Best way to combat pythium and root rot in all hydroponic growing methods.

[OGMMJ]

Update , added hydroguard and a dash of pondzyme to the Rez again today, EC is at .7
Right about 350 ppm, ph is a little higher then I would like at 6.2/6.3 been, it seems to be climbing about .1 or .2 every 24 hours I'm thinkin it might just be the nutes because I don't seem to have any slime coming back and all new root growth is white, since the new recipe with the addition of silica blast and pondzyme and hydroguard the roots are seeming to thicken up,

Moved my white widow big bud over to the vegger today as it was having some deficiencies so hoping that will finally take off with new green growth,

Checked my ph in my cloner today and it was 8.0! Yikes, did a change and washed with a bleach solution and did half tap half RO ph'd down to 6.5.

I would like to get my ph lower, ideally I'm shooting to run everything at one number, I picked 5.8, but I think I'm going to experience some climb just from these nutes, the bennies might be causing a slight rise as well? So I'm going to do a fresh res change again this weekend and ph everything down to 5.5 and let it climb and see if it continuously climbs or finds a number it's happy at.

Also another thing... I seem to get good root growth in my vegger but it seems to be all downward and not to many secondary roots? Anyone have any thoughts? I'm thinking about lengthening the off cycle of the sprayer to maybe 50 seconds on 7 or 8 minutes off

So they still look a bit fucked. Wonder if it's the light leaks that are around the edges? They are clumping and with mine that was a sure sign the roots were still on the verge of rot. Wonder if maybe just using the hydroguard might help. I was running tea when the rot hit . And yes even starting at a ph of 5.6 seemed to be fine for me and it would actually drop as time progressed. What's your Res temp and root chamber temps? Still lower than 70? I'm having good results at 66 but haven't tried higher.

Hey bud! Quickly back to help as always! Much appreciated!

Yeah the roots are still clumping but it doesn't seem to be as bad, the new roots don't seem to want to clump as much as the old roots that are just still clumped, I massaged the rotten mess today and the rotted roots are just falling apart at this point so I think the hydroguard and pondzyme is starting to break down the dead ones while the plant is replacing with new ones.

Rez temps good and root chamber good, res temp has been low with low weather outside lately, like 63, root chamber right where your at right about 65-66. I really won't know until I have an entirely fresh plant go through the system, which I have two seedlings in my cloner right now that have been introduced after my "cures" for the rot were implemented, so time will tell. As always.

I'll try and get a closer pic of the plant I chopped all the roots off of, that one shows that the new roots don't seem to be clumping as badly, another thing is I mentioned my roots are still just shooting straight down and I think that has something to do with the fact they seem to look clumped, also I'm wondering if they will just always kind of have that look seeing as it's a Stinkbud system and the water sprays on the roots and then runs down then and back into the top tote then waterfalls into the lower Rez, so the natural fall and weight of the water might cause the roots to just kinda hang like that, (opposed to dwc bucket where the roots have some buoyancy so be able to spider web each and every way) make sense? Just rambling stoned thoughts.

Ya I'm not sure??? My root chamber is not as deep as yours so they tend to grow into a big mat. And yup water fall here too into the lower chamber, actually two, my chiller discharge is also a water fall. I wish I kept track of spray times but didn't, at your stage I was probably every hour for 15 min (no cycle timer lol). Keep me posted and maybe a sprayer wizard will pop in . I'm just waiting to harvest and shut down for the summer, head outdoors where lights are free .

Nice yeah I'm not sure that even with ac I will be able to run my flower space, low outside temps lately and my root chamber still reaches 70, if it's 80 outside my Rez will hit 72, my hope is that if I can get the Bennie trick down I will be okay with my Rez maxing at 72-73 for an hour or so, (no chiller) although seeing as I'm only running a 15 gallon Rez I'm looking into getting one just for the flower room, but I also have dimmable ballast so maybe I can just turn the room down to 800 watts vs 1200 for the dog days of the summer to keep temps down just to keep the perpetual schedule going.

