Greeenhouse kits are designed to make it easy to install a professional drip irrigation system.

Our kits come complete with everything you need to create a working drip irrigation system and hook it up to any standard water faucet or garden hose.

Our greenhouse kits are designed to run mainline tubing around the base of each wall in the greenhouse, which allows for easy access from your mainline tubing to all your plants throughout your greenhouse.

How do you calculate total gallons per hour (GPH) in a drip irrigation system?

To calculate the total GPH running through your drip irrigation system you will need to add up all the

watering devices and their GPH ratings that you wish to install in your drip system. Below is an example:

     Bob has 100 drippers throughout his drip irrigation system. Forty are .5 GPH, another forty are 1 GPH      

     and twenty are 2 GPH. How many gallons per hour is Bob running through his drip irrigation system?

     40 x .5 GPH = 20 GPH

     40 x 1 GPH = 40 GPH

     20 x 2 GPH = 40 GPH

     Total GPH = (20 + 40 + 40) = 100 GPH

This means Bob could use ½” or ¾” tubing as his mainline tubing. However, 100 GPH exceeds the maxi-

mum GPH allowed for ¼” tubing, thus he could not use ¼” tubing as his mainline tubing.

Understanding the limitations for each size of drip irrigation tubing is critical in choosing the right drip ir-

rigation kit and something to keep in mind as you move through the rest of this guide.
