I dont grow hydro but I have to agree with colarado, I mean, If you drown the roots wont they turn to mush? roots need 02 and under water they cant possably get all the 02 they need with just a bubbler.
Think my plant is DEAD :(

Wrong =/ my roots are submerged 24/7.

18gal. dwc 4x plant. StealthHydro.com the Oxyponic set. 1000gph Air pump.

well like I said, I dont grow hydro sooo you may be right. but it made sence to me. so you must have one hell of a pump?

No amount of GPH or bubbles are going to oxygenate a submerged RW cube..... a completely saturated root zone is a root zone deprived of oxygen. Yes the lower roots are in the water 24/7 but you don't run your water level all the way to the top. Once again, the point of DWC is to feed the roots with a mist.
What did you get your plant in mikmike? Is it in a RW cube or something like that?

The POINT OF DWC is not the MIST anything its for your roots to be DEEP in the WATER... i think you have your hydros confused. I can have the water at the base of my stem, maybe your using walmart fish pumps

No ammount of GPH. sorry but if you have enough bubbles (gph) you'll be fine Filling to the TOP.. Im sure his plant is suffering from being in a Coffee can much more than being FLOODED..in DWC

I think his coffee can was working well untill he went to flower, as he said it was doing fine for the first couple days then went to shit after the switch. i think he over nuted them.

Or maybe I'm not trying to fire up a generator to run my air stones.
And no dude, YOU are mixed up on what DWC is REALLY about.
And I quote:
Traditional methods favor the use of plastic buckets with the plant contained in a net pot suspended from the center of the lid and the roots suspended in the nutrient solution. An air pump powered aquarium airstone oxygenates the nutrient solution; if sufficiently oxygenated, the plant roots can remain submerged indefinitely. Once the plants are ready to flower, the level of the nutrient solution is gradually reduced to expose the roots to the air. Plants absorb vastly more oxygen directly from the air than from the oxygen dissolved in water. Deep water culture allows plant roots to absorb large quantities of oxygen while also allowing the uptake of nutrients. This leads to rapid growth throughout the life of the plant.A few key take home notes there are upon flowering the water level is reduced to expose roots to the air and more oxygen is absorbed from the air than from oxygen dissolved in the water.
The misting I'm referring to is what keeps those roots moist and doesn't allow them to dry out and turn into stem like material. An every day example of this is when tree roots become exposed. They develop a bark look to them and are "hardened" compared to the roots deep in the ground that are getting water. It sounds like you bypass that by running abnormally high water levels with an overkill pump.
I feel like you're using your exception as the rule rather than giving advice based off what most DWC users do. It refers to what you're doing when it says if oxygenated enough roots can remain submerged indefinitely but then goes on to state that method isn't the best way. Plus I'm betting your pump is loud as hell!

In a DWC.. 90% of all roots are underwater 24/7

He over watered. We'll all see in a few days when he's still feeding his plant yet it looks better cause it's not being over watered.

His problem is the Size of the Container more than anything to do with DWC man.

I agree that his container is gonna be too small. When my plants are done they'll fill several coffee canisters with just roots. Much less the nutrient solution. Might be time to upgrade that mikmike

durring flower he would be refilling daily maybe even twice

ColoradoLove, you are all mixed up with misinformation bro. Research DWC a little more before you spread more bad info. The "key" or "main part" to a DWC is the roots grow INTO a highly oxygenated nutrient mixture. It has nothing to do with "misting" of the roots by the little oxygen bubbles popping at the surface. That's some of the goofiest shit I have heard in a long time. No doubt the humidity created by these little pops helps the root system at the base of the plant, it has nothing to do with a successful DWC. If you want "misting" you want aeroponics which is sometimes used in junction with a DWC system. The main key to a successful DWC grow is the aeration of the water. The more bubbles the better.
MikMike, it looks like you have been frying that plant. Also what is the water temp? You want it at 65 deg F all the time. Anything over 70 and the plants ability to take in oxygen is diminished as well as increasing the risk for root rot, which maybe be why your roots are all brown. Good Luck.

Here is a recent DWC Q and A for all the newbs.

Thought I would stop back in and see where this thread goes.
First of all, much much cleaner grow room. Your plants will appreciate it.
Second, is your main light source a Quantam T5 unit? If it is, it needs to be almost touching your girl in order to get enough light down to her. That really isn't enough light to effectively flower her under. You could possibly fabricate some reflective walls using cardboard and polyfilm or mylar to reflect as much of the light that's being wasted back at your lady. I really think that if you can add some more light to your girls, they'll pull through. If nothing else, if you haven't already, pick up some of the red spectrum t5's for it and like i said, get it much closer to your girl. You could be with probably 4 inches of your top. Just hold your hand under it first to make sure that you don't burn your girl.
Hope your girl pulls through and happy growing to you.
