DrJynx86answered grow question 4 years ago As long as you keep them away from heat and light sources that's ok.
As a rule, I always smell all the liquids I store in the grow room, be it leftover nutrients or maybe any kind of spray for bugs. As long as it doesn't smell bad (strong, rootten) and just smells like water, it's ok to use.
Keep on the great care!
Happy smokes!
