Shelf Life of Flourish Liquid Ferts
I was just having a conversation on another forum about how my plants (5 sword plants) aren't looking to good.
Maybe its the lack of sufficient CO2, or the degrading of the light bulbs. I mentioned that I have large jugs of your ferts and dose according to your suggested schedule, and also use root tabs.
It was suggested that perhaps the ferts have lost their potency, due to age or temperature fluctuation (they are kept in my living room in a cabinet below my QT Tank. It does get seasonally warm occasionally but never extreme.)
I pulled out the receipts and found the dates purchased: 8/1/2008 for most of them. For the iron & trace it was re upped 2/10/10.
As I explained to the veterans on the forum, I shake and fill your 250 ml bottles from the jugs, for ease of dispersing, and use a syringe.
What is the shelf life of your ferts?
