Garden Seed Planter Can I Use Compost All By Itself?

Can i use compost all by itself? - garden seed planter

We plan our vegetable garden, and I wanted to know whether it is possible to use only in boxes of compost single window. This is the first year, we use the compost in the garden. My seeds are already there. You still need a few weeks for the transplant. But I filled a pot with compost alone, but then I started thinking that I could go wrong.
