Dosatron 0.03 to 0.3% Proportional Fertilizer Doser – No Electricity Needed

The Dosatron 0.03 to 0.3%-1.25 to 11 Ml is a water-powered proportional doser that automatically mixes your fertilizers with absolute precision, saving you hours of manual labor and guaranteeing a flawless feeding schedule for your cannabis plants.

Are you still wasting time measuring nutrients by hand and constantly checking levels with your Bluelab meters to avoid nutrient burn?

Manual mixing is not just tedious; human error can easily lead to overfeeding or underfeeding, stressing your plants and ruining your harvest. Plus, relying on electric pumps means a simple power outage could leave your hydroponic setup completely dry and your crop ruined.

Enter the Dosatron. This mechanical beast uses your water line's pressure to inject the exact amount of nutrients your crop needs. No cables, no math, just perfectly balanced feeding every single time.

Automated, precise, and electricity-free cannabis nutrition

This device connects directly to your water line and acts as the heart of your irrigation setup. As water flows through, it pulls the exact ratio of liquid fertilizer and mixes it uniformly before sending it to your plants. Whether you are running a complex hydroponic system or a simple soil drip line, it ensures your weed gets the exact diet it needs to thrive without any guesswork.

Key features and benefits of the Dosatron 0.03 to 0.3%

• Water-powered operation: It runs entirely on water pressure (4.3 to 85 PSI), meaning zero electricity costs and no risk of failure during power outages.
• Surgical precision: Adjustable dilution range from 1:3000 to 1:333 (0.03% to 0.3%), ensuring your plants get exactly 1.25 to 11 mL of nutrients per gallon of water.
• Heavy-duty build: Made from highly durable polypropylene, it resists harsh chemicals and fertilizers, guaranteeing years of reliable use.
• High compatibility: With a standard 3/4” NPT connection and a flow rate of 0.05 to 14 GPM, it easily integrates into almost any Dosatron setup or custom irrigation line.

How to install and use your Dosatron doser

Setting up this doser is straightforward, even if you aren't a plumbing expert. Just follow these simple steps to automate your grow room:

1. Connect the Dosatron directly to your main water supply line using the 3/4” NPT fittings.
2. Drop the suction hose into your concentrated fertilizer tank.
3. Twist the adjustment sleeve to set your desired dilution ratio (from 1.25 to 11 mL per gallon).
4. Turn on the water. The internal piston will start clicking, automatically mixing and distributing the nutrient solution to your plants.

Frequently Asked Questions

Does the Dosatron need to be plugged into an outlet?

Not at all. It is 100% powered by the kinetic energy of the water flowing through your pipes. This makes it incredibly safe for wet environments and immune to power cuts.

Can I use thick organic fertilizers with it?

While it handles most liquid nutrients perfectly, very thick or sludgy organic fertilizers might clog the internal filter. It is highly recommended to use well-filtered or mineral-based nutrients for optimal performance.

How often does it need maintenance?

It is a very low-maintenance device. However, it's good practice to flush the system with clean water between grow cycles and replace the internal seals once a year to keep the suction strong and accurate.

Personal Experience of Pevgrow’s CEO (Alan)

When I first upgraded my indoor setup to a fully automated drip system, mixing nutrients manually became a massive bottleneck. I was spending hours measuring out mLs, checking pH, and worrying if the mix was homogenous. Installing the Dosatron completely changed the game for me. It’s literally a "set it and forget it" piece of gear.

I usually run it at a low dilution rate for my vegetative stage and dial it up slightly when the girls hit flowering. The best part? I sleep peacefully knowing that even if there's a storm and the power goes out, as long as there's water pressure, my plants are getting fed. It’s an absolute must-have if you want to scale up your grow without losing your mind.
