I have veg and bloom nutes I have had for about a year,and bag of fox farms.Had to take a break for a while,they have been kept in a cool,dark spot.Hope I do not have to buy more still 3/4 full,thanks
If theyre organic, they probably will go bad, but a year, I'd look at them in a glass, make sure theres nothing growing in there, make sure the smell doesnt knock you out, and go with it. Same with the soil. Chemical stuff is probably good forever..
