ok so I finally figured out why I cannot source hydroguard in audtralia, and it is because BAYER, stupid, scum, and the government being dumb.
so along my search for hydroguard or a replacement, I found the intellectual patent for a product of theirs “serenade”,
essentially they copywrited the bacteria strain bacillus amyloliquefaciens
not only can you not sell it as bacillus amyloliquefaciens, you cannot advertise as “bio fungicide” with any of the other bacteria either.
what a joke.
Kettle
Try Great White beneficial fungi and bacteria, available on ebay, hint offer the seller $45 for the 150g and $150 for the 750g and he will accept.
@FrostyBuds, that’s not a bad price.
its not the point how can you copywrite a species, they didn’t make it… so I can but metric tones of biological species from Alibaba but I cant order a reputable supplier in the product I want, so the hydro# edge I thought was going to get me out of trouble just got them and they were 250ml bottles, I got 2 but I thought they were 1ltre, so its 120$ a litre, because its kinda a black market… because Bay$er doesn’t just sell to the general public.
it is a joke, it was discovered in 1943 by a jap scientist not bayer.
I use to work for them in one of their chemical plants and I do know they sell the identical product under different names, at different prices…
its shit… this rant will continue, I will go through all of bayers documentation work out what u can use hydroguard for.
LIKE; you may be able to use hydroguard as a preventative to molds so bud rot., but I need to reed more,
I am so pissed as u can tell.
more information from another supplier of the bacteria, re fungus. and how it works.
The active ingredient in Serifel® is bacillus amyloliquefaciens strain MBI600 (min 5.5 x 10^10 cfu/g). Serifel forms a ‘shield of protection’ against a broad spectrum of plant pathogens using three modes of action: competition for space, competition for sustenance and the production of antifungal metabolites.
When the Serifel spores are the first to occupy the limited space on the plant, they physically exclude plant pathogens from occupying the same space. Serifel then depletes the supply of nutrients available to the pathogen spores on the plant surface, causing any pathogen spores on the plant surface to die. The antifungal metabolites produced by Serifel, surfactin and iturin, penetrate pathogen cell membranes, disrupting cell function and causing cell death on the plant’s surface.
It is critical Serifel is used preventatively rather than curatively because Serifel cannot eliminate pathogen spores that have already infiltrated the plant’s surface.
ok so I know this is probably not really going to get read by too many people, but I find it interesting so maybe someone will.
ok I now know how to do DWC in Australia with no dramas, u sell your soul and buy the bayer product… its bacillus amyloliquefaciens plus Diatomaceaous earth, and starch I assume for food… and it is in wettable powder form in 10 pound amounts… and cost (apart from your soul), $330 aud or around 275 usd. it seems like a lot but you never need to worry about hydroguard for the rest of your life…
I don’t know im torn, I only want like a kilo… that would be enough the dilution rates are so low…
hope you all are well…
an interesting read of what the bacteria can be used for.
ok its been done, my soul is forfeit… ive ordered the bayer serenade opti 5kgs…
did I tell you I found out they bought Monsanto a couple of years ago… 
at least I know it will be good…,.
so it was $300 for 5kgs, and what is it? the other ingredients are starch and Damascus earth…

why I went with this? I am not anti hydroguard, im pro hydroguard, we just cant use it in Australia, hydroguard doesn’t smell, I bet this stuff does… use hydroguard if u can
the product I believe is 100x more concentrated then hydroguard, its stable… I can get serenade prime, its liquid form for half price for twice as much… but its 10 times less strong, hence 5 times more expensive… confusing? 
its also liquid, and in a 2.5 gallon amount, im never going to use that all in time… it separates… the bacteria dies… it seemed cheaper, but the guy at the agricultural shop was SUPER helpful, and we both agreed bayer is the devil and the product I brought is perfect for preventing root rot in my medium sized ‘aquaponics’ system… 
what im going to do is measure out 500 gram amounts in new sterile plastic jars, then vacuum seal each one… id say that’s root protection for ten years for all my systems at least… now $300 dollars doesn’t seem too bad.
ill let you know how I go though…
