using bleach

well sumbitch. Fucking root aphids are back. Guess I'm gonna have to get out the big guns.

Leslie's has monopersulfate as the active ingredient. I tried to find something about its use/effects in hydroponics, but didn't get much. in pools, it's iused to "leverage" low chlorine/chloride concentrations into a good antiseptic that isn't very chlorine-stinky.

I skimmed this but could not find the bit where they discussed the monopersulfate (brand name Virkon). cn

that sucks. when i got root aphids about a year ago i used evergreen & it knocked them out. I applied as a root drench (soak) and also sprayed (plants, room, everything). i didnt have a prob with them coming back even tho there were flyers by the time i saw them. i did however reapply several times the first two weeks then @ once a month for a couple months. now i use it once in when i pot clones and right before i flip. im wondering if the chlor and uv filter broke it down faster than normal.

Bear; I liked where it read sodium hypochlorite was 100% effective for elimination of pyth. At least we are not the only people who think it is acceptable to run it. Nice find. I skimmed bout the first 4 pages. I'll peruse it when I'm a little more rested.

My root rot prob. is slowly getting better. My smaller plants have crazy root growth coming on. My mothers finally have nice white roots shooting out of their 10 inch netpots. So I am real happy bout all this. I was gonna do a drench tomorrow for the fungus gnats with the gnatrol in veg and azaguard in flower. As the fungus gnats are still present. I put some new sticky cards out and got around a dozen willing customers on each in 24 hours. Now that I saw some root aphids I think I'm gonna hit my veg with the Imidacloprid. I was hoping not to use this stuff. Got some of the best roots I've seen in months and now have to use a new poison not happy at all.

at least I get to try out my new mask.

I'll probably go ahead and use the azaguard in flower tho.

Did you adjust the ph of your drench before use? I didn't last time I think I will next.

I cured my bacterial infection using 1ml of bleach per gallon... Took about 2 days but now the foam which had been building around the edges of the cultivation tubs is now gone and I've noticed root growth has resumed. I was observing rapid root growth before this infection and then it just completely stopped - until now. I am still trying to figure out exactly what this bacteria is and what caused it. I think it is a type of cyanobacteria but I'm not certain. Also, not certain what caused it but I'm wondering if it isn't from excess silica. I know the effects of the bacteria but now I need to know the cause.

I'm using a water treatment to remove the chlorine/chloramines before adding in my Great White bennie tea as I don't want to continue using bleach... At least for this point in time until I do more research.

i am curious about this as well. My problems coincided with the use of protekt to an extent. There were a few other variables at the time as well tho. I have not heard of excess silica contributing to slime infections before.

I believe what I am battling is pyth. The link bear put up gives a pretty good description of what I am dealing with.

i adjust the ph before i add the evergreen after nutes. the first time i used a big tub and a pond pump with a watering wand attatched. set the plants so the top of the soil was like 6 in above the water line and just drencged it top to bottom for a bit (no nutes that time. after that i just add to the res + spray. i think the pyrethrum is a repellent as well so they will get out of the soil if you do a drench. thats why i spray same time. i'm not shure who i saw doing it first db or someone on youtube, but i got a $20 paint sprayer from harbor freight for spraying the room down. it hits everything np. realy small drops. oh i add a drop of dish soap to break the surface tension too. hth

My problems started while using Pro-Tekt, too...

well, did a drench w/the imid in veg. last nite. @.44ml/gallon for the root aphids. Running my sulfur burner in flower today. I'm gonna give it a good 4 hour burn. This should help some w/the gnats and kill any errant spores in my room. I may do a drench w/azamax in flower tonite. I dunno yet.

I have been using 4oz 35% h202/50 gallons a day for the last 4 days in my flower rez's this is keeping the slime at bay. Gonna drop back to
3 oz today

just a hint of slime in flower rez 1 this morning apparently 3oz/h202 not quite enough. Final flower rez. looks good though. Veg rez. still looking great.

Did the drench with imid in veg. Found a few dead aphids and a few dead fungus gnat larvae. I am hoping the imid helps with the gnat larvae too. They are not listed as a target species on the label tho. I put a few new sticky traps out so we'll see how many customers I get.

I put a drainage mat down in my homemade trays to help facilitate drainage and such. It is gonna be the ticket I believe. Kinda pricey but I gots to do what I gots to do. Room is not big enough to go with store bought trays otherwise I would. I am getting a storebought tray for veg tho.

