I'm working on a spread sheet for making DIY hydroponics ferts for emersed people.

Can someone (Edward ..hint hint) check these numbers

Suppose I add 100grams (just a number for the sake of calculations) of the following and add enough water to make 1000mL solution (assuming 1g/cc mixed):
KNO3
NH4NO3
KH2PO4
MgSO4
K2SO4
Calcium Carbonate
Plantex CSM+B


This will result in the following concentrations:
N 4.30%
K 11.60%
K (K2O) 10.89%
P 2.28%
P (P2O5) 5.23%
Fe 0.65%
S 5.33%
Ca 4.01%
Mg 2.16%
B 0.118%
Mn 0.187%
Mo 0.005%
Zn 0.037%
Cu 0.009%


Is my math correct here?

Thanks!

Hey Rolo, actually (so far), we are both right. You probably missed that N comes from KNO3 and NH4NO3 in my example..two sources. When I used the spread sheet and made NH4NO3=0.0g, I got the result you did.

Thanks for checking thus far.

Ah, that's right

he better bring us back some goodies

Hey Edward!

Hope vacation treated you well


I thought all those chemicals were pretty easy to come by. Everything exce[t ammonia nitrate is from GregWatson. AmmoniaNitrate is an uber common lawn fertalizer.
