This video shows how soil blocking is an effective way to start seeds indoors without using plastic trays, by compressing a nutrient-rich soil mix into small cubes that act as natural containers. It explains the process of making the blocks, choosing the right soil mix, planting seeds, and bottom watering to encourage strong root growth. The main benefits include better germination, reduced transplant shock, stronger roots, and the ability to grow many seedlings in a small space. While it takes a bit more effort upfront, the overall result is healthier plants and a more efficient, low-waste system for starting seeds.
