Blumat: the automatic watering system revolutionizing your indoor grow
Blumat automatic watering systems put an end to the daily watering struggles in indoor cultivation. These Austrian devices operate by capillarity and pressure, without electricity or complicated programming. The ceramic sensor detects the substrate's moisture and releases water only when the plant needs it.
Why choose a Blumat system for your growing space
Frankly, once you've tried Blumat, there's no going back. The principle is brilliant: the ceramic sensor soaks up water and maintains constant pressure. When the substrate dries, the pressure decreases, and water flows out automatically. No temperamental timers, no pumps failing at the wrong moment.
The BLUMAT Automatic Watering System - 40 Plants - 10M x 8mm can automate up to 40 pots with tool-free installation in less than an hour. Water savings are impressive: each plant receives exactly what it needs, no more, no less.
To expand an existing setup, the Blumat - Carrot Extension X2 for TROPF system integrate perfectly with all necessary fittings and hoses. Distribution remains uniform even over large areas.
How to choose your Blumat system
It all depends on your setup. For 1 to 6 plants, Classic kits with a gravity reservoir are more than sufficient. Beyond that, opt for Tropf systems, which support up to 40 watering points on a single line.
Pot size also matters: standard sensors are suitable for containers from 3 to 20 liters. For larger containers, XL versions with a range of 30-40 cm are more appropriate. The flow rate can be finely adjusted using the integrated adjustment screw.
In terms of pressure, Blumat operates between 0.1 and 4 bars. If you connect directly to the water supply (often 3-6 bars), a pressure reducer becomes essential to prevent overflows.
Frequently Asked Questions
How to choose between Blumat Classic and the XL version for my indoor plants?
The Classic effectively covers a 15-20 cm radius around the sensor, perfect for 3 to 15-liter pots. The XL version extends this range to 30-40 cm and is better suited for large containers of 20 liters and more. In indoor growing, the Classic is sufficient in 90% of cases because giant pots are rarely used. The XL becomes interesting for mother plants or coco setups with large volumes.
How to correctly install a Tropf-Blumat sensor in an indoor pot?
Plant the ceramic sensor in the center of the pot, halfway up the substrate, never against the sides. Fill it with water from the top until it overflows, then screw the cap on firmly. Wait 15-20 minutes for the ceramic to fully saturate before connecting the hose. Place the reservoir or water source 50 cm to 1 meter above the pot to create the necessary gravity pressure.
How to adjust the Blumat sensor to water just enough without overwatering?
Start by screwing the adjustment knob all the way in, then unscrew it a quarter turn. Observe for 24-48 hours: if the substrate remains too dry, unscrew another eighth of a turn. If there is overwatering, screw it in slightly. The perfect adjustment is achieved through small, successive adjustments. Once stable, the system automatically maintains optimal humidity without intervention.
Do I need a pressure reducer if I connect Blumat directly to a tap?
Absolutely, it's even crucial. Household water pressure varies between 3 and 6 bars, while Blumat operates between 0.1 and a maximum of 4 bars. Without a reducer, you risk constant overflows and improper sensor function. Invest in an adjustable 0-4 bar reducer; it costs 20-30€ and prevents many headaches. Some Blumat kits already include it.
How to maintain Blumat sensors so they last a long time in indoor growing?
Clean the ceramic sensors every 2-3 months with a soft brush and clear water to remove limescale deposits. Avoid chemical products that could clog the pores. Replace the water in the sensors regularly, especially if it stagnates for a long time. At the end of the cycle, disassemble everything, rinse thoroughly, and store dry. With this minimal maintenance, Blumat sensors easily last 3-5 years of intensive use.
