Shelf life of nutrients?

Is there one? I use advanced nutrients and I checked there website but didn't see anything.

If its not listed I would imagine its indefenant but exposure to light is not good for them and once its mixed it shouldnt be stored to long.

i think it's like something you might hvae on a store shelf - the second you break the seal, it starts going bad

things that are organic will go bad faster since they don't have preservatives in them

so long as you don't open up a bottle, you can use it forever

i mean, if you're paranoid, talk to the guys at Advanced Nutrients...their customer service department is really good at answering questions...might want to call em up if you're worried

don't want to be giving the babies something nasty...
