Fuzzy roots?

Method: Ebb & flow system
Medium: Mini Rockwool/Hydroton
Solution: Chem
Problem(s):
1: Roots with fuzzy white stuff around them.
2:White moldy looking dots in the Hydroton and on top of the RockWool.
3: Black spot that looks like mold (could be algae but no other signs of it anywhere)
4: Basically killed them with to much H2o2(3%) (Directly poured almost a whole bottle into the Hydroton/RW cubes) The leaves are curling under and yellowing between the veins, but only on the fan leaves. The rest are curled as well but dont show signs of discoloration.
4.b: The root system took a HUGE hit from the h2o2 and they are turning brown and, what look to be, dying.


Solution: ? Green Cure has been ordered and its otw. What should be done with the weakened/dying leaves? How do you correct the root problem?

Any information on this would be helpful.

flush them if you can....but the H2o2 is the stuff you needed but its prob gonna be the stuff that stuffed them.... ironic

The key would to of not pored the whole bottle in. H2O2 is very strong and you might have done some huge dammage. I agree flush the hell outa them and let them flush for a day or two just to make shure.
I would say if your getting mold check your air temps and your watering is it to much??
I had the same problem, and it was that i was over watering. the hydroton rocks should dry out. at least on the top to prevent mold and mildew.
show some pic's man It might not even be mold ???
peace

1: Roots with fuzzy white stuff around them.

You weren't, by chance, mistaking the "white fuzzy mold" for root hairs were you? The fuzzier the roots, the better when it comes to root hairs. Fuzzy roots mean massive surface area for the plant to uptake water, nutrients, and air.

I'm afraid you put the nail in the coffin with the H2O2. Your concentration was way too high, and you ended up burning the shit out of your roots. H2O2 has a very limited use (eg. Sterilizing equipment, reservoir maintanance, etc.), and should never be used directly on roots in it's concentrated form. The most roots can safely handle is around 100ppm, which is around 10ml/L of 3% H2O2 diluted in water.

Do yourself a favor and throw out the 3% H2O2. If you insist on using H2O2, use 35% horticultural grade H2O2 and DILUTE. Unfortunately, there's a good chance the plant won't recover. At this point it's probably better to just start over.

Quick question: Was the plant in good health (foliage, top growth) before you added the H2O2?

I am unable to post any pics. I can discribe to the best of my abilities though.

The spots are circular and are/were... not crystaly as neut build up would be. They are white/off white and range in different sizes on the top side as well as fairly deep into the hydroton. The spots would wipe off but would not be dissolved in water. Also. The roots had white fuzzy stuff on them. I am unsure exactly what that is being as i have found little information about any kind of root fungus or anything of the such. I assume it could be the symbiotic type of fungus, but does that grow in a chem hydro set up? The air temp is on a constant around 75-80 with a fan constantly blowing a good deal across them, and watering times are 3 times in 24 hours. There was a time when there was 4 cycles for 15 min each. The 3 now are at 15 as well. The rockwool was/is seated down into the water though, i have read this is bad but then again i have read this is necessary? The lighting system is a series of T8's dropped down to right on top, pretty much. Heat is not an issue. The humidity is something i can not comment on. I have no tool to measure that currently but plan on getting a nice one soon enough.



I have gathered conflicting information going both ways on many different subjects. To cover the RW.. to not cover.. to bury.. to not bury.. to set in the flood.. to not set in the flood. Its all relative to your own system i believe but i dont have the first clue about hydro set ups.. This is the first go at it and the plants where doing awesome untill this mishap with the hydrogen peroxide. What would you have suggested the solution to be % wise. Also, I just ordered some GreenCure. What do you suggest with/for that?

Many times when the roots are in a very wet environment they can get very fuzzy looking. This does not mean mold each time, they can just go crazy in the wet and put out an over abundance of little roots. In the future you might take a small microscope and look. I did the first time I noticed a similiar condition and it was just new roots trying to start. As for the peroxcide, next mix half and half with plain water and mist the roots and then flush with water. Good Luck with the plants.

not my thread dude, But your right. personally im not all that worried if theirs a slight discoloration of the roots or about hairs. until i see stress in the plant.
and basicly the mold isnt going to grow whare its constanly wet, but somewhare that thare is a good air flow and damp conditions, but not wet.
Unless your letting your roots dry out completly, which the plants couldnt have been doing to well in the first place.
But any way, the dude should have posted a quick question before the H2O2 dump.
peace

I suspect that the "root mold" you were observing was actually root hairs and Yes, they do form in a chem hydro setup. Your biggest mistake is over analysing. Rule of thumb: If the plant looks good, don't fuck with it (if it ain't broke, don't fix it). Don't obsess over travialities, if the plant is growing well and is healthy that's all that counts. I hope you've got some more seeds because your best bet is to start over. Recovery is unlikely, and even if it does recover it'll likely take weeks or more, which is precious time that could be spent growing a new healthy plant.

You guys have been helpful. Thank you for your quick replies and knowledge of the issues. I will make notes for future references. The girls dont look like they are going to put up all fours but they will need a crap load of TLC for a good bit. The res has been changed, the PH was between 4 or 5 =\. It had been a steady 6-6.5 for the past month and a half. I got word that within 5 min of the h2o2 pour that the water cycle started so that probably helped more than hurt but still wasnt good as it had 2 cycles with an average of 4.7ish ph... I hope things get better. I will post on progress after a bit.
