A more advanced way of germinating onions is in a plastic bottle. A half-liter plastic bottle is cut off, the neck is inserted into the bottom. A bulb in such a container will stand like a soldier on guard
You can sprout a lot of onions in greens in one plastic bottle: cut the bottom, cut along the perimeter of the hole, fill up a layer of earth, lay out the onions, again a layer of earth, onions, etc. We strengthen the bottleneck in a flower pot.
