Time-controlled systems release a set amount of water at fixed times, regardless of conditions. They don’t adjust for sunlight, soil moisture, or the needs of individual plants. Tropf-Blumat, on the other hand, responds directly to soil moisture, watering only when your plants need it.
No. Leave the tap open. If rain provides enough water, Tropf-Blumat won’t release any.
At first, nothing happens. But if it stays off too long, the soil can draw water out of the sensor, letting in air and stopping the valve from working. Simply refill the Tropf-Blumat to reset it.
No. It’s designed for localized drip irrigation. Lawns require sprinklers, rain guns, or other large-area systems.
Yes. All water-carrying parts meet Austrian drinking water standards and are free of BPA and phthalates.
No. They’re safe for plants but not certified for use with drinking water.
Yes. Each Tropf-Blumat sensor controls watering independently.
The system works at max. 1.3 bar. Higher pressure risks blowing tubes off connectors
Hand-tight only. Never use tools, which can damage the thread.
The seal may be brittle. Replace the sealing filter (original or any suitable bathroom type). Avoid forcing the Pressure Reducer—it can damage the plastic thread. Also check the tap for corrosion, limescale, or scratches.
No. The 8 mm outflow can point in any direction.
That depends on plant numbers, their needs, and how often you want to refill.
Any material works. Use an opaque tank to prevent algae growth, and cover it with a lid to keep out insects or debris.
A few centimeters above the bottom so sediment stays out of the tubes. For large tanks, install a low outlet for easy flushing.
Every meter of height adds 0.1 bar pressure. A 12 m height equals 1.3 bar, the system’s maximum.
No, the new filter needs two side pegs to fit securely.
Yes. Just keep leaves and debris out. A water filter is recommended.
Avoid kinks, sharp bends, or tight pulls. Allow slack for winter contraction.
They damage the tubing. Use water or gentle heat (hairdryer) instead.
Up to 6 feet between the Tropf-Blumat and a T-piece/end-piece. Keep it unkinked, unobstructed, and that no objects are standing on it that would cut off the water supply.
No. The screw is factory-set. If one dripper is weaker, clean it.
Soak in warm water with vinegar or descaler. Use a toothbrush to remove buildup.
With hard water, limescale buildup is inevitable. Clean them more often.
By changing the drip tube length beyond the Tropf-Blumat:
• Shorter (min. 5 cm): soil stays drier
• Standard (8 cm): balanced
• Longer (max. 12 cm): soil stays wetter
Yes, but follow dosage carefully. Fertilizer may crystallize and clog tubes over time (expect replacement every 3–5 years). Annual chemical cleaning is possible—observe local regulations.
Possible with high-quality dosing devices (e.g. Dosatron). Same caution about clogging applies.
Yes, before the first frost.
They can stay outside.
They’re frost-proof but last longer if cleaned and stored dry in winter.
Often embedded in roots, so they’re built to stay put. Shut off water, drain the head, and reseal. If easy to remove, clean and store them like regular sensors
They are shiped closed. If the drip tube is stuck, it may be a gummed up section, so pull it out and massage it until free.
The membrane stiffens in colder weather. Close the screw slightly (2–3 markings).
Blumat uses the natural pull of the roots. Plants draw water directly from the porous clay cone. Once they’ve had enough, uptake stops and so does the water flow.
That depends on your plant’s needs and how long you’ll be away. Test the system for a while to gauge how often refills are needed.
Simply refill the container and the Blumat—no reset required
Yes, but clean the container and Blumat more often to prevent buildup.
Use opaque containers. Since algae needs light to grow, keeping the container dark prevents it.
No. A small air bubble won’t affect performance.
Water will flow constantly. This can be useful for very thirsty plants, but always use a saucer to protect against overwatering.
Yes. All Blumat Classic products meet Austrian drinking water standards and are free of BPA, PFAS, and phthalates.
No. While safe by standards, they are designed for plant watering and not certified for drinking water use.
If one isn’t enough, use several placed evenly around the plant. Be sure the water level in the container is lower than the Blumat so each draws only what the plant needs.
No, it’s not recommended for orchids.
Without a hole, a vacuum forms inside the bottle, and Blumat Easy will stop or slow down water delivery.
A tiny hole is enough—just use a pin. When refilling, you can cover it with your finge
That depends on the bottle size:
• With a 2-liter bottle, Blumat Easy lasts up to 10 days.
• With Blumat Easy XL, up to 7 days.
Bigger bottles can tip over, and their wider openings usually don’t fit Blumat Easy.
If the soil is very dry or the plant is especially thirsty, the roots pull more water from the clay cone.
The micropores may be clogged or algae has built up inside.
Once a year:
1. Soak in warm water for 5 minutes.
2. Clean inside with a small brush.
3. Sand the outside of the clay cone lightly.
No. Blumat Easy is designed for plastic bottles only.
Yes. All Blumat Easy products are tested to Austrian drinking water standards and are free of BPA, PFAS, and phthalates.
No. While tested to safety standards, they’re not certified for carrying drinking water—only for plant use.
The calibration is off and needs resetting. Unscrew the measuring head, hold the on button for 5 seconds until “ooo” appears, then refill with water, reassemble, and place it back in the soil
No. The moisture meter is splash-proof. Just avoid pouring water directly onto it to extend its lifespan. If you use the protective cap, direct watering isn’t a problem.
This is normal. The moisture meter slowly loses water and needs topping up once or twice a year. Check the white casing—if it’s half full, it’s time to refill.
It’s sturdy, but in dense or compact soil, loosen the soil first or make a hole using the Blumat corer, which is shaped to fit perfectl
No. The three screws on the bottom are intentionally unsealed to allow pressure equalization, which ensures accurate readings.
Moist air can enter and condense when temperatures drop quickly. This is normal and doesn’t affect performance. The display usually clears as it warms up. For faster drying, place it in a warm, dry area or unscrew it briefly.
Water may seep in through the screws. Open the moisture meter, remove the battery, and let everything dry completely before reassembling and checking function.
