I started collecting ferts for EI and came up short on KNO3. It is being banned here because of its potential for being used as an improvised explosive.
Calcium nitrate will be my next best bet but our local water is already quite hard.
I didnt measure gH but the kH is around 13-16 and pH is around 7.5. I think the entire island im standing on is an enormous limestone.
Im currently reading up on urea as an alternative nitrogen source and thought i'd ask you guys what you think.
So far, ive come across a lot of mixed opinions on the matter of using urea.
Thanks!
