How long do hydro nutrients last?

[wheatgrass]

Another question everybody. How long are General Hydroponics nutes good for after opening. It is a lot less per cycle if purchased by the gallon. Thanks.

I have heard a couple to five years if well stored in the dark and cool places

by the way... i had to post my answer twice because you asked the same question in two different posts. Its more simple for all to post a question in only one place here, my opinion of course. Thx

I was a sucker when I first shopped for growing equipment. Bought a gallon of each GH Flora Trio (guy must have thought I had a big hydroponic grow happening) didn't know where else to go to get it so...........wife almost killed me cuz I bought the pH testing pen as well $300 for everything. Hadn't purchased the tent yet - thought I could grow in a shed - but found out it had poor ventilation.

That was purchased 4 years ago and still using it - what I have left should last me for this and my next autogrow this year. Although - growing only autoflowers the past two years I have a lot more Floragro than anything else.
