Should Nutrients be Stored in the Dark?

Or can I just keep them out in the open?

Actually that's the kind of attention to detail that helps a lot.

I wouldn't worry about indoor light.

Sun-light - definitely ages plastic and some nutrients.


Temperature do - living organisms like Bokashi probably need lower temps.

i think they are fine.

If they are opaque bottles, I wouldn't care either way. But, I would check the temps. If they are opaque black bottles under a 1000HPS, I bet the temps would get pretty hot in there. Microbes might die, and reactions that require heat as a catalyst might start to happen that you don't want, or enzyme products could denature.

I figure that if I'm paying $XX (a lot) for brand-name nutes, I should treat them well, keep em around 72-75 degrees, out of the light, caps on tigtly, humidity is reasonable etc. It also help to isolate things. If you're all of the sudden having a problem, you can safely say that it's not the nutes and look elsewhere.

I should have mentioned that I store the nutes in glass transparent bottles.

So, I can just keep them in the same room as the lights as long as it doesn't get too hot?

I would shade them and use opaque. Light is not going to make them better.....

They will certainly degrade under light/heat. They will also start to grow things (algae and others). I would store 'em somewhere else AND use opaque containers. I wouldn't pre-mix more than a month's worth at a time.

Most fertilizers will give a temp range for storage on the bottle. Almost all say store out of light, not just sunlight. Especially if in glass.

I spend quality money on quality nutrients, so they are in the dark, and climate controlled at 70f.
