Ceramic-sensor drip valve for automatic plant watering. Each sensor reads soil moisture at the root zone, opens to deliver water when soil dries, and shuts off when moisture returns. Individually adjustable per plant. Works on gravity pressure alone with no electricity, timers, or apps. Reacts to weather automatically.
Soak both parts of each sensor in cool, non-aerated water for at least 15 minutes. Assemble the ceramic cone and green cap underwater to prevent air bubbles from getting trapped inside. If you spot a bubble, separate the parts and reassemble underwater again. Prepare your soil to the moisture level you want to maintain before installing. Insert the sensor near the root zone, then connect the 3 mm drip tube to your existing 8 mm supply line using the included T-piece. Open the adjustment screw until water flows, then slowly tighten clockwise until you reach a "hanging drop" -- water should just barely stop. Tighten two more arrow marks past that point. Come back in 12 to 24 hours and fine-tune from there.
Two Blumat Drip sensors, each with a 3 mm drip tube and an 8x8x3 mm T-piece for tapping into an existing 8 mm supply line. No supply tube, water source accessories, or fittings beyond the T-pieces are included. This is an expansion pack for an existing system.
Gardeners adding more plants to an existing Blumat Drip system. Also useful as replacement sensors when a cone gets damaged or for keeping spares on hand.

Installation Guide
How to Set Up Your System
Takes just a few minutes. Once set up, your plants water themselves.
Step 1
Prepare the Sensors
Separate the ceramic cone from the green cap. Soak both in cool water for at least 15 minutes. Use a pipette or your thumb to push water into the cap holes and flush out any trapped air. Reassemble underwater so no air gets sealed inside.
Step 2
Water the Soil
Pre-water the pot or bed thoroughly before installation. The sensor calibrates against the current moisture level, so the soil needs to be evenly moist at the start.
Step 3
Place & Connect
Push the ceramic cone into the soil near the root zone until it is fully buried. Cut your 8 mm supply line and insert the included T-piece. Attach the 3 mm drip tube from the sensor to the T-piece.
Step 4
Set the Flow
Open the adjustment screw counterclockwise until water drips visibly. Slowly tighten clockwise until you reach a hanging drop, then tighten two more arrow marks. That sets your baseline.
Important setup note
This 2-pack requires an existing 8 mm supply line and a water source already in place (either a raised reservoir with a tank connector or a hose with a Blumat pressure reducer). If you are starting from scratch, look at a starter kit instead.
First-water check
Come back in 12 to 24 hours. If the soil is too wet, tighten the screw clockwise. Too dry, loosen counterclockwise. Repeat daily until each sensor is dialed in. A Blumat digital moisture meter makes this faster and more precise.
PLANT DRIVEN WATERING
Never Water Your Plants Again
Most watering systems run on a timer. Ours runs on a plant. No timers, electricity, or apps needed. Set it up in 30 minutes with only a pair of scissors. Powering greenhouses and home gardens across Europe since 1965 and now available in the USA.
Soil Stays Evenly Moist
The cone opens the water line when soil dries, then stops as moisture returns.
Each Plant Decides
Every sensor works independently, so thirsty and shaded plants can share one system.
Rain Friendly
Unlike a timer, the system reacts to actual soil moisture after rain or cool weather.
Built to Expand
Add more sensors, tubes and drippers as your porch or garden grows.
Root-Zone Watering
Water goes where roots use it, helping reduce waste and surface evaporation.
Made for Travel
Set it up before a trip and come home to plants that kept drinking on demand.

Plant-Controlled Watering
How Blumat Drip Works
Water Pressure Powers the Supply
The system runs on gravity through a reservoir/rain barrel or connects to a hose spigot with a Blumat Pressure Reducer.
One Line Reaches Every Plant
An 8 mm supply tube runs from your water source past each plant in the system. At every plant, a sensor taps into the line — ready to release water only when its plant calls for it.
Dry Soil Creates Suction
The ceramic tip sits in the soil at root level. As the soil dries, it draws on the water sealed inside the ceramic — creating suction tension that pulls a diaphragm down inside the sensor.
The Valve Opens, Water Flows
The diaphragm opens a tiny valve in the 3 mm drip tube. Water flows from the pressurized supply line, through the sensor, straight to the plant — only the amount the soil is currently asking for.
Wet Soil Closes the Valve
Once the soil is moist again, suction tension releases. The diaphragm rises, pinching the drip tube shut. The plant waters itself again only when it dries out — without you ever lifting a finger.
