Mixing larger quantities of nutes

[smoorman]

I know that generally speaking nute solution shouldn't be kept around too long, but what if a person were to mix up a week or 2s worth and have a circulation pump in it 24/7? Keep it in a black tote no sunlight Etc?
Any experience or thoughts?

maybe a week no more

Assuming you mean crystals. A couple weeks isn't going to hurt it & no need to circulate it ether. However why? It takes up less room to mix it as you use it. Now if you mean organic stuff then use it by the third day.

GH Flora Bloom. I'm going to be gone for a couple of weeks and trying plan ahead for house sitter.

I haven't used that exact one but I had some left over seedlings starter that is mixed up Feb 9th. It looked fine to days ago but when I went to use it today it was full of mold.

I've never used organic nutes for it, but i regularly make up a couple of 60L totes that last me a week or two without issues in DWC. Organic nutes may be different though.

Which nutes are you using?

Remo Nutrients, full line plus silica (ArmorSi), plus an aerated worm casting tea every two weeks. I just give it a good stir before top ups or rez changes.
