Nebula Pump Spray Bottle – Water Master Electric Fogger 5L

The Nebula Pump Spray Bottle by Water Master is the ultimate electric nebulizer designed to professionalize the maintenance of your indoor or outdoor crop. This ULV (Ultra Low Volume) device transforms your foliar fertilizers and pest control solutions into a microscopic mist, ensuring total coverage without the fatigue of manual spraying.

Are you tired of battling pests with inefficient manual sprayers?

We have all been there: trying to cover a dense canopy with a cheap hand sprayer, pumping until our wrists cramp, and watching big droplets roll off the leaves onto the floor. It is messy, exhausting, and often leaves parts of the plant completely dry and vulnerable to attacks.

This inefficiency is not just annoying; it is dangerous for your harvest. Uneven spraying means spider mites and thrips survive in the dry pockets you missed. Furthermore, large water droplets can cause the "lens effect," burning your leaves under the grow lights, or create excess humidity that invites mold like botrytis to the party.

The solution is upgrading to the Nebula Pump Spray Bottle. By switching to an electric ULV system, you generate a penetrating fog that wraps around stems and under leaves automatically. It turns a stressful, hour-long chore into a quick, effective 10-minute task, ensuring every millimeter of your grow is protected.

How your crop maintenance changes once you add it

The difference between a standard sprayer and the Nebula is night and day. Visually, you stop seeing wet, dripping plants and start seeing a fine, cloud-like mist that settles gently on the foliage. This "cold fog" behaves like a gas, floating into the deepest parts of the plant structure where pests love to hide, areas that manual sprays simply cannot reach.

Practically, your workflow becomes faster and more professional. You no longer need to move every single pot to reach the back; the powerful adjustable flow projects the mist exactly where you need it. You save on product because the micro-droplets adhere better to the leaf surface, meaning less runoff and more absorption of your expensive nutrients or insecticides cannabis.

What you can apply with this electric fogger

This device is incredibly versatile and compatible with almost any liquid product you need to use in your grow room or garden. Here is what you can manage with it:

• Pest Control: Apply neem oil, potassium soap, or chemical insecticides with total precision.
• Foliar Feeding: Spray cannabis fertilizers and stimulants for immediate absorption through the stomata.
• Disinfection: Use it to sanitize your grow tent or room between cycles (using diluted bleach or specific cleaners).
• Humidity Control: In a pinch, it can act as a manual humidifier to quickly raise RH levels.
• Fungicides: Prevent powdery mildew by creating a protective layer over the entire plant.

Steps to achieve the perfect foliar application

1. Prepare your mix: Dilute your product in water according to the manufacturer's instructions before pouring it into the tank.
2. Fill the tank: Pour the solution into the 5-liter reservoir and close it tightly.
3. Adjust the flow: Set the regulator to your desired droplet size (smaller for fog, larger for heavier spray).
4. Position yourself: Stand at a distance where the mist expands before hitting the plants.
5. Spray: Turn it on and move the nozzle in sweeping motions, ensuring the mist drifts into the canopy.
6. Clean: Always run clean water through the system for a minute after use to prevent clogging.

Advantages and benefits of ULV technology

• Maximum Coverage: The 10–160 µm droplets cover more surface area with less liquid.
• Zero Fatigue: The electric motor does the work; you just aim.
• Adjustable Power: Control the flow rate between 50 and 260 ml/minute depending on the density of your crop.
• Lightweight Design: At only 2.6 kg, it is easy to maneuver around your grow space.
• Economic Efficiency: You use less fertilizer and pesticide because less is wasted on the floor.

Frequently Asked Questions

What is the capacity of the tank?

The Nebula features a generous 5-liter tank, which is usually enough to treat a large indoor room or a medium-sized outdoor garden without needing to stop and refill constantly.

How fine is the mist it produces?

It produces droplets between 10 and 160 microns. The lower setting creates a fog-like mist (ULV) ideal for pests, while the higher setting is wetter, suitable for cleaning or heavy foliar feeding.

Can I use it for outdoor plants?

Absolutely. While it is a favorite for indoor growers due to its precision, it works perfectly outdoors. Just make sure you have an extension cord if you are far from a power outlet.

Is it hard to clean?

Not at all. The most important step is to spray fresh water through it after every use to keep the nozzle and internal tubes free of residue or salt buildup.

Personal Experience of Pevgrow’s CEO (Alan)

I used to dread foliar application days. My hand would cramp up halfway through the room, and I always felt like I was drowning the plants rather than treating them. Since I switched to the Nebula Pump Spray Bottle, the game has changed completely. It literally takes me 5 minutes to do what used to take 45.

My personal trick? I use it on the finest setting to apply preventive organic fungicides. The mist is so fine it coats the underside of the leaves perfectly without leaving them soaking wet, which is crucial to avoid mold issues during the transition to flowering. It’s one of those tools that pays for itself the first time you save a crop from spider mites.
