Do Nutrients expire?

I have some advanced nutrients from 2009- just wondering if they would still be good?

Yes they do. Most 12 months is max. 2009 is way over so trash it.

thanks much

If they're salt nutes, they last near forever. Organic components will spoil with time. cn

i don't think they are organic- advanced nutrients sensi grow and bloom?

They mention a "proteinate" as a chelating agent. It's the only component that could spoil, and if it does, I can't imagine bad consequences. Basically ... if it doesn't smell like an Albanian brothel on coupon night, you should be fine! cn

It's remarkable what one can do on one breath, back in the days of being young and fit. cn
