Greenhouse Drip Irrigation

Step 1: Gather Information

1.How far is your water source away from your greenhouse?

This helps to estimate the amount of mainline tubing needed for your project. Remember with greenhouses there will also be mainline tubing along each wall, so you will be adding to this initial distance to determine how much mainline tubing you will need.

2.What are the dimensions of your greenhouse?

Knowing the dimensions of your greenhouse will let you know how much mainline tubing will be used in the greenhouse since the base of each wall will be lined with mainline tubing to create a square. To get the total amount of mainline tubing needed add the amount from question 1 to the amount found here in question 2.

3.How many plants do you wish to water?

Often in greenhouse plants are grown in containers and with this method it is easy to estimate the number of drippers you will need. Something to keep in mind regarding watering plants in a container is that if the container is large (over 12 inches) you may need multiple drippers per potted plant.

4.How much micro-tubing (feeder line) will you need?

There is no way to know exactly how much you will need. This is just an approximation. However, you can get close by knowing how many plants you have to water and then approximate the length of micro tubing you will run from your mainline tubing in order to reach each plant.

Step 2: Creating a sketch

We recommend creating a sketch of your project area. We have found that a sketch helps to visualize the area and ensures that you have not overlooked any detail.
