Hydroguard

yea, this stuff is good

Excellent easy to dose, probably saved my plant a time or 2 and didn't even know it, I used as a precaution

stopped my root problems, however doesn't magically undo damage. use preventatively

Never fails great product.

Definitely helps in Hydro applications like my DWC buckets to keep algae down but with RO water, a simple 10-15 drops of Phosphoric acid keeps growth to a minimum. I don't know if it helps in my soil applications.

At first sign of root issues, I got a bottle of this stuff and it kept my roots healthy for the rest of my grow

Without it I would expect major root rot.

Roots weren't that bad considering the high res temps.

This helps so much. Res changed every 7 to 10 days and with the heat wave the res was hitting high temps and the plants roots looked good.

didn't save the bud rot this time
