SAG really isn't all that people crack it up to be for treating water. Too much build up of dead colonies. Mix that buildup with you not changing water and your gonna end up with sludge on everything. Give it a go you'll see....... As far as changing water in your dwc? I think it's important, you can only top off so much before it starts getting nasty, discolored, just yuk in there lol. I'm kinda anal to though, I clean my reservoirs every week. Drain what's left and bleach them..... Your better off paying the extra 20 for hydrogaurd though, SAG simply put isn't made for this application. Run it long enough and you'll see why.
Interesting, I will be monitoring closely to see whether I go for the WC or not. One of my reservoirs actually kept itself super clean and nice for a whole month.

Is this root rot? Am I having an issue? If it is root rot can I fix it with h2o2 baths? The only other issue I have is high temps that I cant control. Also, just added Southern AG GFF

I just want to report that I have been using 1ml of SAG GFF mixed with 20ml of water and applying that mix at 1ml/gal to my 6gal DWC reservoirs and have had ZERO slime problems with temps between 68-78F (night day) AND changing the water/fertilizing mix in my reservoirs not every week but EVERY MONTH with minimal cleaning (just pressurizing some water on the walls and air stones.
Plants look good, roots are clean, so yes, I believe it works or I'm just extremely lucky.

How did this end up working out for you?

hello i'm new on the forum, i read all 29 pages .. very interesting. Here in Europe we unfortunately have neither Hydroguard nor GFF, so I was thinking of recovering the famous bacillus amyloliquefaciens on Alibaba, they are all powder products so go figure out the doses. I found a liquid formulation product in Italy, it is not for free sale but you might be able to buy it anyway. I wanted to ask if any of you are able to give me a hand on a possible dosage calculation, I try to link the product sheet below. If any European grower had other alternatives it would help

Finally made it to the end. DWC WAR 1-3 biological warfare, geesh what a battle

If anyone doesn't want to grab a chiller I recommend going sterile ( uc roots or pool shock) but honestly water temp is very important. The whole point of dwc is allowing the plant to get easy access to everything, thats including oxygen. Colder water holds way more oxygen I have ran sterile and with bennies and got the same results as long as my DO levels were adequate.

Hi everyone!

This thread has convinced me to give GFF a go. Some is arriving today and I need some experienced direction on a couple of uncertainties I have.

First and maybe easiest, after all this time would you experienced veterans still use 2ml per, or is the 1ml proven more sufficient. I don’t want to have an overload, but I want to protect what’s left of my root zone.

Also, Is this something I should use EVERY gallon of water I give my girls, or just once weekly, or even just when I flush (which is about every 15 days)? I wish there was a way I could measure so I didn’t have to ask these questions, but I need help understanding how to keep the right amount present on a long term basis.

Lastly, I use lava stones in my sump area to act as a filter to keep my water pump cleaned a little bit better, and also in hopes bacteria will colonize the rock and help keep any bad bacteria shock at bay during a flush. I’ve learned in time it’s a bad idea to only have bacteria in your water column, and then suck it all out. Anyway, the question is, will this baccillius amylol… also colonize the stone or do they just stay suspended in the water column?

I apologize if any of these are already answered, i know how annoying that is! I will read this whole thing through as I get time, so If it’s already been said.. my apologies!

Once weekly is perfect, unless you are treating an existing problem-in soil/soilless grows. Actually, I'm not sure what the best use of it would be in like a DWC system, I haven't looked into that in a long time. What media are you using exactly, I saw that you have a sump, so some kind of hydro?...I'm not sure if it will colonize under water, if that's what you mean, but it will colonize any media you use that gets plenty of oxygen. It's an awesome product, and the best value for rhizobacteria. Be sure to use it as a foliar regularly during veg too.
 
Hey man, Thanks for taking the time to reply!

Yes I’m using hydro, my own little frankenstein system that I’ve developed over the years.

So the bacillius only live on the surface? I had hoped they would also attach to the lava rock under the water line. My whole reason for the lava rock is to give good bacteria a place to thrive, and of course help filter the water for the pump.
 
