Stem Rot?

I am seeing some type of mold at the base of the stem on my plant. It also seems like its rotting out at the base where the mold stuff is. The plant is growing fine and doesn't seem to be effected by this though. What can I do to fix this?

Here's some stuff I found, see if it matches your symptoms

[FONT=Verdana, Arial, Helvetica, sans-serif]Moulds can completely destroy a garden in a short time. If the climate in the grow room is well-controlled, moulds, in general, have little chance. Moulds and fungi thrive very well under hummid conditions, preferably without much air circulation. Under these circumstances, mould spores, which are always present in the air, search for a spot to grow into mould cultures. If you don't succeed in preventing mould growth, then you must do something about it as quickly as possible. With light mould growth, immediately remove the affected plant parts, and then create a climate in which cannabis does well, and moulds don't (good ventilation, control of humidity and temperature, and putting your plants on a medium which is not too wet).[/FONT] [FONT=Verdana, Arial, Helvetica, sans-serif]If there's already too much mould present, you don't have much choice but to spray with poison (fungicide). Repeat the treatment after a few days, even if you think the first application has definitely helped. Still, improve climate control and groth conditions. Fungicide treatment should always be a last resort. It's not healthy for young plants or people, so here, it's also: 'prevention is better than cure' [/FONT]
[FONT=Verdana, Arial, Helvetica, sans-serif]An often-occuring mould affecting cannabis is pythium. This mould causes root-rot, and rot in the lowest part of the stem. It appears most in young plants, and in cuttings. Larger, healthy plants are less sensitive to pythium. Plants get 'falling-over disease' with a serious pythium attack. We don't have to explain what that means Pythium is recognizable by the bark at the base of the stem turning brown. In the beginning, the 'brown attack' is easily removable. Later, the rotting process eats deeper into the base of the plant. Pythium is a fungus which flourishes best in wet and humid environments. Pythium spores spread only through water. Two kinds of spores are formed; Swarming ones and stable ones. The swarming spores germinate best at a temperature of approximately 15 degrees Celsius, while the stable spores germinate if it's relatively warm; around 28 degrees C. To prevent a pythium attack, a constant temperature of the soil or rockwool is needed. Large fluctuations in temperature should be avoided. Pythium can only be fought in a limited manner with chemicals. A proper relative humidity must also be maintained (not too high). Leaf moulds, such as mildew, and thread moulds occur less frequently than pythium.[/FONT]

Well, if the plant is big enough to have branches, and is still living, then you probably don't have a deadly fungus. But if you do, and the branches are healthy enough to root, then they will make fine plants.

I had a plant do that, a few days later it fell over, a few days later it was dead.

You need to keep your stuff more dry.

i no why the roots are doing this, and i now how to stop it!!!!!1 listen up because i spent the whole day at collage reseaching this, and i now my stuff

i had the same problem, i have 5 aerogardens, all filled with plants frowing, now the first time i did this, all my plants had stem ort.

listen if you have the aerogarden- what you need to do is, TURN THE WATER PUMPS OFF. THERE ISNT A BUTTON TO DO THIS, BUT WOT I DID IS PUT CARDBOARD OVER THE FUSE, AND THE PUMPS DNT PUMP WATER ANY MORE.

SECOND THING, U NEED TO GET A FAN, AND FAN U PLANTS !!!!!

3RD THING, NOW UR PLANTS ROOTS R LONG ENOUGH U DNT NEED THE PUMP, U ALSO DNT NEED AS MUCH WATER EITHER, SO U CAN EMPTY SUM OF THE WATER


do these 3 things, before the stem rot and u will b fine. u mite even be able to save ur plants if u do this wen they r already rotting


take this advise people, it saved mine

Keep the water on the roots not the stem. As a quick fix, when you first start seeing the brown "rust" color at the base of the stem, dry it off, scrape the brown stuff off, doing your best not to damage the stem, then take two fingers dipped in baking soda and gently rub it on the stem - the baking soda will help absorb the moisture and hopefully prevent the spread of the fungus.

Hope this helps.

okay sometihng weird happened. This is about two days later.......so one has died another is on the way but one seems to be fighting it. It was leaning over but it started straightening itself back up Im afraid to do the baking soda thing on it for fear of killing it the stems are tiny, theyre only about a week old. Any chance of it warding the fungus off on its own? Its growing new leaves and straightening up as I said before...crossing my fingers

as others have said, its the wetness at the stem causing this issue, and i have seen it happen when clones are left in a cloner too long.. (3+ weeks, etc).. what you need to do is the following...

1. lower the water level inside the aero/hydro system a little. if you have air stones bubbling inside, that causes water to reach the top...
2. use a timer on your air pump to go on/off/on every 30 minutes.. and then once established you can push to 15 on, 45 off. thats what i do, but i am using a cloner that uses a water sump instead of the air bubbler inside but its the same principal. you want to get them wet, but not soaking in water 24/7 or else they will rot...
