TBSP into 1 gallon of water

    Ok so the NPK ratio is 18-18-20, that's an ok all around general purpose food good for the vegetative cycle. Come flowering though you'll need to get a flowering fert though. With flowering fertz you want those last 2 numbers higher than the first one

    o yea and how often will i need to water with the ferts?
     
  12. #12 spliffmeister!, Jul 19, 2006
    Every two weeks ia about right

    Depends TOTALLY on your climate. If I do not water every 24, my plants are tinder dry and wilting by 36.

    But I know guys in the UK who only ever water every 2 weeks.

    HE said water with fertz, not just plain water. If you water with fertz every 24hrs you ain't gonna have them plants for much longer!
     
  15. #15 Spanishfly, Jul 23, 2006


    I water with organic ferts every 48.
