Hi,

this is my first aeroponic grow I been growing in soil for a few years and some grows with dwc never had an issue this bad.
I germinated the seeds in aerogarden with no problems but I guess I transplanted them too late so the roots get touched and exposed because I couldn't get them through the net pot holes so I guess they got contaminated.

They are 12 days old but look very behind and are autos :wall: 2 days ago I put 5ppms per gallon bleach into the water but no change until now so Im not sure to quit the girls or give them some more time......

water temp is around 64-68F and ph stable at 5.8 with RO water 200ppms calmag, silica and GHE tripart ferts all 500ppms...

That system is going to be the cause of so many problems as you see now and later on.
they need top watering till theres plenty of roots
spray emmiters will only wet the outside of the hydrotron
DWC works totally different is a very active system and will not give problems when running right

Ignore harry. He has no clue about aero. At all.

Root rot is really tough to kill once it is establish, so you may well have to dump them all, but it is worth trying for a while longer I think.

I have questions though.

Are you recirculating or drain to waste?

Either way, dump the rez and clean it with strong bleach, rince, then refill, but keep the PPM low. Maybe even just tap water until they start to recover.

If there are sections of the roots that are really soft and pull off easily, do so. It is better to get rid of as much as you can. This will stunt the plants, but might let you save them.

Raise the chlorine to 10 PPM for 24-36 hours, then drop back to 5 PPM. I would also top water the hydroton with that strong solution. The bacteria is going to be in there too and your spray might not reach it well. Dont worry about over watering - you cant over water in hydro as long as the water is aerated.

5PPM chlorine is a safe maintenance level, but its never worked for me when trying to kill an established infection. Even 10 PPM may not work, but its worth a shot. It might burn the roots some, but thats still better than the plant going in the trash. The roots will recover if you kill the bacteria.

Im curious - are you trying to run this as NFT or LPA or HPA?

Im afraid your root chambers are going to end up way too small no matter which option though. Even autos will grow roots to fill a pretty big volume.

Im currently running 3 autos in an air atomized aero setup with a 56 gallon root chamber and its more than 1/3 full with roots and I still have a few weeks to go.

thanks a lot for the detailed answer!!

i dumped the girls today I lost too much time and the end result wouldn't have been worth it.
I germinated some new seeds and give it another try and would appreciate some advice.

When do you put the rockwool cubes into the system. I use ghe aeroflo10 is a recirculating aeroponic/nft system.
There is a riser at the end of the each container to rise or lower the water level but when they get wet there is no way to move them so I have to
leave them 1-2cm above so my water level is 1-2cm and there is big gap between the bottom of the net pots and the water but the sprayers splash some water on one side of the net pots. Do you think that is enough water until the roots reach the water or hand water from top and would you recommend to use bleach at 5ppm from the beginning as a precaution even If I don't have problems with water temp?

Rockwool is tricky as mentioned, I used to grow in AeroFlo´s before I made my own pipes. See my link. eg.

2-4 cm water level below the netpots is fine, in my experience the closer they are to the water level with rockwool the more often the cubes get too wet. Just make sure you hand water them in the beginning until the roots touch the water. From experience I stick to 3 cm to avoid a to wet medium.

how did you like that aeroflo? i've seen alot of good grows with them: plants need to be fairly compact though??

I think they are good,especially beacuse you could go directly from rooted clones into flower and have plants with a height of 80-90 cm.

Back in the Oergrow.com days I started out with an AF14 and bought more pipes to have 35 plants under 2 x 600 watt HPS, they had to have nets on both sides to keep them in line.

After a few years when I moved and sold the system, I didnt grow for a while and when I started up again, I made my own, hence you can customise such a system better then the OG Aeroflo´s .

Sadly I dont have any picures from back then.

This guy knows all. I did some experiments with him and sterile res. We used pool bleach hitting it every other day.

Your saying you have noticed a difference in 2 days I would think that would take a week when I was doing this before.

I have serious problems with this system. Issues I never had before with dwc.

the roots of my new grow looks strange very long lonely root without the hairs and the plants look droopy and the leaves are wavey.

im not sure but I think they don’t like water being sprayed on them all the time but I’m not sure...maybe is the beginning of root rot again because the roots looks slimey but my temps and ph ec is on point.

perhaps light is getting through the clay pebbles? Is the slime greenish? Maybe make some light proof caps.
Maybe the root riot starters are getting too wet/ too dry? Something died off and rotted in the system?
When i made an aero cloner the pump was on for a minute and off for 6 or 7 if I remember correctly

Yes but I’m not sure if it’s root rot I will post some pics later on. I used 3,5ml bleach on 50l water 3 days ago no improvement but i brewing some tea with mycorrmax from tnc. Mycorrhydro is not available at the Moment

so here are some pics I transplanted the seedlings last Sunday into the system 1-2 days after the germinated.

My ec ph and temps are good the problem is definitely somewhere else. I used 3,5ml bleach 3 days ago but im not even sure if it is root rot but the roots look strange and slimy maybe. On the pics the brown spots are mycorrmax not root rot I dipped them into the powder few hours ago.

Im brewing a tea with mycorrmax 2 teaspoons in a sock in 6l ro water. Im not sure how much of that tea I have to pour into my tank I also bought a Biofilter for the tank without carbon and put 2 big ass air stones in the tank....I don't know what else to do.

Light leaks might be a problem because the aeroflo tank is open there is just a cover in the middle and on the sides its open but the "rails" are covering it still there is a tiny slot on the sides but there is shadow no light...