Currently have like 19 seeds germing in different methods so hopefully most of those will come through and I will be able to see how a new plant does and see if it shows any sign of rot.

It will be interesting to see the results with some new plants. My girls did recover but the cuttings were 10 fold better once it was all dialled in . I'm looking forward to getting stuff going outside .

 

[OGMMJ]

Yeah I hope I can get some decent sized veggin plants to send some clones outside, due to being behind I'm going to try to just send 20 or so clones outside around June and hopefully will be shorter easier maintainable bushes hopefully it works like that. I also have been recently building an outdoor hydro nft system for tomatoes and peppers and such. Little behind on that as well.

But yeah time will tell with the new seedling that's in there, see if those roots get infected, if they do I guess I'll pitch em or go ahead and throw them in soil and toss em outside.

Just hoping most the seeds I'm germing now root.

 

[OGMMJ]

Also threw in my 400 mh and took out the 250 CFL, I think the warmth might help, tent gets down to 60s at night like 59-60

June should be fine, June 1st is the typical planting date here anyways

Sounds like your growing in the same shed . My temps lights off temps get to 50's and lights on are kept no higher than 75. Well until it gets hot , hope not for a week or two .

Lol yeah mine is a stack stone basement lol, built a frame for my tent to stay off the floor but yeah my temps in the early morning were like 56

Honestly haven't notified any ill effects except maybe the leaves curling down. Could be other things though, honestly I would rather grow in 60 then 90 anyway

But then of course my flower room might as well be in the attic lol, top floor of the house with a false wall, plaster and lathe exterior walls not sure if your familiar but a pain all around, horrible insulation, huge mess when doing anything involving getting into the wall and been having a hard time even in only about 20sq feet with 9000 btu ac keeping it cooler then outside temps.

My leaves curl down when ph goes higher .

 

[OGMMJ]

My leaves curl down when ph goes higher .

Very possibly because my ph has been in the 6.1-6.3 range, I would like to start keeping everything at like 5.6-5.8 but waiting until I change the Rez this weekend

 

[OGMMJ]

My leaves curl down when ph goes higher .

Also unrelated but I have some concerns, my seedlings seem to literally take forrrreveer to start getting some nodes, think it's the low temperatures ? Like the one seedling has had its two little seedling leaves for like 4-5 days with no new growth. Only half RO half tap in the cloner. I'll check the ph in there when I get home.

 

[Budley Doright]

Just checked my last grow (the root rot one) and 10 days for two full nodes. But I used rock wool and peat pods. Then it went to shit lol.

 

[OGMMJ]

@Budley Doright good news! I believe I finally found my culprit for the infamous rot I have been dealing with!!

As mentioned that I would check the ph of my cloner when I got home.. Well I did and sure enough it's back up there at 8.0 like it was on Tuesday

I had to get an answer, so I proceeded to change the res again

last time I rinsed everything with bleach solution but I didn't run any through the system... There's the mistake, I popped open my pump and sure enough, bam! Brown slimey gooey gross dab lookin junk!

So I'm happy I found a reason for this rot other then all the other worries I was having, (if it was my RO storage, my water, my equipment) so needless to say I put an overwhelming amount of bleach in the bucket and soaked all the pieces of the pump for awhile and ran the sink through it for a few minutes letting it run through all my lines and such, letting it all soak as I write this, then going to put another heavy bleach solution in it and put it back together and let it run outside for 10 minutes or so, then fresh tap and RO water and hopefully no more rot troubles now that I have started using bennies as well!

Don't worry I took pics of the gross sludge

[Budley Doright]

It will be interesting to compare the ph readings now . I'm a newb to all of this hydro stuff as well . The way I've learned is through disaster mitigation, be it leaks, overflows, and yes rot lol. Probably not the preferred method but it works lol.

 

[Budley Doright]

How do you stop the roots from going into the bottom Res?

 

[Budley Doright]

Have a look at my Dr greenthumb oh zone thread, first page has a pic of one of my trays c/w spray heads. I have switched out the sprayer's to just straight flood and drain now though .
