CAL-MAG---> how long....

[the gnome]

I fill up 32 gallon plastic trash cans swith RO water for the garden.
how long will calmag last once its mixed with water?
I would be nice to spike water in the trash can w/camag
and have on tap when I use it.

Ive left liquidkarma in a bucket and after a few days mold starts growing

I think it all depends on which calmg is used. I am currently using Technaflora's MagiCal and I have left it in an open bucket for 7+ days and it looked and smelled fine. I also have General Organics CaMg+ and it starts to turn funky in 2 days.

As long as you have no organics in it it should be fine.

If it is chem only.

i'm using botanicare calmag, anyine use this long term in their water?
If your using RO water do you need to use it every watering?

a week tops, i found that by mixing nutes as needed uses less . so if your feeding 1000 ppm when you feed but ur res has nutes for a week then if you mix as need every watering you only need to feed at 800 ppm as the nutes seem to be taken up freshly a bit better then when they c temp fluctuations.
