The method is very easy and inexpensive. It does take patience since most start their seeds outdoors in December and January. I was late starting this year, and since we had a very late Spring, I was VERY lucky we had nice chilly weather!
I have many sprouts already! Most of these were buried under 12 inches of snow not too long ago!
I will show progress pictures in the next week or so. My sunflowers are already 2 inches tall!
