How to fight damping off

My environment is very bad for clones. I use flowering tent to root them, because I dont have other space. All clones stay in shadow on the floor under very big plants there is no bright light down there. Light cycle is 12 /12. Some of them put roots but others dead without roots. I have also big and healthy clones very well rooted also dying down there. Finally all my clones is just dead. I want to reveg all plants after finish flowering and will try to make clones again. I really want to avoid this happening again help me to fight this disaster. Im in coco any help with tips fot reveg will be also welcome, because I never reveg before.

Personally, Botanicare Hydroguard solved all my damping off problems, and any other inoculant/tea/microbial product with sufficient amounts of Bacillus subtilis will likely work just as well. Good luck! :tiphat:

oxygen. roots need oxygen, if there isn't enough it stagnates and rots. if you're cloning in water change it out every few days, if you're cloning in coco or whatever. let it dry out some before you moisten it again.

Your light cycle is 12/12, not ideal for clones. 18/6 much better. Damping off occurs when media is too wet and not enough air circulation on the crown of the plant. A small fan blowing gently on the base of the clones helps. Make sure to not over saturate the soil, rockwool, or whatever you use. Best of luck to you!

Is this damping off or different type of fungi? Its happening also on very big clones in pots full with roots. Strange but roots is white and looking good. Is damping off atack roots or directly attack stems and leaves. Or maybe enter inside the plant?

They look over watered. They need more light and let them dry out. A transplant would be the best thing for them. Get them out of that soggy soil.

Not damping off. Those plants have already rooted? If so get them some more light.
Yes this happening on very well rooted clones. With unrooted clones also and with clones just putting roots. With some just tops dying. On other firstly leaves is affected. Some with broken stems. Fungi jungle.

I dont think I can save this plants. There is too dark and moist under canopy level. After harvest I will try to reveg plants and will try to make clones again. Also will try to make small mother clones room. Maybe need to spray with something after reveg to kill all this fungi? Can I make flush before harvest or I need to feed to the end to have successfull reveg? Im in coco.

Ive seen that before but tbh I don't know what the cause is. If this is happening to well rooted cuts and the roots look good, I would consider looking at environment. How's your humidity? Airflow, cleanliness, etc. spores of some sort can thrive if enviro not dialed. I'd pick the rotting foliage off, water and foliar with a well brewed compost tea to help fight pathogens and boost immune system. Dial in your enviro make sure its clean. These are all just guesses tho, wish I could be more help.

You can flush. Don't let her yellow too much she will feed off the leaves in reveg.

Tips for successful reveg: leave as many leaves on there as possible. Cut buds off and leave fans on wherever possible. Leave the fluff/larf on. Sacrifice a little bud to save the plant, the more foliage you can save the better your chances. Let the medium dry out a little before harvest, and don't water during the reveg unless they really need it. If you want give a small dose of nitrogen after you chop.They will be drinking a lot less, often I don't have to water at all for the reveg, but dependent on the plant and amt of foliage left, and the light they are under.

Humidity is very high and hps can't penetrate because floweing plants is very bushy. I brew essence last night and spray flowering plants to avoid bud rot and also spray clones but its too late I loose around 50 clones some rooted some unrooted.

Plants is big and I will have a lot popcorn and foliage to try reveg. I will follow your advice Scrappy. Thanks for help me. Im in coco hempy actually it is possible root mass to dying if I not watering them too long? How much time is needed for plants to start putting new vegetative growth? I have 200 w cfl and 600 w mh. Which bulb is better? What about light cycle 18/6 or 24/0?

The halide is a better bulb. Sounds like the humidity/lack of light is your problem. Add ing a fan or 2 to increase airflow will help with spores and whatnot. There's a grower on here, forget the name and thread, but he is very successful with high humidity growing. He said his success is due to a large extraction fan for fast air exchange and a ton of airflow in his chamber. Said he rarely if ever gets rot. If a dehumidifier or air conditioner is not an option that may be a path to consider. If I find the thread I'll link it.
