Blumat Drip Irrigation System 12 Pack - Automatic Plant Watering Kit for Garden, Patio, Hanging Baskets & Indoor Plants - Self-Watering Devices for Up to 12 Plants - Perfect for Vacation Care, Raised Beds & Container Gardening

Tropf Blumat Systems are the Future of Drip Irrigation Allowing each plant to determine its own irrigation schedule. How it works Each Tropf Blumat is filled with water and voided of air prior to being connected to a pressurized line (pressure from gravity-feed is adequate). The water inside the Blumat is in a completely sealed environment. The only exposure it has is through the pores in the ceramic cone. As soil surrounding the cone driesIt pulls on the moisture inside the cone through osmotic pressure. Since this is a sealed environment and the pressure cannot equalize, this pulls on a plastic diaphragm in the top of the Blumat.When the diaphragm is pulled down, it allows an irrigation tube running through the top of the valve of the Blumat to open and emit moisture. It does this very gradually.As the water is emitted through the Blumat, the moisture is gradually restored to the soil surrounding the porous ceramic.This relieves the pressure difference between the chamber inside the Blumat and the surrounding soil. This stops pulling on the diaphragm, and the diaphragm restores its former position of pinching the irrigation tubing shut.Allowing each plant to determine its own watering schedule. *The brown knob on top of each Tropf Blumat can be individually calibrated to specific plant species, strain/cultivar/varietal, or media.

Gravity Kit This kit comes with step by step instructions. To configure this system, all you need to complete this system is to provide your own reservoir. A 5 gallon bucket works. Confirm you have the ability to raise your reservoir near your plants. 12 Plant Irrigation Box Kit Irrigation for up to 12 Plants Designed to water areas up to 3.5 square meters, or 12 potted plants. Blumat systems can adjust to any plant type or desired moisture level. This specific kit comes with 5" carrots, which are better for smaller potted plants (10 gallons at most). This Kit Comes With: 12 Blumat carrots (5") 7 meters (23 feet) of 8mm tubing 1 tee splitter 1 elbow splitter 1 hose coupler 1 hose end-piece 1 rain barrel/gravity tank connector
