Designed specifically for potted plants, this pressure compensating drip emitter has consistent flow rate over a wide range of pressures. The BG-050, .5 GPH is excellent drip emitter used with one of our multi-outlet adapters for drip irrigation of potted flowers or vegetables in greenhouse benches. This line of PC drip emitters can be used with single, double or four outlet press-fit adapters, micro tubing with .117 to .125 ID and a pot stake for support to deliver the small amounts of water needed for high production of potted plants in greenhouse applications. One of the main features of this PC drip emitter is its capability to open at a pressure of 4.3 PSI and to close at a pressure of 2.9 PSI, saving water and nutrients. Use these agriculture grade drip emitters to ensure even and consistent flow of water from each drip emitter along the line, regardless of water pressure fluctuations related to elevations along the drip laterals. This range of PC drip emitters has outstanding resistance to clogging and are easy to use and install. All our PC drip emitters have a self-flushing mechanism and are manufactured by some of the best names in the industry with superior materials for a long life.

Designed for greenhouse applications, this line of PC drip emitters, accessories and pre cut micro tubing of various lengths is used for potted plants in greenhouse applications.
Using drip irrigation in greenhouses and applying water directly to the pots and under the plant canopies has many benefits including:
• The plant remains dry helping to minimize foliage pathogens.
• Pesticides applied to the foliage are not washed off, reducing the need for spraying.
• Injecting expensive nutrients through the drip system can minimize and save nutrients.
• Use of drip irrigation can allow for pulse watering, by applying water several times during a drying cycle instead of just once.
Overall, using drip irrigation in greenhouses can help lower production costs and increase efficiency and uniformity, aiding in a successful growing season.
How drip irrigation works with potted plants in greenhouse applications:
Using drip irrigation in an automated system can help deliver water to each individual potted plant using The Drip Store’s multi-outlet PC emitters with two or four outlets connected to micro tubing in various lengths. The micro tubing is secured to the pot with a stake that has a flow labyrinth, which assures that regardless of the length of micro tubing from each outlet, the flow to each pot will be the same. This advanced system utilizes high uniformity, high performance components to assure each plant receives the same amount of water with high uniformity of 95 to 98 percent.
Uniformity and lower maintenance:
With higher uniformity over a wide range of pressures, the pressure compensating drip emitters offer many advantages in site preservation and maintenance, such as even uniformity over a longer lateral run with smaller size valves due to a smaller sized delivery system, and resistance to clogging due to the water passage design.
Water movement in the soil:
When using drip emitters it is important to select the correct flow rate in order to achieve the right wetted pattern shape. In sandy soil, water tends to drain quickly (gravitational force) with little lateral movement, so applying a higher flow rate over a given time period will produce a wider pattern. Using point source irrigation with .5 GPH drip emitters for one hour will provide a smaller wetted area then using 1 GPH for the same time, due to the soil characteristics.
About drip irrigation:
Drip irrigation is the slow application of water directly to the plants' root zones in a predetermined pattern. Drip irrigation can be used to maintain optimum moisture level in the soil at all times, resulting in less water lost to the sun and the wind. No water is wasted on non-growth areas, and the root zone is maintained at its ideal moisture level, combining the proper balance of water and air for a very efficient irrigation system.
To water a diverse selection of plant sizes such as trees, shrubs, bulbs and perennials, the option below can be utilized:
· Suggested number of drippers per plant:
o Vines with spacing of 6’- 8’ use 1 GPH per vine or 2, .5 GPH drip emitters spaced on each side of the vine with 8” to 12” between the drip emitters.
o Plants in close spacing: use a 1-GPH dripper every 10" to 12".
o Small plants up to 2 feet high spaced a few feet apart: use one 1-GPH dripper per plant.
o Plants 2' to 3' high: use 2 1-GPH drippers per plant spaced 12" apart.
o Plants 3' to 5' high: use 3 to 4 1-GPH drippers per plant, spaced 12" apart or loop the drip hose around the plant and insert the drippers every 12".
o Plant 5' to 7' high: use 4 to 6 1-GPH drippers per plant, spaced 12" apart or loop the drip hose around the plant with the drippers spaced 12” apart.
How much time to water: Turn the water on for 45 minutes to 1 hour every two to three days, depending on the drip emitter flow rate, your location and the soil type. After a week or two check the soil and the health of the plants, and adjust the irrigation time as needed. If you have an irrigation controller and you need to add more time, adjust the time on the controller or program the controller with additional start-times.
Note: Katif dripper models D043, D044 and D045 require the use of a punch with a 4mm tip.
