yo peeps, im growing a dwc in distilled water from my dehumidifer. 70F water temp about 400ppm:wall:and using h2o2 the roots over last week started to go brown:fire:fucked off as started off pearly white plant about 4-5 weeks old. could it be copper or other shit in water . should i get purer water? could it be nutes too strong, could it be temps. i can't stick any picture wiv it nothing happens when i click the attachments tab?

I don't know much about dwc but I'd worry about air borne bacteria in the dehumidifier water.... IMO..

I'm sure others will reply.... Luck.....

Who knows. I'd drain and replinish the reservoir. Your pH should be between 5.5 -6.5 and your ppm sounds low. You know NOT to use H2O2 if you're using organics. Don't know about your choice of water. I havent ever heard of anyone using that method. It could easily be your problem. I was using r/o'd water but now I just use tap with some declor for Chloramine.

brown roots in dwc is root,

sorry to be the bearer of bad news, it often occurs once your res temps stay too high for too long

unfortunately its incurable, but you can control it and still get a harvest

Your water should be about 65 degrees and no more. If it is more you have a res heat problem. Move your res out of your growroom or buy a chiller.

Oh yeah, just some advice for next time. Build your room and run a crop with a soiless mix next time, until you get your temps dialed in correctly... then go hydro when its temp is controllable.

My room never gets above 72 and res is always about 64

why can't he do any other hydroponic method, why does he have to go use a soilless mix?

why can't he just get his temps sorted and continue with dwc

why does he have to go use soilless mix?

I have limped through with a couple extra air bubblers under the roots and heard of guys freezing PH adjusted water and adding a block once a day when temps get higher.

Because if you go soiless you have a better chance of surviving heat. And this is only for the initial set up if you can't wait for the temps to be stable and just have to grow something.

Too many newbies go hydro not understanding the basic needs of any growing thing and end up with brown roots and don't know why. At least if the enviroment is stable first, you have much less mystery when things go wrong.

Just many years of growing and knowing about stability of the room before plants go into it. Any experienced grower would agree!

how is soil any different he knows as much about that as he does about hydro,

its absolutely no different,

the main difference is that with hydro he can learn quicker, because he can measure everything, ph ppm and keep track of what does that and build a steady learning curve,

don't tell people how to fucking grow, help them to grow in the way they are doing

also i dont want to butt in a sweet fight or anything BUT....hydro is much more hands on and complicated than soil is, ive grown soil for over 5 yrs now and just went hydro about a year ago. first off, when you first grow marijuana in hydro (especially if youve never grown before indoor or at all) the plants become very finicky with nutes very quickly if you dont know what your doing or have a meter. i had a meter my first time and i even burned them a little, in dirt ive noticed u can bring ppms up much higher than in hydro and i paid for it for my first time. secondly, you can easily measure anything you want in soil also, just take some ph 5.5 water with or without nutes, dump it in your soil, take a cup and collect the water, measure the ppm and ph and thats a pretty good guess to what your plants are receiving. thirdly, when growing dirt you can avoid this very problem we're talking about, root rot, many first time hydroers either quit or lose whole crops to it, growing in dirt almost 90% eliminates that from happening as the dirt blocks much of the heat that plastic resevoirs soak up much of the time, so by growing in dirt he can avoid many problems as well as build a nice learning curve and get himself ready for bigger and better yields, once again didnt mean to get in your knit picking just wanted to throw my 2 cents as a long time soiler and a short time hydro grower bye.

but what do you learn from growing soil

you stick it in soil, you water it with plain water until the nutes run out then half ass guess at something like 2 tablespoons per gallon, and you never really get an idea of what works,


what do you learn from soil that prepares you for a hydro grow?

there are some things you cannot learn in a book or on the internet my friend, one of them is growing a full bloomed 10 weeks flowering marijuana plant, whether its soil or hydro, you cannot learn how to grow marijuana unless you do it for yourself, experience everything that can go wrong and that does go wrong. ive come to find whether your growing in soil, perlite,hydro or air, a marijuana plant is made by the person who took care of it, the light thats given to it, and the salts it uptakes, not so much the medium, mediums are more for increasing yield and getting faster finishing times, i know theres a many reputable on here (subcool) just for one that would choose dirt over soil any day simply because of the fine quality product you get out of doing it natures way. anyway what im getting at, growing weed usually comes down to 3 things, experience, experience, big lights :D anyways i got some cinderella callin my name fun chattin pz

oh and in case you didnt get the answer out of that, experience is what you get :joint:

but you have no idea really what you did, and you ask for reassurance every step of the way,

it all comes down to your learning style i guess, see i'm an activist and i learn by diving straight in, i've never had a failed grow even from my first one ever which was in hydro.

my point is not though that one method is right or wrong, my point is, lets not say oh you've fucked it, just go grow in soil,

lets help this guy get through root rot,

he now understands that root rot occurs when res temp gets too high, in future he could do something about it.

but for now we gotta help him do this hydro grow, if he gets to the end of it, imagine how much he will have learned as opposed to giving up on it and going and doing soil and getting a massive knock to his confidence
