Blumat Kit 12 Drips Complete
The Blumat Kit 12 Drips Complete is a gravity-fed, pump-free automatic watering system built around ceramic moisture sensors. Each sensor continuously monitors substrate VWC (volumetric water content) and triggers drip delivery only when soil moisture drops below the calibration threshold — stopping automatically once adequate moisture is restored. The complete kit covers 12 plants and includes sensors, 7m supply tubing, barrel connector and all fittings. Zero electricity, zero timers, zero over-watering risk. Compatible with soil, coco and peat substrates. Explore the Blumat system trusted by growers across Belgium and beyond.
Blumat Kit 12 Drips Complete — passive ceramic irrigation for precision growers
Photosynthetic efficiency is the single most impactful variable in any cultivation setup — and consistent substrate moisture is what drives it. The Tropf-Blumat system eliminates irrigation guesswork with ceramic sensors that react directly to soil water tension, not to a clock. No pump, no power draw, no programming. Just physics delivering water exactly when and where it's needed. Browse the full automatic irrigation range for more options.
How the ceramic sensor technology works
Each Blumat carrot is manufactured from microporous fired ceramic. As the surrounding substrate dries, osmotic tension inside the sensor increases, mechanically actuating a micro-valve that allows water to drip from the supply tube. When substrate moisture recovers to the set threshold, pressure equalises and the valve closes. This passive feedback loop operates continuously — no electricity, no moving parts, no maintenance cycles.
Kit contents and coverage
The Blumat Kit 12 Complete ships with everything needed to irrigate 12 plants (reservoir not included):
- 12 Tropf-Blumat ceramic sensors — each waters an 8–10 inch diameter zone
- 7 metres of 8mm supply tubing — flexible layout, cut to length
- 1 barrel connector for gravity tank installation
- 90° elbow, T-connector and end cap (8mm) — full fitting set
Installation requires scissors only. Mount your reservoir 20–100 cm above pot level, connect the tubing, insert sensors into substrate. Covers 4× 80cm planters, 3× 1m troughs or 12 individual pots (8–25 cm diameter). For larger containers, stack 2–3 sensors per pot for full coverage.
Performance comparison: Blumat vs active drip systems
Active drip systems like the Nutriculture Wilma XL 8 use timed pump cycles — effective, but dependent on accurate timer scheduling and pump reliability. The Blumat system removes both variables entirely: each sensor operates independently, meaning one dry plant triggers its own irrigation without affecting others. Substrate VWC stays within a tighter range, reducing osmotic stress and supporting more consistent uptake of nutrients. Ideal for mixed-variety grows where water demand varies by plant.

What reservoir height is required for the Blumat Kit 12 Drips Complete?
Position the reservoir between 20 cm and 1 metre above pot level. Lower placement reduces flow rate; higher placement increases it. For most setups, 40–60 cm above the substrate surface provides optimal drip rate. Fine-tune by adjusting the sensor depth within the substrate — deeper insertion slightly increases flow sensitivity.
Can the Blumat Kit 12 deliver nutrient solution, not just plain water?
Yes. The Blumat system is compatible with diluted nutrient solutions. Use EC levels appropriate for your crop stage and flush the ceramic sensors periodically to prevent mineral salt build-up in the micropores. Avoid high-viscosity additives or heavy organic teas which can clog the ceramic material over time.
How many Blumat sensors do I need per container?
One sensor per container up to 25 cm diameter. For containers between 25–40 cm, use two sensors placed on opposite sides. Containers over 40 cm diameter require three or more sensors for even moisture distribution. The 12-sensor kit in this configuration covers mixed pot sizes in a single install.
Is the Blumat system suitable for coco coir substrates?
Yes, coco coir works well with Blumat sensors. Coco's high air-to-water ratio means sensors may trigger more frequently than in soil — this is normal and beneficial for coco-grown plants which prefer more frequent, smaller irrigations. Ensure the coco is fully saturated on first install before inserting the sensors to calibrate the system correctly.
