A plastic container can work as a mini greenhouse for your plants, protecting them from pests and providing a humid environment. Start by getting a container from a grocery outlet
To create a self-watering planter, one container with drainage holes will sit atop a second without holes. You will need scissors, an awl, or a drill to create the holes.
Wash the container using hot water and dish soap. Remove the transparent plastic lid and cut, drill, or punch drainage holes in the base — at minimum, seven eraser-sized openings.
Cut a hole in the lid if you want to release some condensation and make watering easier. Plant your seeds or cuttings into the cells, water your soil mix, and put the lid on.
Place your tray in a warm spot until the seeds sprout or cuttings take root, then move it into full sun until the seedlings are ready to be transplanted elsewhere.
