Take a close look at all the advantages when using Add-It® or Green Machine Pro® fertilizer injectors!:

• Very easy to install and simple to operate. Fill the unit with a premixed solution of your favorite totally water-soluble fertilizer. Then walk away and forget it. When the irrigation system goes on, water and nutrients are sent to all the plants in the irrigation system. Surfactants (wetting agents) can also be injected to aid in breaking-up compacted soil, root hormones and micro-nutrients to stimulate plant growth, and Vitamin B-1 when transplanting trees and shrubs.
• Available in many sizes: pint, quart, 1/2, 1, 2, 3, 5 and 10 gallon capacity. They are self-contained. Nothing else is required.
• Totally proportioning (same injection rate from start to finish). Through a unique patented, hydraulic design, a small amount of water is diverted from the main stream of water and forced into the top of the additive tank. An equal amount of fertilizer is drawn from the bottom of the tank, and then forced back into the main stream of water. Distributes fertilizer evenly throughout the irrigation system. It’s amazing, yet simple!
• Add-It® and Green Machine Pro® can operate under constant mainline pressure up to 125 psi*. (*Except for small pint Add-It® injector, model AFI 5016-H, rated at 60 PSI.) They can be installed before a manifold of valves or after individual valves. Click here for ADDIT-size-flow-rate table
• There are no moving parts and nothing to wear out, like other injectors that have gear-driven electric or hydraulic motors or pumps, which eventually will wear out requiring maintenance and/or replacement..
• Easy to drain and refill. No messy tubing or wiring to trip over or unhook to refill.
• There is no pressure loss, and no electricity or other power source required for units to operate.
• Perfect for drip or sprinkler irrigation systems.
• Both Add-It® and Green Machine Pro® have received the prestigious AE50 award from the American Society of Agricultural Engineers (ASAE) for innovative product design.
• Durable, Dependable, Save time and money when fertilizing. Pays for itself in almost no time at all! Click here for ADDIT-size-flow-rate table
