Whats your nute solution at? When I did a DWC I started it at 1/2 the level for the seedlings and stuff and in the first 2 days had roots from a clone. After that it didn't really stop. Weird that they only have 4 roots, mine erupted as soon as they hit the water. Are the roots just straight or do they branch out all over the place. Man I'm rambling, I'm so high, fuckin trainwreck......

Sorry not to make it more clear and stupid me should take a pic or 2 also but there are like 4 roots that are about 7" long that reach the water and there are others coming out of the hydrotron. The plant has more than 4 roots total, sorry for being misleading. Root growth looks good it is the top side that just doesnt really seem to being doing much. Thats why was wondering if it had to do with only 2 100w cfl's atm compared to my 400w MH in the tent. Nute strength is full. 5 ml per gal of micro/grow/bloom PH at 5.9

they will come, due time.if 4 have made it u got 40 more on the way in a week or 2

kk thnx for the support I'm going to add 2 horizontally mounted flouros on either side and keep the 2 100w cfl's over top. All will be running 6500k daylight bulbs
sorry for all the stupid questions, I just got so used to my 2 E&F units I dont even think when I work with those and this is the first DWC I have done and didnt really know what to expect.

did rez change yesterday along with the 2 cabs (the normal Sunday duty), and all looked real good, roots coming along good and nice and white. Tonite I go and check on my lil bucket baby and root part that was dangling in water has a brown tint to it and almost slimy looking (didnt want to touch as roots still look on fragile side). So now I sit here and think wtf?? If a small amount of light was getting into the buckey could this be a cause?? PH is running right around 5.8/6.0 and res temp is 68/73. I know temps can cause root rot but I dont believe I am even close to being high. Have 2 6" airstones that are bubbling there arse off so lack of O2 should not be a cause. What am I leaving out??

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 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...

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

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

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

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?

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

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

/bump

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.

i woud raise your water level,browning of the roots is one of 2 things rot or nutrient stains. deff bring the water level back up to the bottom of the pots,u wont hurt anything.hell thats how i veg cuttings,just a tub of water with vitamine b1 and superthrive.they sit there for about 2 weeks.as long as u have oxygen u wont have a problem.cannazyme will help like some one else sed,it eats old bad roots and causes benneficial bacteria to be released.how far away are your lights.my guess is your lights are 2 far away to really stimulate growth and 2 having the added stress of just trying to stay hydrated.so give it a shot for about a week .put those flouros about an inch or 2 from the top and raise the water level i bet u will see major growth in that time,deff 2/3 inches and much more root mass.if u want to stabalize your rez temps u can buy a seedling heat mat and put it under your bucket,or go to petsmart and buy aquarium heater with a temp controll for like 10 bucks.

Are you saying the roots of your veg. plants actually sit in water with an oxygenator?

That makes me feel better at least... i kind of figured it was from the big bloom since it looks like chocolate milk and now the roots are brown.

the browning of my roots has decieded not to be a problem as a lil H2O2 once or twice a week and we good. res temps run from about 68-72. lights and distance are 2 100w cfl about 20" overhead and 2 24" flouro tubes as side lighting about 12" from plant. water level is about 2" below basket. lights run 18/6. nutes are at 100%, same mix as I use in my E&F. did I forget anything? once again could this slow growth be because I am comparing this setup to my E&F stup running a 400w MH bulb?
