How to build an Aeroponic system, Step 3

Measure and drill five equally spaced holes along the top of the assembled manifold. If you can find the exact size drill bit the micro spray jets can usually be threaded into the holes very tightly creating a leak proof seal. If you make the holes to big the micro spray jets will not fit properly and will need to be glued. The best size drill bit I have found for this step is 5/32". This is a very lightly used drill bit that is very sharp. The size needed will vary between manufacturers of both micro spray jets and drill bits.

Tip* You can find the appropriate sized drill bit by comparing the end of a drill bit to the end of the spray head. You will want to use a drill bit that is slightly smaller than the threads on your spray heads.
