If you are living in a drought-hit area, then you may need a slow drip irrigation system to help your gardening efforts. With a drip irrigation system, you wouldn't need to water your plants every day. You would not need to worry about watering your plants while you are on holidays. With some modifications, you can also turn these drip irrigation systems into your own slow releasers of liquid fertilizers, which are not available in the market yet.
But many commercial systems of this date, like drip springer, can cost several thousand dollars each. Perhaps, if you are open-minded, you may be interested in the following inexpensive solutions:

All these systems cost almost nothing to make. They need no electricity to operate. In addition, they are now in the public domain. If you seriously care about the environment, then why waste your time and money on those inefficient proprietary systems?
