well,thats good to hear.I have grow big &tiger bloom you think ill be ok with those,thanksOrganics usually 1-2 years. All depends really. I have heard seaweed/kelp extracts last a long time.
Chemical ferts do not expire unless contaminated somehow. (from usage, etc)
For instance I would not use Pure Blend Pro if it was older than about a year and had been opened already. But I would use GH Flora nutes 10 years later as long as they were not discolored or cloudy.

whats that do?Store your nute bottles upside down and they will last.
