This comes with a green emitter for 0.5 GPH (1.9LPH). 

The FloraFlex 1-Way Micro Dripper Stake Assembly is the perfect solution for precise and efficient plant watering. 

Looking for netafim drippers? . 

• Efficient Watering: The FloraFlex 1-Way Micro Dripper Stake Assembly provides precise watering to your plants, ensuring they receive the right amount of water for optimal growth.

• Pressure Compensating Emitter: The included pressure compensating emitter ensures consistent water distribution, even in areas with varying water pressure.

• Self-Cleaning Lateral Path: The torturous path design of the microtube ensures that the assembly remains clear of debris, reducing the risk of clogging and ensuring reliable performance.

• Versatile PSI Range: The recommended PSI range for optimal performance is between 25-35, with a maximum recommended PSI of 50. This allows for flexibility in different watering setups.

• Compatible with Various Pump Systems: The FloraFlex 1-Way Micro Dripper Stake Assembly is compatible with pump systems that have a max head height/total lift of at least 40 feet, meeting the minimum pressure requirements.

Water Pressure with Pressure Compensating Emitters

Theoretically between the stated operating pressure range of an emitter, the volume of water coming out should be the same. The diaphragm inside the emitter opens when a pressure is reached and allows water to pass.

However, in practical terms even within the specified operating pressure range, the volume of water output from a Pressure-Compensating Drip Irrigation (PCJ) system can vary due to factors like emitter design, small pressure fluctuations, and maintenance conditions. Additionally, if emitters are clogged or not maintained properly, they may not provide the intended flow rate, leading to uneven watering.

Key Point on Clogging: Clogging is a common issue in drip irrigation systems, where debris or mineral deposits build up in emitters. This blockage restricts water flow, causing some plants to receive less water than they need, which can stress them or lead to uneven growth. However a partially clogged dripper may still work at higher pressure but restrict flow at lower pressure. ie the higher pressure will blast through the partial clog drippers. 

To prevent clogging, it's crucial to regularly clean the emitters and use water filtration systems such as the to ensure your irrigation system runs efficiently and your plants remain healthy. You can also use something like, with your nutrients. 

Suggested High Pressure Pumps

The most common operating range is 20-40 psi / 1.4-2.8 bar . You MAY be able to get away with less pressure especially in a small setup 4 plants in a 1m tent where the reservoir is very close (and the pipework is not doing up down left right and loop-da-loops). To summarise some options for you

• - 0.8 bar (not optimum but for the cost you may be able to get away with it in a small setup)
  

• - 3 bar
  

• - 3 bar
  

• - whatever you want but must be used in conjunction with and a controller like the
  

For the Aquaking and Clarke pump, you will need to join on to Floraflex tubing or similar LDPE material pipe work. In which case you  may also need a Floraflex hole puncher This will make light work of punching holes in. If there was ever a tool that you will be thankful for, its this bad boy

Also consider getting this Digital Time-r for your pump to set your feed schedules. This one goes down to the second and is way way way (!!) easier to setup. Please believe.

Considerations For Floraflex Drippers

If you have a large system with 10+ / pots that are far apart, then we suggest you use the Floraflex emitter 0.5GPH (punch holes in your drop line and stab these things into it!).

 This means water will only come out of the drippers once a certain amount of pressure has built up in the system - this ensures even watering across the entire system...otherwise, the ones closest to the pump will be fed first and the one at the back will get the least watering!

You'll also need to install a Floraflex Micro-Drip Lateral Flush Valve (use a Floraflex 16/17mm Pipe Fitting T  piece & a Floraflex 16/17mm mm Pipe Fitting to 3-4" Male Adaptor to connect it), check out the diagram on the top spin drippers product page for more info.
