Hydrofarm HGNP 30ml Nutrient Pump
Just like the pumps you've used on body wash, soap and other household essentials, this pump makes it simple to deliver just the amount you need. No more spills from trying to lift and pour heavy canisters -- just screw this pump onto the lid of a one gallon container and pump away. It also works on some of our 2.5 gallon nutrient containers -- ask your Hydro farm product specialist. Pump down completely for a full 30 milliliter of nutrients, or do a partial pump to get just what you need.
