stupid DWC ??

[DreadedHermie]

What's your water like?

If I use water from my well I get stinky brownness (smells like a wet dog) in less than 24 hours. But my rez temps are in the 80's.

Switched to distilled + calmag, problem solved.

I've even used chlorine bleach in the rez (1-2 ppm) despite some "experts" telling me that'd kill my plant. (Scorched her a bit, I'll confess, but I killed the brown slime and the plant survived). A more conventional approach is administration of 3% H202 at 5-15 ml per gallon, at 3-day intervals.

But if you are inoculating a warm nutrient solution with bacteria/fungus (with no natural controls like beneficial organisms) from your water, rapid slime growth is very possible.

I dont run DWC as of yet but thinking about doing a mother plant this way and continuing E&F in my cab and tent. so if I have a 5 gal bucket, netpot lid, airstone and pump what would the simple method be?? just didnt think popping the lid of and exposing roots to light to change water was a good idea but I have no clue hehe :wtf: Rating: 5

I using tap water, same as I have been using in my E&F systems for over a year now. I get my yearly water report but dont have a clue wtf it says since there isnt a ppm are anything of the sort in it. added 2 capfuls of H2O2 last night to the 3 gal of water in res and this morning the roots look ALOT better. Doesnt appear to be slimey and brown color is disapating. When I changed water on Sunday I wiped out the bucket and rinsed best I could and whaite rag I used for wiping did remove a brown film from sides of bucket and tops of stones. I starting to think maybe H2O2 is gonna be a constant add to the mix. Also added 2 24" flouro's to the lighting setup.

Well, tap water, sure...

But where was it before it came outta your tap?

A well/aeration system (no disinfection unless you're doing it, and possible fungal / bacterial load) or a municipal water supply (treated with chlorine / chloramine / whatever) and probably "clean."

I'm gonna guess it's "city" water...since somebody gave you a report..and since it's worked okay before in E & F... :thumbsup:

Mine's infectious right outta the tap. I won't drink it...

Sounds like you're getting it under control, though..good luck...:hippy:

Could the slime be caused by res/nutes being too cool? I was vegging under cfl's and had low temps and a slight brown tinge to roots. I added cannazyme just in case. Not a problem now i'm flowering with a 600w HPS.

Re: changing nutes, I always swapped buckets but now the root mass is huge and i'm doing a scrog so decided to buy an extra water pump. Same as what avon211 suggested.

sorry DH it is City water.

right outa the tap .... boy I can be such a dumbass sometimes lol :jointsmile:

[DreadedHermie]

boy I can be such a dumbass sometimes lol

You? Think I couldda asked the question better? (What's your water like)...Well, it's..er...wet...and...hardens up in the freezer...unhhh....

I was just trying to figure out if funky well water could be causing your problem, because you can just boil that to fix it.

Now...what's your "capful" like?

[tinytoon]

exactly as stated on this 1 lol. the cap of the H2O2 bottle is the cap I mentioned so I will guesstomat about a teaspoon is a capfull :thumbsup:

ok I feel really lost in the world of DWC. pics below. Bucket has been running for 4 weeks now and I really expected more by now unless I am just fucking it all up without even knowing which very well could be the case. I guess my big question at the moment would be when was i suppose to drop the water level? I mean when i started I had the water level just below basket and bubles would pop and spry Hydrotron like it was suppose to then when I had about 3 or 4 roots that were in the water I dropped the level about an inch or so ending with water aprox 2" below basket. I know I am only running under 2 100w cfl's and a pair of 24" floruo's but talk about snail slow. open to all input be it good or bad :wtf:

im still a little confused about this as well Tiny...

Your brown roots sound like mine... I thought it was from the bat guano FF stuff... Big Bloom. My roots are totally brown and eww looking. Have been for awhile but absolutely no negative effects on my plant. In fact its the best looking plant ive ever had. I also use tap water.

I have my water lvl super low compared to the bottom of the basket... Maybe 8-10" and mine does fine. Id love to hear the proper lvl from some more experienced people.
