On the Starting Seeds page, I showed how to use a soil block mold for starting seeds. After much experimenting, I have made a few modifications to the process.
- I no longer try to pack the soil mixture in tighter than I can get by just pressing down several times. I had even tried using blocks of wood to pack it in tighter. While that gave good results, it was pretty tough on the hands, so I went back to the method recommended by the manufacturer. I still try to pack it in as tightly as possible, but only by pressing the mold into the mixture.
- I no longer use a bucket to press the mold into the mixture – I now use a stainless steel warming tray that I bought from a used restaurant supply store. This is much easier to work with and it allows me to make much better use of the wet soil mixture than I could with the rounded sides of a bucket.
- I have added galvanized hardware cloth in the bottom of the seed trays. Previously, the blocks would get damaged when I had to move the trays. The stiff, flat bottom that the hardware cloth provides keeps the blocks from bumping into each other.
