do nutes have a shelf life..............

[stoner]

either opened or unopened?

 

are they still ok to be used after a few month or a year even if they have been opened?

I've used stuff thats donkeys years old to no ill effect.
Nutes are nutes and i cant see how it can go off.

Even organic stuff, usually made through some sort of fermentation of sorts i cant see going off, only better.

Recently i used some Fish emulsion that was growing a layer of fuzzy stuff on top.
Shook the fucker up, mixed it up and fed my Kratom plants.
They loved it.

If in doubt, chuck it out.....in the garden not the toilet

 

Peace

I’m using a 6 year old bottle of bio grow I found having a clear out and so far after 6 weeks of flowering I’ve seen no ill effect, there you go...

Using GHE Trio here and the only issue I have found with the Flora Grow, green one, is that the solids part company with the liquid leaving a salt like crystal structure in the bottom of the can.

Get round it by getting the whole thing to room temp and agitating vigorously, sometimes for quite a while, until all the solids are dissolved again.... 

Other than that no issues with Nutes from GHE over 2 years old so far

Depends on how they've been stored, if outside in a shed or similar that gets low night time temps bottled nutes will denature over time , if stored above say 8°c they should be fine for absolutely ages , I'm currently using up an ancient 20L drum of maxicrop and it's still spot on.
