I wouldnt do it just Bc. its easy to mix .. unless you know you will use it with in a day or two ..
I just cut my dosages in to ½ or 1/4 or 1/10 witch one is most easy .. and if any water/nuts left in the can when Im done .. I give it to my house plants .. they love it ..
Im not so concernd about the nuts .. more the water .. I would like to provide my girls with fresh water ..not weeks old water from a plastic can etc.
might just be me .. dunno .. but if you are going to do it ..make sure to check PH before you use it and maybe try to get some air/bubels in ther ..
