Hydroguard 1 qt

This is a must have when you're growing tomatoes 🍅 in a bucket system. I wouldn't go without it. Yes you can buy other products that are less expensive and you use much less of but for me I like hydroguard. Makes me feel better knowing my water will be ok.

Great product. A must have for hydroponics

I love this stuff and the price is great on Amazon. Hydroguard is a life saver for propagating/growing plants in water. My success rate has increased 95% since I've started using it. Shipping was good - no leaks or problems.

I grow using an RDWC system and recently switched from running sterile to using beneficials, and this product works great for that. The first time I used it was a couple of years ago when a friend suggested it to help prevent issues with slightly high water temperatures. At the time, I was running a sterile system and didn’t realize that it was counterproductive. The sterilizing agents in my system were actually killing the beneficial bacteria in Hydroguard.For anyone who started off like me and didn’t know this, now you do. This product is ineffective if you’re using any sterilizing agents such as hydrogen peroxide (H₂O₂), hypochlorous acid (HOCl), or bleach. It should only be used in a living system.

I use this in my DWC buckets, keeps roots bright white, also eliminated any filming inside the buckets. I don’t grow hydro without.

This is so easy to use and has clear directions for measuring and so far it does what it says it will do. My algee seems to have stopped at least for now. Will get more soon.

Got a bounce back with new roots, H2O2 not the same. We'll see.

No root rot in mid summers heat!!
