Glycerine changes the water surface tension thus making bone-dry soil take up water more easily and quickly. I believe something like "Wet Betty" is a branded product for such a purpose, but I am just looking at the generic stuff.
Has anyone tried that with old seeds for the "glass of water" germination method?
Just throwing it out there as I think It might "work" for the purpose of getting the water into the seed, but I have no idea if that affects the seed and in what other ways.
Anyone?
