dwc roots going brown, why?
- Thread starter jammin26
- Start date
I'm in the process of harvesting two plants that I grew in a DWC 5 gal bucket. The water has been basically room temp the entire grow and I haven't had any root rot or other heat related problems.
Room was any where from 72 to 85 over 3 months.

I've been told root rot can be caused by lack of oxygen. Would upgrading or adding a another water pump help with this problem?
nah.. my pump is 7.2L/min only using 10L pot. could my tap water have shit in it? its 250ppm and on 0.4(ec) pen. high ph ,like 7-8. but comes through copper pipes. the dehumidifier aint nothing to do with a furnace its just just a unit in the room which pulls moisture out of the air and collects it. it has ec of 00 sop must be below 64ppm and ph 7. i think im going to use this and boil to remove bacteria it should be ok. im using h2o2 aswell snd it didnt seem to do jack

dude, my tap water is 350+ ppm and i grow these -
collecting the water from you dehumidifier and boiling it is WAY too much work. those few ppm in the dehumidifier could be toxic due to the collection method of the unit.
use your tap water. let it sit out overnight to evaporate the choline then use it. if the ph is high then adjust it.
you say you used h2o2 and it "didnt do jack"...what did you expect it to do? how did you use it?
i added the h2o2 (17.5% oxyplus) at 0.5ml a litre of res water. first time i added it the roots were slightly discolored (going brown) couple days later they were worse. but the roots were fine to start with then i added 300ppm nutes and got brown spots on the leafs and roots started darkening.
can it be too do with the temp of the plant compared to the roots - i.e the green part should be at least 5 degrees warmer than the roots?

im pretty new to DWC, been growing for close to a decade though. my roots used to get a tan - brownish tinge. now i add 5ml of 3% every day or two to my 2 1/2 gallon bucket and they stay pearly white.

using h202 once will not cure it overnight, root rot is almost impossible to get rid of man, u just have to cope with it now, look at skillwills post, fuck the water ur waters fine, balance the ph right and keep the ppms down after u add nutes, figure ur ppm iS ALREAD Y 250, ur gonna have to add some ph dowen or sodium bisulfate which is at least another 100ppm to get it from 7 to 5, so u already got 350ppm , dont add 1500 ppm then ask why ur shits burning cus thatll be 1800 ppm, go from 350, add 650 for 1000 during flowering, if thye like it give em more, be careful of ur salts though u can really fuck em up

You're not reading dude, I can't teach you. FIRST OF ALL your not just watering with plain water and no its not SOIL, I said, SOIL LESS... Big difference.
Pay attention cuz I am not typing it again.... ready...
You are using soiless for the FIRST show in a NEW room because your a retard and you don't know what your humidity, temps or air circulation is like yet, again because your a retard. You still have pens and you still check ph AND YOU STILL DO EVERYTHING YOU WOULD NORMALLY DO, EXCEPT (pay attention here!!
) YOU DON'T HAVE A WASTED CROP BECAUSE YOU NEVER KNEW WHAT WAS WRONG IN THE FIRST PLACE BECAUSE THEY LISTENED TO A JACKASS LIKE YOU!kiss-assSTOP GIVING ADVICE.
Funny thing, every time you post a reply, you make yourself seem less credible because of the naive arguments you make. Keep growing your dirt weed f-face!

Looks like things are going as I expected, but you probably already knew that. Next time don't be ungreatful for the advice thats given to you for FREE. kiss-assyo peeps, im growing a dwc in distilled water from my dehumidifer. 70F water temp about 400ppmfucked 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?
Next time don't send me a private hack you spineless jerk, do it in a forum so others can avoid you too!

At the off chance that this is serious. STOP using dehumidified water, thats for the air in the room your growing in, not to water with... SERIOUSLY????? YES use tap water, yes adjust the PH and yes add nutes to it and yes add peroxide to res for oxygen (heps reduce bacteria forming). I usually fill a secondary res the day before with tap water that sits for 24hrs or so, that way there is less chlorine and other additives.jammin26 said:

I never said give up hydro. But your slow, so I'll try 4 times now.
I said that, people should not get sucked into spending a bunch of money and time building a hydro set up until they have grown something and understand the basic principles. Otherwise they have shit happen to them that they cannot diagnose and instead resort to retards like you who mislead them into growing your fine American dirt weed.
I absolutely love hydro, if you know what you're doing..
I'm not the enemy ass face!
sorry cashcow1000, do not waste your time with me. i am a brainless waste of time who has spent 1o years trying to grow and still can't.
one last question for anybody-
i have a dwc, everything simple as, got 1 plant , 6 litre res, using tap water and h2o2 , using 0.2 ec nutes everything should be fine only starting to get browning roots.
do i need to use more nutes as using very little or is it the nutes that is turning the roots brown? cos i think i may have picked up a dodgy bottle of nutes.

umm.. water that comes from the dehumidifier is about as pure as it gets.. it is cleaner and better water than what comes out of the tap,. the only problem might be if it runs through copper tubing, which is not a bad deal as long as the water coming out is not overly acidic.
but anyways, dont be a fucking asshole to people asking legit questions, its not like he is spreading disinfo, he is trying to get advice, so either be constructive or go try to remove the dick from your ass.
ok, so, back on topic... Original Poster, you said you were using a 7.2L/min pump? are you not using an AIR pump in your DWC? with any dwc, where the roots are continuously suspended in a nutrient soulution, the key is to have 65-70 degree water, and a very hefty air pump, and a large air stone keeping the oxygen levels high..
do the roots smell kinda nasty? because if not you could be ok, and your nutes could be staining the roots brown. if you can get a hold of 35 percent h202, put 1/6 h202 and 5/6 water, then dunk your roots in it for about 30 seconds... this will fry all the root rot, and then you can put it back in the dwc system..
dont mind the haters, ask questions if you cant find answers
cheers flojo, i thought my head was in the right place. yer, im using an air pump rated (HAILEA ACO 9602) 7.2 Litres per minute and i've only got 7 litres of water in my resorvoir. i tempted to start using my dehumidifier water after reading that. room temp is 17C so water temp is just below that, shouldn't be probs with heat, this aint texas. im thinking its the nutes but how do u keep white roots while still using nutes? i may have to buy new nutes and remember to pick up a sealed bottle or use some gaurdian angel or root guard, im already using h202, or otherwise known as oxyplus which hasn't really impressed my so far. on the bright side ive got a seedling grown about 2in since yesterday in coco.
