    Is there any reason I cant pre mix(dry no water) my KNO3, KH2PO4 and MgSO4 or am I going to cause a huge explosion that will kill my house?

    Cheers

    The problem with doing that is if you then decide that you're not dosing enough NO3 for example you can't isolate it and selectively add more of it, you'd have to add more of everything (i.e. in the mixed power) just to get more NO3.

    Yes, good point, so there is no health and safety reason not to mix then? I have my mix pretty much the way I want/need it and would like to make some ready (in bags) for when I'm busy or not around 8)

    I wouldn't think I would be a problem, but I'm no chemist! :lol:

    The only reason I can think is that you won't know how much of each is in each teaspoon of ferts as the ratio's will be totally different each time.

    I mixed mine in these containers, which gave me a 3 week supply of Micros and Macros ;)

    The containers where purchased at Muji stores, 4 sets to give me 3 weeks worth. Used them for a couple of years and now just using the DIY mix with an auto doser.

    Hope that helps ;)

    Perfect Paulo, just what I wanted, just wanted to make sure it was ok to do :D

    Garuf, I'm only wanting to mix(with the right ratio's) and store like this, then make a normal mix up as I normally would(in water), so there would be no uncertainty of the levels dosed.

    KNO3 = Potassium Nitrate

    KH2PO4 = Mono Potassium Phosphate

    MgSO4 = Magnesium Sulphate

    Take a look at the turorials section: EI dosing using dry salts: this is the link http://www.ukaps.org/forum/viewtopic.php?f=34&t=1211

    An extract from that:

    Nitrate (NO3) 20ppm per week.
    Potassium (K) 30ppm per week.
    Phosphate (PO4) 3ppm per week
    Magnesium (Mg) 10ppm per week
    Iron (Fe) 0.5ppm per week

    Hi,

    Right I downloaded the dosing chart program thing that is posted somewhere on here and I know what to mix up now so thanks for this...

    One more question....

    i would like to make up a liquid batch....would I be able to make up several weeks worth in one go and just measure the right ammount of liquid each time (subject to shaking the bottle) or would this not work?
