Nutrient Pump, 30 ml

Spill-Free Pump Dispenser for Nutrient Containers

Lifting and pouring a full nutrient jug for every dose is a common way to spill concentrate or misjudge an amount. This nutrient pump screws onto the lid of a 1-gallon container and works like the pump on a body wash or soap bottle, letting growers dispense a controlled amount without lifting the container at all.

A full pump stroke delivers 30 ml, or a partial pump can be used to dispense a smaller amount, and the pump also fits some 2.5-gallon nutrient containers.

Key Features & Benefits

Frequently Asked Questions

How much liquid does a full pump dispense?

A full pump stroke dispenses 30 milliliters. This gives a consistent, repeatable dose without needing to eyeball a pour.

What size container does this pump fit?

It screws onto a 1-gallon container lid, and also works on some 2.5-gallon nutrient containers. Confirm your container's thread size fits before relying on it as a fixed part of your dosing routine.

Can I dispense less than a full pump?

Yes, a partial pump stroke dispenses a smaller amount than the full 30 ml. This gives some flexibility for finer dosing adjustments.

How do I know if it fits my 2.5-gallon container?

Fit varies by container thread pattern, so it is worth test-fitting the pump on your specific 2.5-gallon jug before assuming compatibility. Not every 2.5-gallon nutrient container uses the same lid thread.
