At BloomLED, an indoor-growing expert for more than 10 years, we selected the TORUS 380L INLINE automatic pH regulator for growers who want perfectly controlled pH without daily monitoring. Built for hydroponics, this passive stabilizer keeps your nutrient solutions in the ideal uptake range, day after day.
pH is the invisible conductor of every hydroponic grow. When it drifts, your plants lose access to essential elements such as iron, calcium and magnesium, even when your nutrients are dosed perfectly. The TORUS 380L INLINE solves the problem at its root: thanks to its passive regulation technology, it continuously corrects pH swings in your reservoir and holds the solution within a nutrition-friendly range, typically between 5.5 and 6.5 in hydroponics.
The INLINE version stands out because it installs directly into the irrigation circuit. Instead of simply being submerged, the TORUS unit is plumbed in-line on your recirculation loop, ensuring constant contact between the solution and the regulating media. The result is smooth, even pH control with no sudden spikes or drops, ideal for recirculating hydroponic systems up to around 130 litres (35 gallons).
| Feature | Detail |

| Application | Hydroponics, growth and flowering |
| Installation | In-line on the recirculation circuit |
No dosing pump, no electronic probe to calibrate: the TORUS stabilizes pH through passive chemistry. You gain reliability and remove a potential point of failure from your setup.
The system runs without any power supply. That means real energy savings and extra safety during a power cut, exactly when electronic regulation would stop protecting your crop.
Plumbed directly onto your recirculation loop, the TORUS stays in permanent contact with the solution, so regulation is more even than with a unit simply dropped into the tank.
Optimized for recirculating hydroponic systems, it suits both the growth phase and flowering, when nutrient demand shifts and pH stability becomes critical.
By holding pH in the ideal window, the TORUS keeps every element of your feed bioavailable. Fewer deficiencies, more vigorous plants and more consistent yields.
With no electronics or complex mechanism, the TORUS needs very little attention. An occasional check of the regulating media is enough for weeks of peace of mind.
For demanding growers, passive pH regulation is a genuine paradigm shift. No more manual pH-down corrections every morning, no more stress over overnight drift: the TORUS 380L INLINE works in the background, around the clock, to give your roots a stable chemical environment. That consistency translates directly into more uniform growth and more predictable harvests.
BloomLED selected the 380L INLINE version specifically for serious setups. If your reservoir is smaller, the TORUS 260L automatic pH regulator may suit you better; and to calibrate your control pH meter, we recommend pairing it with a buffer calibration solution. Our team, based in France and passionate about indoor growing, is on hand to advise you on the right sizing.
The secret to a successful hydroponic grow is not just the nutrients: it is pH stability that truly unlocks nutrition. With the TORUS 380L INLINE, that stability becomes automatic.
Yes. Regulation is entirely passive: no pump, probe or power supply is required. The regulating media acts chemically on the solution, ensuring continuous protection even during a power cut.
What reservoir size can I treat?This version is designed for hydroponic and nutrient reservoirs up to around 130 litres (35 gallons). For smaller volumes, the TORUS 260L model is a better fit.
What is the difference between the INLINE version and a submerged model?The INLINE version connects directly to your recirculation circuit, ensuring permanent contact with the solution and therefore more even regulation. A submerged model is simply placed in the tank.
Do I still need to measure my pH?We always recommend an occasional check with a calibrated pH meter. The TORUS stabilizes pH, but regular monitoring lets you confirm correct operation and media wear.
Does the TORUS replace nutrients or pH correctors?No. It does not replace your feeding program; it keeps pH in the ideal zone so that feed is fully absorbed. It greatly reduces, or even removes, the daily need for pH down.
