SeedVUs fit into the distribution heads, and can be installed (or uninstalled) in a matter of a couple minutes for the entire drill. Quite unlike air diffusers that go into secondary lines so that there’s one for each opener: An all-day job to install, and a nightmare if they ever gunk up from seed treatments or fertilizer dust. The perforated mesh-type air diffusers in secondaries also have issues with very teeny seeds such as teff, an eastern Mediterranean grain crop related to sand lovegrass. When seeding these crops, diffusers must often be removed, or taped over (duct tape fixes anything, right? 🙂

SeedVU is the only device on the market that will stop excess primary-line backpressure, monitor for primary-line blockages, as well as reducing seed bounce. And, let’s face it, all air diffusers eventually have trouble with fertilizer or seed treatments gunking them up. For diffusers that install into secondary lines, this may cause a lot of down-time unplugging them, and in worst-case scenarios might be an all-day job to clean them up. But with SeedVU, it’s a matter of 2 minutes to remove all of them, put the old caps back on, and keep on seeding during crucial time windows. The same goes for ultra-small seeds (e.g., teff) that are unworkable in screen-type diffusers in the secondaries—rather than deal with 36 – 96 of them, just changing out a few SeedVUs has you on your way again!

Note: If you are replumbing your air drill (replacing primary & secondary hoses), try to situate the distribution heads as high as possible, and eliminate droops or horizontalness in all secondaries—this will let you discharge more air pressure from the SeedVUs, or any other diffuser for that matter.
