Envirogroom 1 Gallon Pump

The pump’s smart design delivers exactly the same amount every time, so I don't have to second-guess my measurements anymore. It fits my 1-gallon bottle perfectly and the whole thing feels built to last. Honestly, this is the little upgrade I didn't know I needed.

My mixing routine has gotten so much more accurate since I started using this pump. It locks into the bottle tightly and doesn't dribble or leak when I tilt it to pour.

The pump dispenses exactly one ounce per stroke, so I don't have to guess when mixing my nutrient solution anymore. It locks onto the gallon jug snugly and hasn't leaked a drop in three weeks of daily use. Exactly what I needed.
