DIY Drip Irrigation System, Made from Plastic Bottles. The 'system' is super simple. All we have to do is grab some 2-liter plastic bottles, punch 2 holes into the sides and 2 into the bottom, and plant said bottles next to our plants. Fill them with water and our plants will get that slow watering they prefer. For more information about the project, visit Fine Craft Guild.

Recycled Drip Irrigation System - right-side up 2-ltr. bottle with 2 holes punched in the sides and 2 in the bottom. Plant it deep next to your plants you wish to water. By screwing the caps back onto the bottles after refilling, the water is released slower.
Drip irrigation reuse for Container Gardening: reuse a plastic bottle! "Leaving the bottle right-side-up and and poking the small hole(s) in the bottom of the 2 liter bottle, because then I can screw the cap back on and keep bugs, like mosquitoes, and garden debris out of the water reservoir"
