Deep water cultivation of lettuce

Every grower's goal is to maximize yield and achieve a high quality crop. This should be achieved with the minimal use of raw materials to save costs and increase sustainability. For short cycle crops such as lettuce, herbs and cabbage, hydroponic growing is the way to go!

Cultivation on deep water or in the open field?

The main benefit of growing hydroponically in comparison to the open field is that production takes place in a more safe and controlled environment. Cultivation in deep water causes less plant loss and results in a clean product without any dirt. Since all plants have the same water intake a uniform quality of the crop is achieved.

Another important benefit is the increased amount of cultivation cycles which can be produced in a year. This boosts the total yield immensely. And because the product is floating the complete system can be automated. This enables growers to scale up and cultivate at a very cost efficient rate.

From 70 to 7 liters per crop!

Sounds like this cultivation process needs a lot of water, right? Well, it doesn't. The whole system needs roughly 7 liters in comparison to 70 liters per head in the open field.

Growing in a controlled environment also saves fertilizers because the fertilizer stays in the water system and isn't being drained out in the field as occurs with the traditional growing method. In the hydroponics system the use of pesticides can be limited, because the environment can be controlled much better. Different disease hazards can be excluded from the closed system, which helps you to bring back your use of chemicals. This improves the sustainability of the cultivation process. Besides, no more mechanical soil cultivation is required which may be the most attractive benefit of them all.

Food safety

The demand for food safe products is increasing at a fast rate. All over the world food safety is a top priority. This means stricter requirements regarding the production and handling of fresh produce. Traceability is becoming more and more the standard and solutions that enhance food safety get a lot of attention worldwide. Growing short cycle crops on deep water is one of the ways to ensure the safe production of fresh produce while guaranteeing high yields and less usage of raw materials.

Viscon Hydroponics

Viscon Hydroponics delivers turn-key projects for cultivating short cycle crops, like herbs, cabbage and lettuce, that can be grown on a deep water culture. This enables the grower to minimalize raw materials such as fertilizer and water, while increasing the weight per head and the number of cultivation cycles. Different cultivation materials can be used as a medium, which includes Oasis, Rockwool and Foam. The system consists of four phases:

1. Growing the young plants

Young plant production is one of the most vital parts of a solid hydroponic system.

2. Production on deep water

The design of the tall floats makes for a system that needs little handling, with as little movements as necessary.

3. Ergonomic harvesting

There are two ways to harvest the crop. Fully automated in the packhouse or semi-automated in the greenhouse. The videos below show all the details of each harvesting method.

4. Retail-ready packaging

The product can be packed with the grow cup attached for better shelf life. It can also be cut directly from the grow cup to be flow packed for a ready to use product.
