I put my seeds in the soil at first sine of cracking takes them a little longer to come out but I figure the time I saved germing makes up for it. As for H202 I use a 30ml to 1 gallon mix to water my plants everytime, but I have not used it to germ seeds before. I might try the H202 out with germing some bag seed thats layin around, just to see if it works or not.
