Designing a custom watering system for your greenhouse is never an easy task. There are so many different types to choose from depending on what you are planning to grow. The first thing to decide on, of course, is what types of plants you are planning to nurture, because the type of watering system you will ultimately need is greatly determined by the types of plants most often grown in your greenhouse. For example, tropical plants require more water and often grow best with a misting delivery system. Ask yourself if the plants you are growing will grow best with a drip irrigation system, a misting system or even a running water system. Each system has it’s own unique features and setup that help you achieve the perfect balance of water to your greenhouse, and keeps from wasting water.
Drip System – A drip watering system usually sets down in the pot or soil and has a slow, steady drip that keeps plants moist without over watering the soil. Drip systems are usually made from hoses or bottles with tiny holes. The holes in hoses cause a high surface ratio and only allow small amounts of water through. If you don’t have the means to buy a drip system, you can always make one out of a gallon jug or a 2-liter bottle. By cutting a few holes in the cap of the bottle and a few around the sides of the bottom, you can make your own drip system that will keep your plants well watered even if you forget about them from time to time.
Misting System – These systems are good to use for plants that only need a small amount of water, such as cacti because their root systems make the most of any water applied. In addition, these can help to cool your greenhouse and add humidity in dry climates.
Running Water – Running water systems are probably the easiest to fabricate and can be made using PVC pipe, just like any other irrigation system. A great idea for the running water systems is to use barrels to collect rainwater. This is a great way to water your plants by conserving water and cutting down on the costs of upkeep. When designing your running water system with rain barrels, be sure to put in a good working valve so that you can retain all of the water you catch from the rain.
Greenhouse watering systems can be as unique as the gardener who is using them. There are many different types and uses and can either be pre-made or designed yourself. It is best to keep the plants together which have the same basic watering needs, just to make it easier to adequately water each plant. If all else fails, consult your local gardening expert to help determine which type of watering system is right for you and you might be surprised to find they could already have a system drawn out that fits your eco-friendly watering system needs.
