how do i store un-used nutrient solution

well im planning on feeding my plant in the next day or 2 once the soil dries out, so on the back of the package for my nutes it says outdoor plants mix a packet with 4L water and indoor mix a packet with 8L of water, so since im indoor il have about 7L extra nutrient solution (give or take), and i was wondering how i would store this, or if i should just dump the extra solution

dump it unless your gonna use it within a couple days. but if you do keep it make sure to store it somewhere cool.

ok thanks! il just dump it then, wasnt sure thanks for clearing that up!

agree, or do as I, use it on your normal house plant`s if you got any ? mine just love it, soon Im out of room actually kind a exploded after I begun to grow MJ

If you're gonna save it you need to get a small air pump and airstone to keep it for more then a few hours. If its not aerated all the beneficial organisms in it will die.
