Grow1 Pump Sprayer - 4L/1 Gal - 5 ft Hose - 29-59 PSI

Hands-Free Spray Runs for Grow Rooms and Gardens - 4L Tank

Spraying plants with a handheld bottle means constant refilling and a tired grip. The Grow1 Pump Sprayer holds 1 gallon, so you can treat more plants per fill. A lockable trigger holds the spray on, and the polyethylene tank is built to resist corrosion from common garden treatments.

This 1 gallon size suits hobbyists and regular indoor growers who need more capacity than a bottle without carrying a large backpack unit. It is a good fit for foliar feeding, watering and routine treatments in small to mid-size spaces.

Key Features & Benefits

• 1 gallon tank — covers more plants per fill than a handheld bottle.
• On/Off trigger with "on" lock — holds the spray steady without a constant squeeze.
• 5 ft hose — lets you reach plants while the tank stays on the floor or on your shoulder.
• Safety and pressure release valve — lets you relieve pressure from the tank after use.
• Carrying strap — makes the sprayer easier to move between rooms.

Who Should Use Grow1 Pump Sprayer

Home gardeners, hobby growers and small commercial operations that apply water, nutrient solutions or other treatments to plants. It also works for cleaning solutions around the grow space.

A: The tank holds 1 gallon, which is about 4 liters. That is enough to treat a good number of plants before refilling.

Q: What can I spray with it?
A: It suits water, fertilizers and other plant treatments, as well as cleaning solutions. Always follow the label on any product you apply and rinse the tank after use.

Q: What does the pressure release valve do?
A: It lets you vent built-up pressure from the tank. Release pressure before opening the tank or storing the sprayer.

Q: How does this compare with a handheld spray bottle?
A: A pump sprayer holds far more liquid and builds pressure for a steady spray. The hose and trigger also reduce hand fatigue over longer sessions.

Q: What is the operating pressure?
A: The sprayer works in a range of 29-59 PSI. You pump the handle to build pressure and the trigger controls release.
