Original Bio Dome with 18 Whopper Cells, Seed Starter Kit, 18 Growing pods

Climate management. You can detach the transparent vent as the plants develop, but initially, particularly when starting seeds in late winter, it provides a significant boost of warmth and moisture! Exceptional rooting substrate. In each cell of the polystyrene planting tray is a bio sponge. Bottom irrigation. Water the base of this tray, not the bio sponges directly. Add sufficient lukewarm water into the base until the polystyrene tray floats. Include a small amount of the special seedling food (included) when the sprouts appear. The bio sponges will absorb precisely the water they require. As your plants grow, their roots will extend downward and outward, rather than spiraling or fanning out near the surface as commonly observed with top-watered seedlings. It is not possible to over-water this system. Root vigor. This relates to the watering method -- these seedlings develop a comprehensive root system that grows straight down and out. When it's time to transplant, you can observe roots protruding from all sides and the bottom of the bio sponge! Transplant simplicity. No need for the multi-step procedure of moving a plug into a pot and then transplanting from the pot into the soil! When you start your seeds in this system, they can be transplanted directly into their final location. The bio sponge remains intact, while the roots easily spread beyond it into the garden or container soil
