A basic self-watering system can be constructed using little more than a water bottle. All you need to do is cut the bottom off the bottle and poke a hole in the bottle cap using a skewer. Then, simply add the inverted bottle to a normal pot or planter.
1. Prepare your wicking bottle. 2. Cut a hole in the center of your saucer, just large enough for the bottle to fit through. 3. Cut the bottle so it will sit flush with the saucer. 4. Prepare your watering tube. 5. Adjust the height of your watering tube. 6. Add a drain hole to your new self-watering planter. 7.
Simply place all your plants in a plastic kiddie pool and then fill it up with 2 -3 inches of water! I would suggest doing this in the shade of course and also be sure to remove the saucers from under the potted plants to ensure that they can easily drink the water!
You can use gravel, which is heavy and cheap or you can use perlite which is light and much more expensive. Both are functionally similar. They create large air spaces which you fill with water and the more water you have in the reservoir, the longer it is between each time you need to water the pot.
The only reason to put a rock in the bottom of the planter is to cover the drainage hole and keep soil from coming out when you water your plant. Only use one rock per drainage hole.
The disadvantages of automatic irrigation are: costs for purchasing, installing and maintaining the equipment. reliability of irrigation system (due to human error when setting up) increased maintenance of channels and equipment to ensure it is working properly.
Using Terra Cotta Watering Spikes
This works in a similar way to the traditional olla, but instead of the water being contained within the olla, the bottle acts as the reservoir. The narrow nature of the spikes makes them ideal for use in tighter spots or in containers.
Potted plants and hanging baskets are more of a concern. These can wilt after just a day or two without water, especially in a hot, sunny spot and especially when recently planted.
You can use a 2-liter or 20-ounce soda bottle. The smaller bottles work better for container plants. Punch 10-15 small holes all over the bottom half of the plastic bottle, including the bottom of the bottle. You can then place the plastic bottle in the sock or nylon.
With capillary wicks, the water rises through small channels in the wicking material. In one test I performed, water in a 7/16-inch washed solid-braid nylon rope rose 10 inches in 100 minutes and 22 inches in 20 hours. Capillary wicks are a popular way to water houseplants and starts.
The disadvantages of using a self-watering pot
Water-hungry plants, such as aquatic plants that need consistently moist soil, will not thrive in a self-watering pot. Conversely, those that prefer their soil to dry out between watering, such as cacti, succulents and orchids, may also find it difficult to thrive.
Keep Outdoor Plants Watered with Plastic Bottles
Or, simply replace the caps with funnel-shaped spikes, available at your local garden center. Water your plants well, then fill the plastic bottles. Screw on the caps or irrigation spikes, and push the bottles upside-down into the soil next to your plants.
The first thing is to get hold of some material to use as the wick. Nylon or polyester braided rope is ideal (polyethylene is hydrophobic and so not a good choice).
Drip irrigation can be more efficient because water is slowly and directly applied to plant root zones, minimizing evaporation and runoff.
To answer simply, yes, watering globes are good for plants. Plant watering bulbs are a great addition to any gardener's supplies.
The bottom line is that, while self-watering planters have some issues to iron out, they're not the world's worst option for plant care.

Houseplants: Popular houseplants like peace lilies, African violets, ferns, snake plants, and pothos are well-suited to these planters.
Place a thin layer of gravel at the bottom of the planter. This will provide emergency drainage in case of over watering. To prevent the soil from entering the gravel section, place the filter fabric cloth over the gravel.
Close the bottle tightly and fill it through the U-shaped hole. Fill the bottle until the water level reaches ½ to 1 inch (1.27 to 2.54 centimeters) below the bottom row of holes. If you want to, you can even add some water-soluble fertilizer to the water. Tilt the bottle over your plants to water them.
Start with a 1/32 inch drill bit and place one or two holes in the center of the bucket. If you don't have a drill, you can also use a hammer and a nail. The next step is to position the bucket over the root zone next to the tree or plant that needs a deep watering, and fill with water.
