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 or smaller garden beds that might otherwise be handled by a Grow1 Hand Sprayer 64 oz. It is 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. If you prefer automated pressure, consider the Grow1 Power Sprayer Max 5L for a similar capacity without the manual pumping.

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 Grow1 Backpack Sprayer 4 Gallon.

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 than the Grow1 Pump Sprayer 3 Gallon, making it easier to carry for quick jobs where a larger 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. For users who prefer a rolling option, the Grow1 CropMate Mini offers similar pressure with the convenience of wheels.
