Dosatron 0.2% - 2% Fertilizer Injector · Automatic Water-Powered Nutrient Doser for Hydroponics

The Dosatron 0.2 to 2% - 7.5 to 75ml is the ultimate automatic fertilizer injector that transforms your irrigation system by delivering perfectly mixed nutrients using only water pressure, completely eliminating the hassle of manual measuring.

Picture your typical feeding day: you are surrounded by sticky bottles, syringes, and measuring cups, trying to calculate the exact milliliters for your reservoir. One small math mistake or a slip of the hand, and you have just burned your plants or thrown off the delicate balance of your entire crop.

It is frustrating and incredibly time-consuming. Spending hours hunched over a water tank, constantly adjusting, stirring, and testing takes the chill vibe out of growing. Plus, as your garden expands, this manual mixing becomes a massive bottleneck that keeps you tied to your grow room, wasting expensive fertilizers and your precious free time.

Enter the Dosatron 0.2 to 2%. This genius device hooks directly into your water line and uses the flow of water—zero electricity needed—to siphon and mix your liquid nutrients with surgical precision. You just set your desired ratio, turn on the tap, and watch your plants get perfectly balanced meals every single time, giving you back your freedom and peace of mind.

What this automatic doser includes and delivers exactly

Built for both hobbyists and commercial growers, this robust piece of engineering is designed to handle the heavy lifting of your daily feeding schedule. Here is what makes it tick:

• Proportional dosing mechanism: Injects nutrients at a precise ratio of 0.2% to 2% (2.0 to 20 ml per liter), adjusting automatically to changes in water flow or pressure.
• Hydraulic motor: Operates entirely on water pressure (4.3 to 85 PSI), meaning no cords, no plugs, and zero risk of electrical shorts in a wet environment.
• High-strength polypropylene body: Highly resistant to corrosive chemicals and heavy fertilizers, ensuring years of reliable use.
• Complete installation kit: Includes the suction tube, mounting bracket, and a weighted filter to drop straight into your nutrient jug.

How your feeding routine changes from now on

Once you install this beauty, your daily grow room chores drop dramatically. You no longer need to play mad scientist with a dozen pipettes. Instead, you simply prepare a concentrated stock tank, set your desired injection rate on the dial, and let the water pressure do the rest. The mixture is homogenized perfectly before it ever reaches your plants.

If you run a hydroponic or aeroponic setup, this consistency is a game-changer. Your plants receive the exact same EC level at every single watering, preventing nutrient lockout and explosive pH swings. The result? Faster vegetative growth, fatter buds, and a much more relaxed grower.

Plus, the built-in bypass system means you can easily flush your lines with plain water without having to dismantle your plumbing. It is all about working smarter, not harder, so you can spend more time admiring your canopy and less time scrubbing reservoirs.

Advantages and benefits you’ll notice from day one

• Because it operates on water pressure, you can install it anywhere without needing electrical outlets, which means total freedom and safety in wet grow room environments.
• Because it features an adjustable 0.2% to 2% dial, you can fine-tune the exact amount of fertilizer injected, which means you avoid nutrient burn and maximize your yield potential.
• Because it mixes proportionally to the flow rate, the nutrient ratio remains constant even if your water pressure fluctuates, which means your plants get a perfectly balanced meal every time, reducing stress and boosting growth.
• Because it eliminates manual measuring, you stop wasting spilled nutrients and guessing dosages, which means you save money on expensive fertilizers and reclaim hours of your week.
• Because it is built with chemical-resistant polypropylene, it withstands harsh pH down liquids and thick organic syrups, which means you get a durable, long-lasting tool that will not degrade over time.

Tips to combine it with other Pevgrow products

To get the absolute most out of your automated feeding system, pairing it with the right gear is essential. Here is how you can build the ultimate lazy-grower setup:

• Premium Nutrients: Hook it up to a high-quality, highly soluble base nutrient like Cultivator Series Bloom Advanced Nutrients to ensure smooth injection without clogging the internal pistons.
• Continuous Monitoring: Place a Bluelab combo meter downstream to keep a constant eye on your pH and EC levels, ensuring the doser is hitting your exact targets.
• Inline Filters: Always use a good mesh filter before the water enters the unit to catch any sediment from your tap water, protecting the motor's lifespan.

Frequently Asked Questions

Is it hard to install the Dosatron in a standard grow tent?

Not at all! It easily splices into standard PVC or flexible tubing. Just make sure you install it in the correct direction of the water flow (indicated by an arrow on the body) and use a pressure regulator if your tap water exceeds 85 PSI.

Can I run thick organic fertilizers through it?

Yes, but with a caveat. While it handles most liquids beautifully, extremely thick or sludgy organics might require you to dilute them into a stock solution first. Always remember to flush the system with clean water after running heavy organics to prevent biofilm buildup.

How often does it need maintenance?

It is a workhorse, but it does need a little love. We recommend checking the suction tube filter regularly and replacing the internal seals (mini-maintenance kit) once a year if you run it continuously, just to keep the suction strong and accurate.

Do I need a separate unit for pH adjusters?

If you want to automate both nutrients and pH, yes. You would run them in series (one unit for nutrients, followed by another for pH down). Never mix concentrated nutrients and raw pH down in the same stock tank, as they will precipitate and lock out.

Personal Experience of Pevgrow’s CEO (Alan)

I remember the exact moment I decided I was done with hand-mixing. I was running a 4-light setup, spending over an hour every couple of days just measuring out micro, grow, and bloom bottles. My back hurt, my hands were stained, and I was constantly second-guessing my math. Installing my first Dosatron felt like stepping into the future.

I set up a 50-liter stock tank, dropped the suction hose in, dialed it to 1%, and turned the valve. Watching the water flow out perfectly mixed, hitting my target EC dead-on, was a revelation. It literally gave me my weekends back. My biggest tip? Always install a bypass valve loop. It makes it incredibly easy to flush your drip lines with pure water at the end of the flowering cycle without having to unhook the unit. If you are serious about scaling up or just value your free time, this is the best investment you will make for your grow room.
