Expired Nutrients

Hey everyone,

I have some Canna brand nutrients from a year ago and Im wondering if it is still safe to use them.

The nutrients I have are Terra Vega, Terra Flores, Canazyme, Rhizotonic, PK13/14, and Canna Boost.

Most of the bottles have a date on them from mid 2008 which I am assuming is the shelf life, but it doesnt state that on the bottle.

They have been in a cool dark place (black trunk in a closet) if that makes any difference.

Thanks. :jointsmile:

cool and dark is the key ... chances are, the nutes are still good ... at worst, they may be weaker from age ... or stronger, if any evaporated ... no biggie either way, everybody tends to over-fertilize, anyway :D

Thanks. Im gonna just buy new Coco and A&B, but ill give the older cannazyme, rhizo, & boost a try (mainly because they are the most expensive)= :D
