This ingenious gadget is a great addition to your planting regimen: it makes free-standing plugs of soil for starting seeds. Plugs are the best way to propagate seeds in the most productive way because as the new plant begins to grow, the roots naturally stay inside the plug. This is called this “air-pruned”, (unlike what happens in a typical of seed-pot). The benefit is that the new seed starts aren’t root bound and are less stress during transplanting. Simple to use, directions are included. 8" x 2" x 8½" (four equal seed compartments). It really works. Made in England. See our website for additional seed planting accessories.