Gonna do the azamax drench in flower tonite. Running my sulfur burner in veg now.

H2O2 did nothing for my brown algae slime. Bleach at 1ml/g does the trick, though. Will cut back to 1ml/3g on next dosing.

It's not brown more white/clear

Same with mine. It starts off as brown but can be clear or clear with brown spots around in it. Has a jellyfish-like appearance in the water and has the same type of texture/feel. Covers the roots first as a clear slime but then changes to brown.

Any of that sound familiar? Would love to know if you've got the same thing. Can you snap a pic? I would LOVE to know exactly what this shit is and where it can come from.

Sounds pretty close.

I believe it is pyth.

Read the link bear put up.

That study describes it and it's symptoms accurately.

Weird... I will have to read that article. All I know is that bleach kicked its ass and the plants recovered in 2 days.

I'ma have to go back to the bleach which is fine. I feel I should be able to run a much lower dose this time. The slime is just barely noticeable and only in one rez so far. Where a few weeks ago it was out of control. Interestingly it is only in the first res in flower. Which reinforces why I really need to get my new flood table ordered for veg but the hystore isn't placing another order to their distributor till next week. Oh well. things are looking better anyways with only flooding 1x/2days.

Funny thing is I have been running these same tables for three years with relatively few problems. Now root problems are an issue because my new minisplit is keeping it so much cooler I didn't adjust my watering schedule accordingly. I would never have thought I could get away with one flood every two days in 6 inch pots. The 10 inch netpots my moms are in sure but never 6 inch.

Amazing what good a/c will do.

Either way I have to get the flower trays draining better so I'm gonna put the rest of my mats in since they just got here. Prob. change water again tomorrow w/bleach in res1 oh, and azamax drench for flower tonite. so when I change water it will be fresh for next flood.

Word. I spent 2hrs today flushing my system out and then re-fill and pH/nutes... Turned chiller down to 65f and added 20ml bleach for 23g of h2o. Really wishing I had a hose that I could run to dwc system. Would make flushing, cleaning and re-fill sooo much easier. The water gets pumped out to drain in the tub but then I have to run back and forth with 5g buckets to flush and re-fill.

So what I've got going on is good ol' fashion root rot... When I transplanted from soil to DWC, I tried to keep as many of the existing intact roots in place... They came out as a bundle, like a long ponytail all wrapped together. I coiled them around the bottom of the net pot and apparently now they aren't too happy. Most of those old roots are dead or dying and rotting away, while the plants have put out new roots. Unfortunately I cannot really remove the old roots because they're entangled with new roots. I'm just gonna keep running the bleach until this all clears out and hope for the best.

After I flushed yesterday I dosed with 10ml of bleach and today I dosed again with 23ml of bleach... Back to 1ml/g. Just purchased some Dutch Master Zone online. It's chloramine based so it'll stay in solution longer than the chlorine and is safer. I probably should've just went to Wal-Mart and bought some Pool Shock or something that is primarily chloramine based but the DM Zone was $20 and free shipping on eBay.

I was thinking about mixing in some SM-90, but since I don't have a chlorine tester I need to be able to smell if there is chlorine still left in solution.

smell is not a good indication of chlorine concentration, heres why. bleach (sodium hypochlorite), and pool chlorine (theres like 3-4 different chems used as chlorine for pools) dont have a particularly strong chlorine smell. when it's in a pool (or res) it reacts with organic material (usualy something with n like protiens or ammonia) and forms nitromines. niromines stink like chlorine and arent as efficient as sanitizers (they do stay in solution alot longer tho). when your doing a pool route and ppl complain about too much chlorine hurting their eyes, (generaly right @ the time algae starts showing up), the way you fix it is to shock the pool. eg. you add more chlorine -raise the avail chlorine lvls at least 10x higher than the nitromine lvls. what that does is cause the amonia to turn to a gas and come out of solution. ppl usualy think theres less chlorine the day after you shock a pool bc it doesnt smell or burn their eyes. of course its not true there's way more. yoiu need 2 different tests to tell how much chlorine there is. personaly i would avoid any organic material in the res (also any amonia or urea based n) while you are using chlorine as it will significantly reduce the effect of the chlorine as a sanitizer. hth & gl
