Medium Kit Our medium kits are designed to water areas up to 3.5 square meters, or 12 potted plants. This kit is nearly identical to our deluxe medium kit, however, it comes with a 5-gallon gravity tank with thru-hulls already installed. i.e. This kit includes everything you need to create your very own electricity-free, gravity-fed system. Blumat systems can adjust to any plant type or desired moisture level. Slow Watering The water is released slowly and in doses. Consequently, plants always receive tempered water and healthy and lush growth is the result. Gravity System This specific kit comes with 5" carrots, which are better for smaller potted plants (10 gallons at most). If you have large plants (10+ gallon pots), we recommend using 9" carrots, or Maxis, to get water deep into the soil. No complex programming No batteries Water is released slowly and in doses Example of a raised gravity system Water your flowers, plants and vegetables Tropf-Blumat is an automatic watering system for plants all around the house.

Automatic Irrigation for 4'x8' raised bed Items that come with this Kit Automatically water a 4' x 8' raised bed with just a rain barrel or water reservoir. The reservoir should be at least 3' above ground level. Optional pressure regulator attaches to garden hose or faucet and can provide enough water for up to 500 Blumat Carrots. This Kit Includes: 8 - Blumat Carrot outdoor sensors & 16 - Distribution Drippers 1 - rain barrel/gravity tank connector 32.8' tubbing (10m) 20' of 3mm tube 1 - Blumat Shut Off Valve 1 - Blumat Quick connect for 8 mm tube & 1 - Quick Connect for 3mm 4 - Blumat Tees & 4 - Distribution Dripper Ends 5 - Blumat Elbows Step by Step on How A Tropf Blumat Works 1. A valve within the Blumat reacts by sub pressure. This sub pressure, the so-called suction tension, develops in dry soil. The dry soil conducts a suction which develops tension within the Tropf-Blumat.2. Then a valve is pulled downwards, allowing the passage of water ...3. and the slow drip of water begins.4. Likewise, in reverse, when the soil has reached its peak moisture, to the level of moisture at which the Blumat cone was installed in5. The sub pressure in the sensor causes the water to be sucked back into the cone, and the valve within the Blumat returns to its original position, then squeezes the drip tube closed with a rod, and the passage of water is stopped.6. This allows for the slow delivery of water at the plant’s preferred rate, allowing each plant to determine its own irrigation schedule. The Tropf Blumat self-watering system functions automatically. As the soil dries, a vacuum and hydro-static pressure, coupled with a spring-loaded gating mechanism, pulls water from the main line. When the soil is sufficiently moist, pressures equalize, and the Tropf Blumat automatically stops taking in water. Perfect for landscapers and home gardeners. This kit includes forty 5" carrots and all the parts required for a gravity-fed system. Reservoirs should be at least 3' above ground-level. The Tropf Blumat system is great for watering balcony boxes, planters, hanging baskets, and row crops. It fulfills the needs of the plants on an individual basis, regardless of their location, light levels, or plant type. Our systems save your plants from excessive and improper watering.
