Pythium Prevention

Hellraizer knows whats up, h202 is the tomahawk missile of anti-pathogens, bleach (which i never had to resort to) is the Napalm. h202 at 3 ml to the res every 3 days, 1ml everyday with top off. Rinse and clean with 15 mls of h202 every week, run plain water with 15 mls of h202 for 3 hours, rinse and re-boot with nutes. that all it took for me. i had some nasties despite of being under 68 degrees res, 75 ambient, with two stones per 5 gallons, and i swore on dm zone. wasn't Pythium, but it was similar, my girls are happy as a clam...."2-3 minutes", sure dude.

oh, and keep the zone, take the Zyme back (been there, done that, lost the crop anyway), and never go back to that freakin shop cause they raped you. Any one with basic knowledge knows all that stuff together is extreme overkill.

Chlorinated tap water works best for pythium. If I get an outbreak I change the resevoir every three days with chlorinated tap water, it works every time. The high production, commercial greenhouses (fruits and veggies) all use chlorine and chlorine alone to deal with pythium. H202 works, but not as well as chlorine.

Also, "floating white stuff" doesnt really sound like pythium. And with the nutrient soup your cooking you could be adding to the problem.

your 100% right just seems people are more apt to use H202 over adding bleach! I offer H202 as a option most of the time due to the fact
it works. but bleach is a win all, if the levels added are right. pool shock also is a good sorse of chlorine. just seems chlorine/bleach/pool shock
doesnt get the credit!

how much bleach do u add per gallon? and it wont effect the plants in anyway or leave a white residue?

I had root rot on my 1st grow and hygrozyme took care of it. I tried h202 before i tried the zyme and it did not work for ME. As far as bleach goes I wouldnt even consider putting bleach in my rez but I have never tried it so maybe it does work.

To each his own. I grow medicine. therefore I try to keep it as clean and as natural as possible. Hygrozyme is omri listed and a certified organic product.

I am not a total newb. I have been growing for about 2 1/2 years and harvest a crop every 2-3 weeks. I have learned everything I know by reading and trial/error. I used to post on RIU a lot but there are a lot of young bucks that seem to know it all and all they want to do is argue. That has driven me away for the most part but I still lurk and try to help someone out when I can.

I am from the D too. If you want help from a fellow patient feel free to PM me.

i am also curious about this, i had a bad algae prob thats been raping my plants in the ass, but i finally found the light leaks which was causing this. the h202 did work for me in killing the algae in the res but didnt do anything for my aeroponic unit itself (pvc and sprayers) i had to take it all apart and use bleach water and scrub real good. anyway i would say to take care of ur problem, check ur roots for rot. if they dont look nice and white or at least healthy and arent growing u should cut them off(the deal ones)also, when i do this i dip in a rooting hormone . make 100000% sure there is not even one light leak because with water+nutes+good light= algae= pythium. and make sure ur temps are in range and u should be okay

as long as you do 7 eye droper drops per gal. of plain uncented bleach you will be safe. add back every three days with bleach, and you
cant taste it or affect the burn either.

Looks like I'm gonna give some bleach a try. It seems to be not going away. Thanks for the help Hellraizer.
I think I'm gonna go with coco in my future runs.

My res temp is 64-69 degrees and my box temp gets to about 76-78 degrees during its hottest time. I'm not liking this hydro upkeep. I hate not succeeding at something, this is getting frustrating.

well a chiller is in order it sounds like, that would take care of the temps, hydro is a beast to tame in a warm areas

Hey Hellraizer, what do you recommend I use from my nut lineup to combat this shit, you know your shit thats why I'm asking? I'm in my 3rd week flower.
Advanced Nutrients
SensiBloom A/B
VooDoo Juice
B-52
CarboLoad
BigBud
BudCandy
Sensizym (in the mail, should have Tues.-Wed.)

Dutch Master Gold Range Zone

H2O2(30%)

Assimilator from Flora Hydroponics?(shop didn't have Hygrozyme and said the rep said it was comparable)

Bleach

Any suggestions to add or change?

I would use AN three part with bigbud/budcandy/b52/overdrive and thats it. no voodoo or zym
reason I say that is the H202 will kill all the bennys in those products. use alot of air to help cool the
water. zone works like bleach in a way, it says its a root conditioner. with super high water temps
nothing listed above is going to be 100% I would freeze 1 gal jugs of water if a chiller is out of the
price range

hey hell, i read somewhere that if you use a small amount (1.5ml per gal) it will destroy minimal amounts of "zone". i finally figured out what i had. it was algea. a very thin layer of it. i just assumed it was a film from the massive amounts i use for these monsters. that why my ph was fucked up, but my roots were fine. anyways, h202 doesnt seem to have as much effect on algea as the zone does. when i added 5mls h202 to my 5 gal res, nada. when i added zone it foam like crazy, as if it were attacking the algea. now my ph is stabilizing. i could tell it wasnt the zone reacting to the h202 because the amount of foam coincided with the amount of algae in the res.

I've tried zone and it never foamed and I know there was bacteria in the res. I've never had h202 foam either.
Do a test put a gal. With the rite h202 in it then add zone see what happens then you will know

thx. do u have any pics of before using bleach and after? oh i noticed i have some greenish looking balls also growing on the roots do u think bleach will help with that also?

The green is algae use a 3ml per gal mix and spray the surface of the rock this will kill it, but keep in mind
The algae is harmless. As for pics i never documented the before or after

Best treat for pythium is Bleach. 8 drops per gallon to decontaminate your drinking water, but 2 drops per will prevent any pythium infection, and 4 will usually clear any pre-existing infections.

It doesn't hurt the plants, and it always works.
