So i have an abundance of nutes laying around guano ewc and snow storm ultra also kelp meal and im getting a bunch of free samples in the mail from various companies so im wondering how long on average do nutes stay good for obviously i wont be able to use all of them this season but i'm wondering how long they'll stay good for? anyone have any guestimates it would be greatly appreciated. Thanks, William H Bonney
Liquid nutes that are organic based i wouldnt keep longer then a year but if refrigerated can last a bit longer. Dry ammendments will last for years if sealed up proper to avoid any moisture.
