Making soil blocks, this is another way to start seeds. You need to get the right mixture of water and soil to make a sticky mixture. Than you use the soil block maker, it’s like a mold, than you put them in them in these trays to plant the seeds. It’s a great system that makes for little by-product from year to year. Unlike those plastic trays you usually buy at commercial greenhouses. Note the stack of firewood in the background.
