If you really dislike the task of watering your plants, you can make a super easy DIY self-watering planter! All you need is an empty coffee container like Folgers, an empty 2 liter soda bottle, a knife, a Sharpie, and some scissors.
YouTube user mediamaker2000 shares his few step process to a self-watering planter that is convenient and easy to make. Because it is a sealed system, it lowers water consumption by greatly reducing evaporation, and it keeps insects out of the water supply. All you have to do is follow the steps in the video, put your dirt in the 2-liter, plant your plant in the dirt, and put the water in. And because of the see-through 2 liter, you can easily check to see if your plant is rootbound. This kind of planter, although not large, would be great for growing herbs, or mid-stage growth of things like peppers, tomatoes, or even radishes, onions, or lettuce.
