THROUGH THE Cultivator's LENS Hands-On Evaluation

  • You are spot treating small beds because a large backpack sprayer is too heavy and awkward for quick tasks.
  • You are looking for precise foliage feeding because you need a steady, controlled mist rather than a heavy soak.

  • The locking trigger saves your grip strength during longer sessions, which makes a huge difference.
  • That five-foot hose is surprisingly useful because it lets you set the tank on the floor while you reach high.

  • Gardeners who used this for routine maintenance report that the pressure release valve makes clean-up much safer.
  • Users report that the manageable size helps them carry the unit around the garden without fatigue.

Grow1 Pump Sprayer 1 Gallon (4L)

Not every job needs a big tank strapped over your shoulder. The Grow1 1 Gallon Pump Sprayer keeps things compact and manageable, sized for quick spot treatments, smaller garden beds, or spraying tasks that don't call for the bulk of a larger unit. It's built from the highest grade polyethylene plastic, resisting corrosion from insecticides and herbicides, and works just as well with water, fertilizers, pesticides, cleaning detergents, and solvent-free preservative treatments.

An on/off trigger with a convenient "on" lock keeps your hand from tiring out during use, letting you hold a steady spray without constantly squeezing. A heavy-duty 5-foot hose extends your reach for a unit this size, and the adjustable 29-59 PSI pump lets you dial in pressure for the task, whether that's a gentle mist for foliage or a firmer stream for spot treatments.

A safety and pressure release valve adds an extra layer of control once you're finished spraying, and the convenient carrying strap makes the lightweight tank easy to sling over a shoulder or carry by hand. It's a practical, no-fuss option for growers and homeowners who need reliable spraying power without the size of a full backpack unit.

Frequently Asked Questions

How does this compare to the 3-gallon Pump Sprayer? +

Both share the same on/off locking trigger, safety valve, and 29-59 PSI adjustable pump, but this 1-gallon model is smaller and lighter, making it easier to carry for quick jobs where a 3-gallon tank would be more than you need.

What can I spray with this pump sprayer? +

It's designed for water, fertilizers, herbicides, and pesticides, as well as cleaning detergents and solvent-free preservative treatments. The polyethylene tank resists corrosion from these chemicals.

How much solution does the tank hold? +

The tank holds 1 gallon, or about 4 liters, of solution — a compact size suited to smaller jobs and quick spot treatments.

What does the "on" lock on the trigger do? +

It lets you hold a continuous spray without constantly squeezing the trigger, which reduces hand fatigue during use.

Can I adjust how much pressure the sprayer puts out? +

Yes, the pump operates across a 29-59 PSI range, so you can dial in lighter pressure for delicate foliage or higher pressure for tougher applications.

Is the sprayer easy to carry during use? +

Yes, its lightweight, compact design paired with the carrying strap makes it easy to sling over a shoulder or carry by hand throughout the job.
