    You use 25 pounds of a 15-11-29 fertilizer mix in a 30 gallon concentrate tank, and then use a 1:100 dilution in your injector. How much nitrogen are your plants getting (in ppm)?

    Use the following formula:

    ppm = (% fertilizer) x (lb added to tank) x (16 oz per lb) x (.75) x (100/gal of concentrate) x (1/ratio of injector)


    number 19

    Title changed so it dosent fall under rep abuse. - KSR
  2. You're forgetting to divide by the square root of banana

    Heres a chart detailing it .


    No but seriously, I have no idea what any of that crap means.
  3. 150ppm nitrogen

    ppm = (% fertilizer) x (lb added to tank) x (16 oz per lb) x (.75) x (100/gal of concentrate) x (1/ratio of injector)

    PPM = (15) X (25) X (16) X (0.75) X (100/30) X (1/100)
