Growitnow, being prepared is good ... but try not to overdo the pessimism there! I posted a question myself today about damping-off ... I discovered white fuzz on the surface of the flats just as the first seedlings are beginning to emerge. Like you, I expected the worst, even though I'd read that while there are lots of fungi out there, there are only 4-6 that cause damping off. I've increased soil temp, light and air circulation (removed clear dome covers), made sure there's no standing water in the base trays, misted lightly with chamomile tea, which some say has antimicrobial properties, and am keeping fingers crossed. It's good to know the hydrogen peroxide is an option if it's needed. Best of luck to you! Diane

There is a lot of info on the web about it, apparently... I'd never heard this either, but I might try it on my containers. It's 1/2C. 3% peroxide to 1 gallon of water. A lot of places give you the ratios for food grade (35%) peroxide, but that stuff is wicked; I'd rather not play with it if I don't have to... Alameda: What's your setup for germinating seeds with peroxide? I've never had success with germinating seeds in baggies, so be specific; I'm tired of killing things :) ~AOK

I was told to use a 0.1% mix when soaking seeds prior to germination, or when watering seedlings. This cleans the seed surface and discourages mold, fungus, and damping off. Drug stores sell 3% Hydrogen Peroxide, so dilute that 32:1. It is also great for plants already in the ground or in containers. I have used it stronger myself without any harm. If the roots are already rotted, I never brought back a plant. Please tell your stories for us. Stush
