In this tutorial, we will share how to make small paper cups for the growing seedlings. Although they seem fragile, the cups are easy to make and have many advantages, as discussed below. Take a plastic pipe (PVC) with a minimum diameter of 7 cm and a length between 15 and 18 cm. Make a mark at 10 cm. Prepare newspaper strips, or other biodegradable paper (do not use plastic coated paper) for the cups. Wrap the PVC pipes with the strips, giving 3 turns, and considering the mark of 10 cm. The important thing is that about 3 cm paper should be left under the plastic pipe. Look what to do next here.
