You dont say what kind of seeds.....................I dont think this is some kind of magic instant germination formula. It may help some types of seed that are slow, it may not make any difference at all.

Why dont you try some of the same seed without the peroxide soak, and let us know if you find a difference.

I think you may be mixing together a couple of unrelated suggestions. First, many large hard seeds will benefit from pre-soaking and it is a fairly common practice. However it is done with just lightly warm water and for a period of 12-24 hours.

A brief soak in a peroxide mixture (10:1 of water to peroxide) is recommended by some seed savers as a way of disinfecting saved seeds before drying them for storage. Some also use a diluted peroxide mist for stopping fungus/mold growth on soil. But adding it to a pre-soak isn't a common practice and while it might disinfect them it really serves no other real purpose.

Since you only soaked the seeds for such a short time I doubt the peroxide hurt them even though it is a stronger mixture. But how fast those seeds will germinate will all depend on the soil temperature used.

Most melon seeds will germinate in 4-8 days if given soil temps between 70-75 degrees, 3-5 days if provided with warmer soil. In cooler soil it can 10-14 days.

Let us know how yours do.

Please, could I ask where you got the 3 to 1 mixture and the 5 hour number?
