Description

Hydroguard is back with a new, clean look and a more powerful, concentrated formula. Hydroguard's reformulation makes it even more effective than before. Its unique formula, available exclusively from Botanicare, contains an isolated form of Bacillus bacteria known as Bacillus amyloliquefaciens. This scientifically isolated bacterium was selected for its superior ability to amplify root mass and vigor, especially in hydroponic gardening, when compared with the more common and well known Bacillus subtilis species. These highly specialized rhizobacteria assist in the breakdown of organic materials, and may increase nutrient availability.

Don't need much.. I've been adding 1-2TSP per 5gallon during DWC res changes with great results. Doesn't change your PPM or PH. Keeps roots healthy. Update : This stuff really works. Look how white and healthy these DWC roots are.. Hydroguard has the following scientific aspects and proven uses: Scientific Backing: Hydroguard contains beneficial bacteria, notably Bacillus amyloliquefaciens. Scientific studies have shown that Bacillus strains have positive effects on root health and protection against harmful pathogens in hydroponic and DWC systems. Root Health Benefits: The active ingredients in Hydroguard promote root system vigor and resilience by colonizing the root zone with beneficial microorganisms. These microbes help prevent the growth of harmful pathogens like Pythium, Fusarium, and other root rot issues. Proven Efficacy: Research studies and hydroponic community feedback have highlighted Hydroguard's effectiveness in maintaining a healthy root environment, reducing the risk of root diseases, and enhancing nutrient uptake. Preventive Action: Hydroguard's use as a preventive measure has been noted in hydroponic systems, offering a layer of defense against potential root problems, ensuring plants have a strong foundation for robust growth. ... show more

    • Must-have for my semi-hydro setup
Size: 1 Gal Pattern Name: Inoculant
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.

    • Best thing for plants
Size: 1 Quart Pattern Name: Inoculant
Amazing product: makes hydroponics much easier. All you need to do is not nutrient burn your plants after adding this stuff. Keep in a cool dry place and will last for years. Also works as a hot composting innoculant with OUTSTANDING results. Literally overnight started cooking the bad guys out of a rotting layer that an arborist had sandwiched between the wood chips they dropped off. ... show more

    • Seems helpful
Size: 1 Quart Pattern Name: Inoculant
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. ... show more

    • A must for using tap water with enriched soils - if you love your plants, do the right thing.
Size: 1 Quart Pattern Name: Inoculant
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. ... show more
