I'm not sure why - but someone said a long time ago to soak your seed in peroxide vs water for germination, any one do this? What is the reason for doing so?

That advice is for seeds with a really tough shell like morning glories. Here's a great site with good info on using hydrogen peroxide

I've been using peroxide water for years at 1/4 cup to a gallon of water. I use it for all indoor seed starting and watering until they go outside. It speeds the germination of all types of seeds but has a much more important virtue. It practically eliminates damping off and any other pathogens lurking in the soil or on the exterior of the seeds. I would recommend it for any house plant or seedling because it takes oxygen to the roots, much like rain water. It makes over watering almost impossible. It also saves me from having to buy expensive seed starting media. I just use garden soil with compost mixed in. It doesn't kill insects though.

Yes, the regular stuff from the drug store. I see the link above calls for 1/2 cup to a gallon. I normally just eyeball it but use more like 1/4 cup. The point is that it's harmless to the plants. I always try to stay with bottom watering and nothing will rot even if soaking wet. Never any fungus knats either.
