    I am addressing root problems in my first ever hydro grow and seek counsel from those more experienced please.
    These two products are similarly priced, have the identical active ingredient, but at very different strengths according to their labels. So different that I question if one of them has their numbers mixed up.

    Hydroguard: bacillus amylolquefaciens 0.038%
    inert ingredients 99.962%
    Recommended usage: 2ml/gal

    Southern Ag: bacillus amylolquefaciens 98.85%
    inert ingredients 1.15%
    Recommended usage: 5ml/gal

    If Southern Ag's numbers are correct, it's roughly 50 times a better value than Hydroguard. And then the dosage sounds wrong!? Who has experience with either or both of these products, and what can you offer to clear this up? Thanks.

    Yep there's a lot of discussion about this out there, but I haven't heard back about results.
    On the dosage though, maybe Hydroguard's recommended usage is configured for hydroponics reservoirs, while GF fungicide had other uses in mind?

    I messaged the sales reps and they told me it's not to be used in dwc systems. I'd upload a picture but is not working. I spoke with a Florida sales rep

    These are quotes from a booklet they sent me though.

    Drench application: Mix 0.5 to 4.5 pints of Double NickelTM LC per 100 gallons of water and apply as a drench or coarse spray to soil or other growing media in pots, ats, plugs, trays, or planting beds, for control or suppression of soilborne diseases of seedlings, cuttings, bedding plants, and transplants (including vegetables and other transplanted food crops). Make rst applica- tion at or immediately before seeding, sticking, germination, or transplanting. Repeat applications every 14-28 days as needed. Transplants can be treated immediately before transplanting into eld soils to protect against damping- off and other diseases that reduce plant establishment.

    Chemigation: Mix 0.5 to 4.5 pints of Double NickelTM LC per 100 gallons of water and apply via drip, handheld, or sprinkler irrigation systems. Refer to “Chemigation Instructions” for more details.

    As well though there Is a table to I can't upload listing diseases it fights and root rot is definitely on there.
    But then...

    CHEMIGATION INSTRUCTIONS
    General information:
    Apply this product only through drip (trickle) irrigation (including micro-irrigation through spaghetti tubes or individual tubes) or sprinkler irrigation (including impact or microsprinklers, microjet, overhead boom, water gun, solid set, lateral move, end tow, side-roll, center pivot, or hand move, including mist-type systems); or with hand-held calibrated irrigation equipment (such as a hand-held wand with injector). Do not apply this product through any other type of irrigation system.
    Crop injury or lack of effectiveness can result from non-uniform distribution of treated water.

    It can probably be used in soil and as a dollar spray. Maybe someone will come by who has Experiance. I'll test it since I already have it when I transplant my next batch of clones. Here's the soil and foliage application info. It says as well it can be used for dampening off. 13$ for 16oz is worth a few test.

    Foliar application: For control of diseases on foliage, owers, fruit, or other above- ground parts of plants: Mix Double NickelTM LC in water and apply as a spray at a rate of 0.5 to 6 quarts of Double NickelTM LC per acre in suf cient water to achieve thorough coverage of the crop canopy with minimal runoff. Begin applications at crop emergence, transplanting, or when conditions are conducive to development of dis- ease. Repeat application every 3 to 10 days, or as needed, for as long as conditions favor disease development. Lower rates (0.5 to 3 quarts per acre) may be applied under light disease pressure, to smaller (e.g. newly-emerged) plants, or when Double NickelTM LC is used in a tank mix with other fungicides whose labels allow such use. Under moderate to severe disease pressure, or when environmental conditions and plant stage are conducive to rapid disease development, use higher label rates (3-6 quarts/acre), apply more frequently (every 3-7 days), and mix or rotate Double Nick- elTM LC with other fungicides for improved performance.

    Soil application: For control of soilborne diseases infecting seeds, seedlings, roots, crown, stems, or other plant parts below ground or in contact with soil: Apply Double NickelTM LC at 0.5 to 4.5 pints per acre. Mix the required amount in suf cient water to apply by one of the following methods:
    • Soil drench applied to transplants in ats or pots in the greenhouse or nursery any time prior to transplanting (see additional drench instructions under “Nurseries, greenhouses, shade houses, and ornamental plants” below).
    • Soil drench at transplanting, using a “water wheel” injector, spray nozzles/hoses, or other method to drench each root ball and/or planting hole.

      Soil or seedline drench, or banded spray (in-furrow) at planting. See the section on “Banded (in-furrow) application” below for additional instructions.
      • Follow-up (post-planting) preventative applications can be made every 2-4 weeks by one or more of the following methods, if needed:
        • Drip (trickle) or any type of sprinkler irrigation, any time after planting or transplant-

        Spray directly on soil surface and/or lower plant parts. If targeting root dis-

        ease, follow immediately with suf cient overhead sprinkler irrigation to move Double

        NickelTM LC to the root zone.
        • Injection directly into the rooting zone using shanks or similar equipment.

        Lower rates (0.5 to 2 pints of Double NickelTM LC per acre) may be applied under light disease pressure, to smaller plants, or when Double NickelTM LC is used in a tank mix with other fungicides whose labels allow such use. Under moderate to severe disease pressure, or when environmental conditions and plant stage are conducive to rapid disease development, use higher label rates (2 - 4.5 pints per acre), apply more frequently (every 2 weeks), and mix or rotate Double NickelTM LC with other fungicides for improved performance.

    An amazon comment said yes mix a rate of 1:20 water then add that at 1 ml per gallon.

    I've been using it in GH waterfarms for 2 grows now. works fine in dwc.

    @Jypsy Dog turned me on to it. i think he's using it in coco if i'm not mistaken and works fine for him too.

    i add about 2mL per waterfarm 2x a week if i remember

    Speaking of Southern Ag, they also make some well priced Spinosad and Pyrethrum concentrates :)

    Go to Amazon Read The Comments and you will get several people using similar methods to use this sucessfully as a hydroguard alternative.

    see post 6 in this thread.

    it's not an alternative, it's the same strain of good bacteria just way more concentrated

    Didn't catch it for some reason. Most conversions were (1:20= 1ml per gallon solution or 20ml to 1 gallon = 2ml a gallon solution.)

    Meaning if you mix 1 ml of S.ag to 20 ml water that can be used @ 1 ml per gallon so 1 ml of s.ag should cover 21 gallons of water.

    No matter which one you use. After treating the current rot problem you may need to lower your res temps some to prevent reoccurrence.
