Okay, so I changed it to soaking the seeds since the top of my refrigerator is cold. But I read that 8 hours should give them a good start and I would be able to see which seeds were good and which ones were bad.

Hey there!

I don't know about the Impatiens seeds.. but I use coffee grounds in my lasagna beds. Do a search on lasagna beds and you'll get a ton of info on using grounds in the garden. I've never tried them before with seed starting tho.. let us know how it turns out. :)

Update
So far the Zucchini with the coffee grounds is above the surface today (leaves haven't opened yet though). The other one is not up yet. As for the impatiens, well they take so long to grow anyways it will be a while. So far, it's coffee ground soil-1, regular soil-0.
Hm, I might do this with all my seeds if there are no adverse affects other than this. I wonder if I can have my vermiculite soak up coffee water? Or would it just make my seeds moldy? I'll have to try it with my basil. So far, basil is the fastest growing seed I have (5 days). Anybody have a suggestion other than coffee? I'm open to try it as long as it's cheap and I don't run out of seeds.... :P

okay, score change, I looked more closely at my labels: Coffee-0, and regular garden soil-1

Well, now I know not to start seeds in coffee grounds. My zucchini that I put in coffee grounds still hasn't come up, but that's fine because I only need one plant.
