Seen a couple of people having issues with gunk in the res and SM-90 lately.

When I run across them I will post links.

I believe it was Bobblehead and Mister D.

Yea i just mixed up a new batch for the veg room this morning...using only GH and sm-90.

Just checked and I have a cloudy frothy res???? It looks like somebody hocked a bunch of loogies in there. whats going on with that?

Just noticed that slime for the first time this run. Res temps have been a little higher than I like, but SM-90 and Silica are supposed to buffer for higher temps iirc. It has to be the oil in the SM-90 mixed with Drip Clean imo. I forgot to add the Drip Clean last couple of mixes (partly due to the nutes I am using are supposed to be high grade and not needing Drip Clean). I have been adding SM-90 religiously, but Drip Clean not so much. Maybe that is the connection?

Hmm i didnt put drip clean in.

OK, next lol...

Damn! Just found this thread. Room for one more to pull up a bucket and watch?? I am studying and plottin and scheming for my next run. It will be my first attempt at vert and this is much like what I want to do except I use Coco w drip to waste and not aero. I live where it is humid and aero in my exp keeps it to hard to keep RH levels in check.

LOVE the setup FHCat and many fat nuggetzz to come in your near future.

Peace! NugZ

And no ph up? Does the GH not require a ph adjustment? Ph up sometimes makes a cloud, there is a thread around here, I think in the infirmary where people been seeing the ph up clouding up and I believe they started adding it first (before nutes).

To be honest, I have seen the cloud too, just didn't seem to be a prob with coco.

The jar test I did yesterday:
The jar I added the drip clean last, still has a slight cloud at the bottom that remixes somewhat but leaves some really tiny white slimy floaters.
I would think this would be ok for the nozzles your running, especially after having been pushed through a screen (pre-filter).
Might fk with droplet size though, and no telling how effective the feed is when/if its slimed onto the roots in spots.
Im thinkin you want nice crisp cool clean nutes hittin them roots with nice fine droplets.

The jar with drip clean added first is a fkn mess!

So all we really learned is that it is obviously best to add the drip clean last with this scenario. BTW I was only using the label= .4ml

Maybe some of the additives could be used towards the end of the tank, after the ppm is lower?

I would go fkn jar test crazy and record the data until you get this one figured out. Do some tests adding stuff to the already spent juice too (last day or two before you change the rez).

Im hoping these are just the remaining issues you have to address to pull a nice 5-6 lb crop!
Maybe you can just source the active ingredient/s in sm-90 and work around this?

Thank you kind sir.

I got the same gunk that I am seeing in my res, in my aero cloner, and it gummed them up good. Whatever the cause of this you should figure it out. Clogged nozzles=failed nozzles...

Aero cloner<Aeroponic nozzles

Guys.....I usedta mix 200 gals at a time minimum and always used my additives last , but as Hazed has made note of , I made concentrated slurries in old GH jugs and let my tanks sit and buffer before ever turnin gate valves and releasin it to the plants.....and not once....ever...had cloudy shit , slime , or loogies form.....this shit`s new to me.....

Never used PH up in my life with GH nutes either , but Silicablast raises PH so I guess it was my adjuster that actually help the plants instead of just bein another variable in the equation of rez management,...

Somethin makes me think Nutrilife`s not makin their shit like they used to.....Coriander oil in suspension is all my jugs EVER said on my SM-90...dunno....

I HATE Hydro whore manufacturers.....always tryin to get more profit outta less product.....anyways....

I pray for ya`lls deliverance....Freds.........

Just to be clear, since everyone seems to be ignoring the fact that I have ONLY used GH micro, bloom, and some sulfuric acid as ph down. NO drip clean, sm-90, etc, and I still have the slime build up. Also have a gro bro running 300 blumats using nothing but micro, bloom, sulfuric acid, and sm-90. He is having ZERO problems with this combination. Got some jar testing in progress to see what that can tell me. I'll report back when I return from the grow.

Well......guess I missed that with my old timer`s disease Mr D.......so....

WTF ? ......Ran battery acid as my ph down for many many yrs , and ain`t got a clue where the slime`s comin from Bro.....but maybe I do....

SM-90 being an oil , and Dripclean bein some Euro-engineered secret fuckin formula just makes me lean toward the cloudiness side of the issue , but slime usually comes from elevated rez temps......and....

Since you`re runnin blumats and not fast hydro , I`m pretty sure yas`ll have no issues except havin ta clean the shit constantly for inline filter life.......

Still scratchin my head on these other issues though....

Peace....Freds.........

I believe it was Bobblehead and Mister D.

+1 here too....

DHF - Yea not sure what is causing it. My main res sits on a concrete floor which keeps it steady at 70 deg 24/7. I have my pump on mixing everything 24/7, and creating a waterfall for constant aeration. It's not bacterial in nature, or the hydrogen peroxide would have killed it. Res was clean when I got it, but I cleaned it again anyway. I'm not experiencing any cloudiness with just micro, bloom, and acid. After testing your advice and letting the micro/bloom mix for 24 hours before adding sm-90, no cloudiness anymore . I will figure this out, because it's unacceptable. Think i'll scrub the res again, and check every inch of pipe. Shit is coming from somewhere, and i'm pretty sure it's not my nutes or the acid. I'm using sm-90, and roots excell in veg with no noticable slime issues, but i'm hand watering until the table is full.

it's still possible to get a Bacterial Slime in a hydro res, plumbing and containers and troughs.... especially in recirculating hydro, that hydro environment is not only a great place to live for roots....

It's called Cyanobacteria... there's a lot of threads here in which is has been found to be a bacteria that also plagues Aquariums and Aquafarms, it needs light to survive apparently and it's a bitch to get rid of. I quit Aero because of it actually...

double post

Yea i hope we can figure this out. I would hate to have to replumb my whole system beacuse some gunk in the pipes. The sprayers are working fine. It takes alot to clog these sprayers. (I dont have a filter between the pump and the sprayers) The only filters in my system is the chiller pump in the res circulating 24/7 @ 1267 gph. Its powerful like a garden hose on high 3-4 inches above the water line constantly mixing and aerating the res.

So far so good with GH and sm-90 + ph down for (2 days). I pulled the chiller pump out and inspected, no gunk yet. I just now added drip clean at .4.

Also.. after mixing up the veg res yesterday (after finding the loogies) the res looks good today (no funk)

I'll look into cyanobacteria, but unless it's some super bacteria that can survive over 3x the plant safe dose of 35% peroxide I doubt this is my issue. Not ruling anything out though. Thanks for the input.

id applied 29% h2o2 at super high dosage rates as a last attempt to save this AeroFlo when plants were getting sick, it didn't do anything!!

i threw out the cuttings and poured in 4L of Bleach into a 40 gal res let it run for 24hrs and the stuff came back next time i tried to use the AeroFlo.... hate to be negative but the shit is like Hydro Herpes... once infected a system will always have it in it cause apparently the stuff is resistant to bleach now....

Do you run bleach through the system after each run? Bleach kills almost everything. Put on the rebreather and spray the shit out of everything to the point of killing everything in the room (except you and your rebreather). If it is strong enough to kill a human it should be more than strong enough to get rid of the slime.

Do you resuse your hydroton / rooting balls? I think reusing these products leads to huge problems. Bleached plastic and all new rockwool / root balls is a good place to start.
