    I just got some iron chelate from GLA. How should I go about make a stock solution and how much should I dose and frequency? My currently dosing EI plus CSM+B.

    Thanks,
    Jeremy

    GLA doesn't tell percentage of the iron. So, it can't be calculated.

    If it's pure dtpa-iron then it should be about 12.5% iron.

    This is what GLA states about their iron. "The nice thing about our Iron Chelate is the DTPA factor combined with EDTA iron in CSM+B. What you have there is basically PMDD of TMG, expect really nice results from our Iron :)"

    Do I really need to make a solution or would it be possible to just dry dose it?

    Thanks,
    Jeremy

    I'd just mix with the CMS+B at 1/4 to 1/3 by weight, then dose that as you did prior.

    Yes, that is much easier. I sometimes make things harder than really need to be. Now, I just need to get a good scale. :)

    A good scale won't hurt. ;) If you think about it in this case a good scale is just anoter complication. :eek:

    Adding a quarter to a third more isn't exactly an exact measurement. :p

    Here is to life; uncomplicated! :cool:

    Yes, certainly +1 for making it easier, I think you should be able to eyeball the 1/4 to 1/3 by weight pretty well.

    A scale can be had for 20-30$ tops on line for 2 decimal places, or 10milligrams, a few more $ for decent 0.001 gram scale, maybe 80-120$ range?

    Not a bad thing to have if you want to be more precise, but it will not help you really become a better horticulturist.
