Dosatron Hobby Cultivator Expansion Doser

The Hobby Cultivator Expansion Unit allows you to adapt your multi-pump system by adding more pumps based on the needs of your application. The Hobby Cultivator Multi-Pump System leverages Dosatron’s unique, water-powered dosing technology to deliver the optimum blend of nutrients and fertilizers directly to your plants. Applications include liquid fertilizer programs, powder fertilizer programs, concentrated liquid organics, enzymes and beneficial bacteria, propagation and rooting, sanitation, line cleaning, and adjusting pH up or down.

Engineered specifically for indoor home grows and basement grows, the Hobby Cultivator is perfect for applications with an average of four to six lights or 12 to 96 plants. The standard system comes with four Dosatron pumps but is easily adapted by adding more pumps based on the needs of the application. It can be used with a direct injection approach or alongside small batch tank systems and recirculating water cultures.

The Hobby Cultivator was designed based on feedback from hobby growers worldwide – people who are passionate about their plants but don’t want to be attached to them 24/7. With the Hobby Cultivator, you can leave your grow knowing Dosatron will continue providing simple, reliable, and repeatable results. Your plants don’t take days off, but luckily neither does Dosatron.
