With the grow boxes filled with medium and seedlings transplanted our next project was the completion of the automated watering system. Lesson 16 in the MGC book, page 125, covers the construction details of the automated watering system. Three holes were drilled every 4 inches of the 3/4 inch schedule 30 pvc pipe to water our grow box. The holes are small, we ordered the number 57 drill bit from Amazon as our local stores don’t carry anything so small.
The holes are positioned to get a stream of water to squirt straight down into the bed and the other two at an angle towards the outside of the box. Our system will be drained in the winter as it turns cold. For all the piping that is below ground we elected to go with schedule 40 to help ensure we don’t have to dig up a broken pipe.
Currently we water by connecting a garden hose to the system. At some point we may go high tech and use a truly automated system.