I need to clarify if I’m mixing it improperly or not. When I mix up the BA with water, I use a Pepsi bottle (16oz) as the new container, and then pull my 2ml from there. I’m concerned about how long the BA will live in that Pepsi bottle especially with the cap on. With my setup It will probably take a month to a month and a half to use up that Pepsi bottle before I’m ready to make another batch. Does anyone know if the BA will survive in the Pepsi bottle that long? I could use a smaller container if necessary, but these little bottles fit perfect on my shelf so I’ve got all my liquids labeled and stored in them. I would appreciate your opinions.

I would also like to add my experience so far in case anyone here is reading this thread in search of help. So far I am seeing big improvements with the addition of this to my regimen. Never had bone white roots before, even now I have the old stained yellow sickly looking roots I’ve always had but now with brand new bone white roots emerging everywhere! I definitely think this stuff is helping as I’m seeing changes I’ve never seen in my setup. No more “sweet” smell of the bad bacteria that seems to bloom every time I flush, no new rot, even with partially rotted mass already, plants look great, are drinking, and for the first time decimating the ppms. I may not have figured out the perfect water parameters, but I feel I’m at least in a good neighborhood for the first time. I’m looking forward to seeing where this goes.

After all that I’m gonna remind you of my question lol.. Can BA survive in a sealed 16oz bottle for a maximum of 2 months? Or is it necessary to shrink the container?

Thanks all!

i've been looking for that information, and it is surprisingly hard to find.
i would think 4 to 5 days would be the longest it could be premixed, the bacillus is in "suspended animation" in the container, when you mix it with water, it reactivates it, and it needs to start eating something to stay alive...if you don't use it up before the "food" stored in it's medium is used up, it will starve. you could possibly use something like molasses to "feed" it, but i have no idea what would be the right amount...
i'm curious myself now, i'm going to keep looking, i'll let you know if i find something useful

(still can't find it...i directly enquired at southern ags "ask us" page, waiting on a reply)

I’m glad I’m not alone in the dark. I don’t mind the work to find out but I’ll take any shortcuts learning from others I can find! I’ll be glad to hear what they have to say! Thanks!

Regular shelf life is around 2 years stored properly, we recommend you only mix what you're going to use. Because of different pH's and minerals in the water, you can't guarantee how strong the mixture will last once mixed and sits .

that's their reply, only mix what you're going to use at one time, which has always been my practice, anyway.
 
Good! I like that idea better. It makes more sense to me. I’m honestly surprised you got a real answer, last I heard they were taking the “not designed for hydroponics” route on inquires. Thank you for taking the time to hit the source directly and then sharing the results!

After I made that first post I decided to dump my Pepsi bottle of mixed product and calculate the amount needed but per gallon and just add it directly. You could see some settling had occurred as the bottom of the bottle was much darker. I jokingly said to myself, yep look at all that dead bacteria lol.

Now, (if I’ve done my math correctly) I came up with .1 ml per gallon. For my case 1/2 ml per 5 gallons. I started that amount about 3 days ago. I’ll post back if I can tell any difference. Then again I guess the only way I’m gonna notice a difference is if I’ve overdone it and get that bloomy film referenced earlier in this thread.

I will say that so far I’m still convinced the addition of the bacteria has had positive results in the quality of my water. My roots are becoming bone white. Something I’ve aimed for but never really been lucky enough to have. I’ve also recently been using baking soda in my water, not to raise the ph, but to add alkalinity to the water. I actually have to ph back down once I get my desired alkalinity level. Before, I’ve struggled with root health and I suspect it was due to the acidic conditions I couldn’t ever get stabilized using RO. Now with the addition of the baking soda I can literally go 5-6 days and my ph hasn’t drifted enough to be requiring any adjustment. I couldn’t even go 24 hours before! I do want to add that I avoid sodium problems by flushing every 10-14 days, but I don’t flush specifically because of the sodium, I flush frequently because look at that nasty ass 2 week old water.. gross lol. I wouldn’t want to drink that shit either!

Anyways I appreciate the answer, it definitely gives me more confidence on direct mixing what’s needed instead of premixing a supply.
