RETAIL

We carry fertilizer injectors at three levels.
The simplest is the EZ-Flo, popular with backyard gardeners.
The Mazzei is a Venturi style injector that works by creating a pressure differential.
The Mixrite is a commercial grade injector that accurately meters out the fertilizer.
The Fertilizer Calculator at the bottom of this page can help you assess your fertilizer requirements.
