HELP - ARRRRGGHHHH - Pythium Again !!!!!!, Tried everything !!!!

[jm420]

also if your nutes are organic based that can also lead to probs in dwc and rdwc

 

[Madrus Rose]

Well i have UV sterilizer on the way but after above it seems pointless if doing res changes as i should have...

People must use them on here to good effect, or do i just do as Madrus mentioned ?
But i see the only benefit of this is that you sterilize the small amount of solution left in the system before replacing it...

More confused now...lol

Well , its for sterilizing the entire system running at full capacity . Would always suggest switching to a larger rez anyways , rule of thumb for E&F for example would be 50gals for 4x8ft table which with larger growing plants is a bare minimum . It would take a 15watt UV treatment of just an hr or so to sterilize 50gals 100% . I would go larger even 100gals which makes for even less tweaking the nutes & less work .

Even with proper rez changes am assuming some still have problems with brown slimes in nute rez & root problems , UV treatment makes that almost impossible for kills all & any of the bacteria that cause this . Its so easy just flip a switch on the UV unit once a week if only 2hrs etc , totally preventative ...and fear of pythium/slime a thing of the past . Just use 1hr two times a week , this wont effect the nutes at all , imo.

* actually "kills" the bacteria is not exactly accurate , it completely destroys the bacteria's ability to reproduce disrupting the DNA .

 

[jm420]

I just noticed you are using hygro zyme. that will and does cause big time probs,get rid of that asap .it just feeds the nasties

 

[jm420]

IMO uv sterilizers and the such is going to make your problems worse ,
get back to the basics KISS
my guess is your nute regimin.I may be wrong
but I do know temps are the biggest cause you have a chiller so count that out,everythings clean and dissinfected count that out

so IME the next logical step is nutes

just for shits and giggles run LUCAS no additives0-5-10 for veg ph 5.8- 6.0 see what happens .

you cant be serious
Great reading on the hopper is about it IMO

 

[Madrus Rose]

Erik is spot on with most everything have read from him in years ...

High Times----> is what u want for the Loo ,
just Ask Ed !

Hey , why don't u read the article first ,
u'll be more well informed ? Covers the boards :

urban gardener has a graet article on gurilla growing to

 

[jm420]

I'm a subscriber (iget it free at the hydro store ) Its good reading for a crap in the morning thats about it .
Thares way more exp. here than erik has growing mj .I'm sure if i wanted to grow lettuce he would be the man to ask

you said it your self "most"
my guess is eric is wrong on a uv sterilizer

 

[Madrus Rose]

urban gardener has a great article on gurilla growing to

Someone mentioned the Brown Dirt Warrior (friends with Urban gardner) too, as an authority for guerilla growing yesterday on Utube ....
http://www.youtube.com/watch?v=9_N4nhYDmj0&feature=&p=F9D241CA0E177F96&index=0&playnext=1

Guy has some cajones i'll give him that ....but that type of
guerilla farming went out in the 70's & 80's ...at least
here in norcal , lol.

What i learned from this Canadian's Utube vids is how to get a
slipped disc & hernia in one fell swoop & become disabled for the
rest of my life , canadians sometimes really crack me up !

* hav a good one , read that article by eric from Maximum Yield tho,
really covers the whole spectrum

reggae on .

Well the point he's making in the article is simply many large aggy DWC growers hav been turning to UV sterilizing for care & control of their water/nute supplys. Whether u like the mag or not ...its still a fact of what they (large lettuce water culture growers) are doing .

Digress , ignore & why not just pass a doobie go drink a few beers & fall down ...just giving u one very nice ez solution to a cleaner rez
without pythium & brown slime & chances of root rot .

Otherwise just change out your rez frequently then & pass the
doobie ! Who cares ? Have fun !

 

[jm420]

all I"m gonna say is KISS and not my ass


ask erik for growing lettuce ,ask IC mag for the answers you need

 

[greenmatter]

eazy you are already running a chiller and h2o2 ..... while i agree with madrus about what uv can do for you i agree with 420 in the fact that that is probably not the problem. sound like you have a pretty solid system for your third grow. are you running RO? if you are i would almost bet you Ca is the problem. whats the ppm of your tap water? read about the effect of calcium on the root system. one of the things it does is protect the roots from pathogens AND a deficiency would look like rot. KISS. a calcium additive will cost you a fraction of what the uv system will and you can do that fast. meanwhile read something about uv systems, they work but they also have issues (and some of them are things you better know before you run out and buy one i.e.SAFETY ) the so called "liquid calcium" additives are not expensive. technology is cool but it is not always the answer.

my two cents. i never change the water all the way thru. weather its a 8 week indie or a 14 week haze. i keep my water at 64 degrees. i also run 12 inch air stones and use dutch master gold range. i do not use zone or hydrogen peroxide. i run an ro unit and top off with fresh nutes when needed. my experience when you change the water often and its not exactly as the water your changing out you will shock the whole system. so in an eight week cycle your basically loosing a week to shock resulting in major losses in weight and quality. my best yield to date running a cut of the pog was 13 1/2 pounds with six plants and 6k of light. cold water is the key to keeping pathogens at bay. between cycles i use a gallon of hydrogen peroxide 35% and run it for a day and replant. never in 10 plus years have i experienced any pathogens, period. cheers

do you here what uptown is saying. COLD water!! and you have that covered. KISS


uptown.... 13 1/2 off 6 ?????

 

[Madrus Rose]

do you hear what uptown is saying. COLD water!! and you have that covered. KISS

uptown.... 13 1/2 off 6 ?????

think uptown may have a point well taken too ...

truth is , rarely change out my rez at all either rather try & just let the ppms drop naturally with the topping off . And refresh with fresh nutes as he mentions , when needed . Depends on size of the grow & the rez of course & usually my concern is the rez is too cold .
(being on cold cement )

But do periodically run that UV sterilizer just to clear the decks in the rez & maybe mild flush only twice in flower . But have made entire runs without flushing at all with uptowns approach above & like him using RO water .

KISS is good & have a very big rez ...

i change nutes every two weeks but i don't do the h2o2 thing unless something starts looking or smelling funny. my system is home made and i don't have a chiller. with the rdwc i can run from october to may without any trouble. (live in colorado it's cold enough). do you add a cal mag to your water? have you ever had a cal problem and looked at the roots? i really don't know without pictures what the deal is but without seeing and smelling are we really sure this is pythium ?


so eazy do the roots stink? are they slimy or just off color?

 

[takeiteazy]

Cheers Guys. Trust me i have read and read on PYTHIUM. Had loads of awesome grows for years without changing nutes etc. Then BANG last 3 grows had it...After MEGA cleaning H202 etc..

Not using Hygrozyme but WAS thinking about it...

I have this on order - http://cgi.ebay.co.uk/Pond-UV-Light...Features_UK&hash=item483b5a4511#ht_3666wt_754

Not sure whether to put it inline with my chiller/pump which runs at full speed 1000L/P, just recirculating in the control res. Or

Use inline on my other 1000 L/H pump which feeds direct to my five bubble pots, not sure what the actually flow rate is but def not 1000L/H as it restricted due to dropping down to 4mm feeds to each bucket (could work this out easily enough though)

Also as stated i use Ionic Nutes and they also sell a UV filter, they also sell this to -

http://www.emeraldcitysupply.com/product.asp?CatalogCode=IONICUV

What do you reckon my regime should be peeps ?

Cheers

Help is much appreciated, are you mostly US growers ?

Don't add HYGrOZYME. Check the "strange slime buildup on roots" thread foe why.
