What is the best way to monitor my irrigation and fertilization?

There are two valuable ways to monitor irrigation and fertilization.Drainage: Drainage helps ensure that you irrigate the right volume and that you don't accumulate salt in your substrate, which could harm your plants. Carrying out chemical analysis of drainage and irrigation water at least once every two weeks will help to expose an unbalanced process.Soil moisture sensors will help you continually monitor water content in your substrate, especially in the greenhouse watering system. Once you're familiar with your crop and substrate, you can adjust irrigation and fertilization schedules for optimum yield.

What are the benefits of Compensated Non-Leakage (CNL) drippers?

Irrigation of soilless media is done through short irrigation pulses. CNL drippers help you increase fertigation uniformity by preventing system drainage and thus eliminating the refilling time of the system. That means all the drippers start and stop at the same time every irrigation cycle, guaranteeing equal quantities of water and fertilizers to all plants.

Greenhouse Watering System

Since pioneering drip irrigation in 1965, Netafim has become the global leader in greenhouse watering systems, and it’s one of our unique strengths. The majority of high-end greenhouses all over the world are installed with Netafim drippers and irrigation systems.

Greenhouse Water Systems From the People Who Invented Them

Water is a crucial factor in the success of any grower solutions greenhouse. Given the limited soil buffer, greenhouse irrigation systems and fertigation systems are vital for the quality and yield of your crop. At Netafim, we are world leaders in this field, offering flexible greenhouse irrigation and fertigation systems that deliver water and nutrients according to a plant's specific needs:

Feeding Your Plants Precisely What They Need

Your plants will reward you with healthy crops and high-quality yields when grown in ideal conditions. Feeding plants the most optimal way is crucial in creating optimal crop results. Therefore, we've developed the fertigation (fertilizers + irrigation) technique - using drip as a delivery system for nutrients.

Fertigation is all about quantities, nutrient combinations, and precise timing. Precision fertigation is the optimal root-zone management tool, delivering just the right mix of water and nutrients directly to the roots of each plant, according to your crop development cycles.

Precision fertigation optimizes your fertilizer investment by letting you change dosages on demand, for instance, in response to setbacks like market fluctuations and weather changes.

When dealing with soilless grower solutions greenhouse cultivation, precision and homogeneity are crucial. Soilless substrates have an insufficient buffer capacity (depending on substrate and container characters), so water and nutrients must be delivered to the plants in small doses and with very high accuracy through the use of the greenhouse watering system. To do this, we've created Netafim's industry-leading multi-channel dosing machines.

Saving Water Through Disinfection

In grower solutions greenhouse, we constantly recycle about 20-30% of the water by disinfecting it and mixing it with fresh water from an external source. This reduces water use and fertilizer use, as recycled water retains nutrients from one cycle to the next.

Due to their high efficiency, we use various disinfection techniques in our greenhouse watering systems, including UV, Ozone, and leading micro-filtration methods used in the medical sector.

Our water disinfection solutions are simple to use and, once installed, require little maintenance. You can also select different doses depending on your crop and the pathogens you’re guarding against.

Water recycling via grower solutions greenhouse is cost-effective and highly sustainable, as reusing drain water prevents land and water contamination.

Reverse Osmosis Systems

Reverse Osmosis (RO) grower solutions greenhouse irrigation systems enable the desalination and filtration of water to provide water for your irrigation system. These systems extract salts, organic substances, and other dissolved particles, along with bacteria and viruses. Our Reverse Osmosis systems are tailor-designed – each made to answer the specific needs of your crop and the condition of your water source.

Hydroponic Greenhouse Systems

As a leader in greenhouse irrigation systems, we also offer a range of hydroponic systems, including NFT and ‘Ebb n Flood’:

NFT Systems

Nutrient Film Technique (NFT) is a hydroponic system that is resource- and labor-efficient. It offers a significant saving in terms of space, water, fertilizers, and pesticides – and is currently the preferred method for growing lettuces and herbs worldwide. With the implementation of a grower solutions greenhouse watering system, the NFT method becomes even more efficient.

In NFT, plants are grown in plastic gullies. A solution of fresh oxygenated water and minerals is pumped to the high end of the gully and flows to the low end where it's collected in a reservoir.

The Netafim NMC controller keeps the plant roots in the gully moist but not waterlogged, and provides them with the ideal blend of water, minerals and oxygen. We also use additional systems such as filtration, sanitation and chilling (if required) to keep the running water clean and cool.

NFT technology helps you grow premium quality produce all year round. With its minimum inputs of water, fertilizer and pesticides, it's also a cost efficient, sustainable growing method.

Netafim NFT Systems are in-house designed and manufactured to guarantee quality, reliability and performance.

Ebb n Flood System

‘Ebb and Flood’ (or ‘Flood and Drain’) is a different greenhouse watering system involving the periodic flooding and draining of the nutrient solution.

The system works in two phases: water and nutrients flow through the growing areas, flooding over the plants' roots. The water then drains back to the reservoir. The cycle repeats continuously, hence their name.

At Netafim we deliver Ebb n Flood systems on a specialized concrete floor, specially designed covers or on tray-tables – each option is designed to allow water to flood and drain efficiently and precisely without any loss.

A BREAKTHROUGH IN EBB N FLOOD 2.0

Netafim is proud to present a leading breakthrough in grower solutions greenhouse irrigation systems, currently being pioneered in highly sophisticated cannabis greenhouse projects. A unique combination of Ebb n Flood together with Netafim Drip Irrigation is leading to revolutionary results in crop quality and control over plant nutrition.
