This helped my in-door plants survive 2026 heat wave!!!!
Been using this for 2 months now, and it has made all the difference with my in-door hydroponic garden during this hot summer heat wave. I was able to keep my thermostat between 78-80, and I used this with each feeding which protected the roots and aided the plant health during this hot spell. Without this, I would have been forced to lower my thermostat back down to 68, like last year, but I avoided that this year because of this Hydroguard. I'm growing all green vegetables, and generally when the in-door temps go much past 70, the plants bolt and wither:, but not this time around!

A must for using tap water with enriched soils - if you love your plants, do the right thing.
Takes the nasty out of tap water. Doesn't mess with pH and plays well with enzymes and nutrients. I have used it for five years, indoors and outdoors, seedlings through harvest, in soil and medium, dwc hydro and waterfall hydro. Since I started using Hydroguard, I have never lost a single plant to root rot. Even in large reservoir circulating hydro setups, a quart goes a long way. Suggested dosage is 2mL to a gallon, so I can run a 27-gallon recirculator for about a year at gal/wk between resets. Just put it on your list if you're an indoor grower, you need it.

It works for me.
I've used hydroguard for several years in a small hydroponic grow using 5 gal. black buckets. When I get root rot, I lift the root ball our of the bucket and strip off all of the rotted roots by hand and put back in the bucket with new water and hydroguard. I put the water level up to the bottom of the net pot. I have had great luck with the roots coming back nice and white and great production. I also pour some of the water from the top to coat any roots in the net pot. Just my experience.

Seems helpful
So it is hard to rate this product. I'm not sure what effect it should have. BUT this is what I have observed. I moved from a bunch of Aerogarden and Salad Box grows to one large integrated system where the water flows from plant to plant. We had a fire, lost the mud room in the rebuild due to budget. I decided one large system would be far more attractive in the public area of the house. After a while, things seemed to stop growing. In addition, I've had more trouble with aphids than ever before. I did research. My reading indicated that it is harder to balance the needs of a variety of plants rather than similar plants in small containers. They recommended a water additive such as this. The claim is that it makes nutrients more available to plants. One week after beginning to use with each watering the plants, especially greens, are growing nicely once again. Literally in two days most of the greens doubled in size. The tomatoes seem to be ripening more quickly. I see no difference in the aphids problem (it is summer and near the main door). Nor any difference in the herbs. I hope this information is helpful to others.

Must-have for my semi-hydro setup
I use Hydroguard with my semi-hydro plants and it’s made a noticeable difference. My roots look a lot healthier and I’ve had fewer issues with rot. It’s not a miracle potion, but it definitely helps keep everything stable.

Saved my dying plants from advanced stage root rot
I had a couple plants that unfortunately were overwatered by my SO and developed root rot, by the time I found out it was already in the advanced stages, 70% of the root system was brown and mushy. I searched desperately all over the internet for a solution, most sites said to toss the plants because there wasn’t a cure and I found a couple that suggested using diluted hydrogen peroxide which at first looked promising but it didn’t seem to fix the problem completely (I had put all my dying plants in water so I could see the roots). I stumbled on this product after doing a search for root rot treatments (I scrolled quite a few pages before finding it ) and bought this product. Read the directions and added 1-2 drops of this to the water my plants were in and waited. About a week later all my plants were starting to grow new healthy roots and the dying ones were starting to look better too, even the sad three inch stick that used to be a Chinese evergreen but had been whittled down to nothing as I tried to save it, it only had one dying root but slowly I’ve noticed another new one starting to emerge, it’s a miracle and it’s all due to this product!

Goodbye pythium !
Very effective to control system . You will not have issues with pythium with a low dose of this . It is expensive but a litre treat a huge quantity of water and it works out far cheaper in long term than competitors. Very concentrated, arrived fast and discreet. Great seller
