Hey all, just a little trick I use to wet my seed-starting soil when the organics are so dry water runs straight through.
Mix your soil with water in a large bowl or in a pot with no holes in the bottom (you can even cover holes in the bottom with a piece of plastic wrap before putting in the dirt). Wooden spoons work great, but a stick will do the trick (or even your hands). Just do the water a bit at a time so it doesn't become soup or mud. When it's wet enough to start holding water, it's ready to go in your fabric (or whatever) and will hold water better without drama when you water the freshly sown seedling.
Make sure you clean everything before you use it so it doesn't get contaminated.
