After choosing a planting location, the next thing you need to do is design a trellis to plant trees. Hydroponic vegetable planters must be based on the area and actual conditions of the planting site. 

Some types of hydroponic vegetable growing rigs that are very popular today are: 

Cascade truss design type 

Cascade trellises are the most common type of design when growing hydroponic vegetables. This design is best suited for houses with corrugated iron roofs but still ensures that the light element provides enough every day for the tree. 

The sun shines obliquely evenly on the floors to help the plant receive the maximum amount of incoming light. For each truss that looks like this there are usually 2-3 floors, each floor has 3-5 pipes. 

A-shaped semi-rig design 

The A-line anti-truss design is suitable for houses with high walls. The truss is built close to the balcony or wall and faces outward to receive natural light. 

For houses with blocked balconies or high fences on the side, it is very suitable for this type of A-truss. You can lack 2 semi-A-shaped trusses on both sides that will create a very beautiful airy garden space. 

Flat truss design 

The flat truss design is suitable for terrace areas and uncovered balconies. The width of the truss is usually from 1m – 1.5m, on each such truss there are about 8-10 hydroponic tubes, the length of each tube depends on the space area, usually from 3-6m long.

With a flat truss design, you can design 1-2 trusses. The distance from the upper trellis to the lower trellis is about 45-60cm to ensure that when large vegetable plants are not blocked from light by the upper floor or grow thick together..  

Each type of truss has its own advantages and disadvantages. You should consider to choose the type of trellis that best suits the idea and location of the planting.
