Help please...Flourish Question

  1. tommy jr. Member Member

    It says on the Flourish Complete that it is best to refrigerate after opening but not required
    HOWEVER the Flourish Excel does not?!?!?

    Why does one say to and the other not?
    Also what is the shelf life between refrigerated and non?

    Flourish Comprehensive and Flourish Excel are completely different products and will have very different storage requirements.

    Comprehensive is the complete plant food. It is primarily comprised of micro nutrients and have very little macros. There are additional products that can be added to truly have a complete fertilization plan. This product suggests cold storage as it is possible it could begin to ferment and grow mold. If you are very careful with your measurements and don't rinse out the cap, then the product remains fairly stable. I have never refrigerated my bottle and it is still good after a couple of years.

    Excel is a carbon supplement. It is used to replace CO2. This product is very stable by comparison and can last many years at room temperature.

    She's got it right on the head again!

    I would also add that I do not refrigerate my flourish comprehensive either.
