Grow container, a plug & play solution

A grow container is a shipping container converted into an urban farm. We use insulated containers for this that can be used both indoors and outdoors. The containers are fully equipped in our workshop for growing the crop you want. This fast plug & play solution offers great flexibility. You can start working on your urban farming project immediately after delivery and when the container needs to be moved, it can be transported on a truck to be used elsewhere.
The compactness of the containers makes them relatively easy and cheap to climatize. Shipping containers are available in various sizes and are high enough to accommodate multiple floors. Despite the small floor space, a considerable growing area can still be created.

The container is equipped with pallet racks of 80 cm deep and 250 cm high. This is where the plants grow. The length of the rack depends on the type of container desired. These racks are placed along the side walls of the container with a path of almost 70 cm wide between them. Depending on the type of crop you want to grow in the container, 1 or more levels can be installed in the racks. Ebb & flow trays are placed on these floors that are suitable for use in a drip or ebb & flow irrigation system. Another option would be to use special hydro growing containers in the racks as described below. The plants hang their roots directly in a water/nutrient solution and no substrate is used at all.

We install the type of grow lamp above each floor that is suitable for growing the desired crop.
The levels in the racks form “zones” for which the lighting intensity and the number of watering cycles can be adjusted separately.

The containers are available in 4 sizes:

Management

The control of the equipment in the container is fully automated. All settings and measured values ​​can be checked and adjusted via an app. Push notifications keep you informed of any malfunctions.
Measured values ​​such as temperature, humidity, CO2 levels, moisture levels and temperature values ​​of the substrate, PH, EC and temperature values ​​of the feed water are collected in a data logger and processed in graphs.
This way you have insight and control over the progress of your cultivation at all times and from any location in the world. The system can possibly be expanded with IP cameras so that you can also visually monitor your project.
If you give G-tools access to the installed app, we can remotely monitor and advise the progress of the cultivation.

The control software allows the following tasks to be set, measured and corrected:

-Lighting on and off times including sunrise and sunset simulation.
-Desired PAR/PPF (light intensity) values ​​of the lighting in the different zones.
-Temperature day and night.
-Humidity day and night
-Substrate temperature
-Substrate humidity
-Feed water temperature
-PH value of feed water
-EC value of feed water
-Water level water tank
-Smoke alarm
-Leakage detector
-Burglary detector

Heating/cooling

To maintain an even temperature, a Toshiba split unit is mounted in the container. These devices can heat, cool and dehumidify.
Cooling and heating capacity depend on the chosen container model and lighting.

Air extraction

Prima Klima Blue Line AC fan with matching Prima Klima Industry Line carbon filter.
Capacity depends on chosen container model and lighting.

Air intake

Prima Klima Blue Line AC fan
Capacity depends on chosen container model and lighting.
Includes swivel fans for internal air circulation.

Air humidification

Capacity depends on the chosen container model

Irrigation

Water tank with contents depending on chosen container model.
Drip irrigation or ebb & flow irrigation system
Supply pump with a capacity depending on the chosen container model
Peristaltic dosing pumps for adding nutrition and PH correctors

Container project Weesp

For several years now, our workshop in Weesp has had a 10-foot sea container that we have converted into a mini urban farm. Over time we have grown a wide variety of leafy vegetables, herbs, sprouts and edible flowers here. Too many to mention! The use and continuous improvement of the container has yielded a lot of knowledge and experience. In addition, we have hardly spent any money at the greengrocer during all that time.

To keep the temperature constant, the container is equipped with a split unit and insulated with PIR panels. The split unit can both cool and heat. This allows you to always set the perfect temperature for healthy growth. Theoretically, this means that the container can be placed at any location where there is a water and electricity connection.

Racks of 4 floors have been placed along the walls of the container. 16 grow trays with lids are placed inside. A layer of water with nutrition is pumped around in the grow trays of 70 x 140 cm. The plants themselves are placed in net cups that are placed in holes in the lids. The roots grow directly in the recirculating water/nutrient solution.

grow container

The floor surface of ​​this container is only 7 m2. With a cultivation system of 4 floors, no less than 16 m2 of grow surface has been realized. The water tanks, the split unit and a path for working are all built inside the container of (l x w x h): 2.99 x 2.44 x 2.59 meters.
In addition to water and nutrition, plants need light. This comes from 48 x 42 Watt LED grow lights that are mounted against the bottom of each shelve of the grow racks.
The LED lamps used here are suitable for growing leafy vegetables and herbs.
