TORUS AUTO pH Controller 380L - Hydroponics | BloomLED

TORUS 380L Automatic pH Controller: perfect pH, effortlessly

The TORUS AUTO pH Controller 380L continuously stabilises the pH of your nutrient solution — with no pump, no probe and no electricity. Built for reservoirs up to 380 litres, it keeps your hydroponic crops in the ideal nutrient-uptake window, week after week.

In indoor growing, the pH of the nutrient solution is the single most decisive — and most unstable — factor. As soon as it drifts outside the 5.5–6.5 window, key elements become locked out: plants show deficiencies and stalled growth even though the reservoir is full of nutrients. The TORUS PerfectPH 380L fixes this at the source through passive buffering: a regulating agent gradually releases what is needed to neutralise drift and naturally pulls pH back to target. No electronics, no daily adjustment, no probe to calibrate.

In practice, you simply place the controller in your reservoir and you're done. It works around the clock to absorb the pH swings caused by nutrient uptake, evaporation and top-ups. You save a huge amount of time and eliminate the dosing errors that come with manual pH Down or pH Up. For growers running several systems or away for a few days, it brings complete peace of mind.

The TORUS PerfectPH 380L is part of a complete range of automatic controllers. Whether your reservoir is smaller or larger, BloomLED offers a model for every volume, along with the PerfectPH refills you need to extend the controller's action season after season. Selected and shipped by BloomLED, an indoor-growing expert for over 10 years.

Setup and best practices

Getting started is instant: unpack the controller, remove the PerfectPH cartridge seal and place the unit directly into your nutrient reservoir. No connections, no initial settings. Over the first few hours the pH gradually moves toward target; you can check it with a pH tester to confirm stabilisation. For best results, stir the solution gently when changing tanks and make sure the controller stays fully submerged at all times.

Over the weeks, the buffering agent is naturally used up: when you notice the pH starting to drift more, it is the sign that a PerfectPH refill is due. Expect 8 to 12 weeks on average depending on your water hardness and how much your plants drink. By keeping a spare refill on hand, you guarantee uninterrupted regulation across the whole growth and flowering cycle. It is this ease of use, combined with proven reliability, that makes the TORUS 380L the ally of demanding growers.
