How long can I keep Hydroguard after it’s been open?

[TheGreek_978]

Hey guys,

I grew last year for my first time and got 3 1/2 ounces on my first grow not too bad I think. My grow ended in October of last year and I still have plenty of hydroguard left but on the bottle it says don’t use after 6 months.

Would I still be able to use it now and into my next grow that I’m starting in April again or would I need to buy more hydro?

Thank you

Here's a thread that explains the Hydroguard date code, and puts the expiry of an opened bottle at 6 months.

Reading lot number on Botanicare Hydroguard

Just received this from Botanicare. This is how you read the lot number on Hydroguard to tell if it is still viable. Hope this helps.
