A growbag spacer is a structure or device designed to maintain an adequate and constant distance between substrate bags used in container growing systems, such as growbags. These spacers are usually made of sturdy materials, such as plastic or metal, and are placed between the substrate bags and the soil.
Sometimes, if the drainage produced by the system needs to be reused or redirected, it is usually placed between the drainage channel and the bag, in order to avoid puddling.
The main function of the spacers is to provide a number of benefits to the cultivation system, such as:
- Improved ventilation: Spacers allow air to circulate freely between the substrate bags, which helps prevent problems related to excessive humidity and lack of air circulation, such as the development of fungal diseases.
- They avoid contact with the ground: By elevating the substrate bags, the spacers prevent plant roots from coming out of the drainage holes in the substrate bags and prevent them from coming into direct contact with the soil. This is especially useful in areas where the soil may be contaminated or unsuitable for growing.
- Reduction of waterlogging: By elevating the substrate bags, we avoid areas that can cause waterlogging, especially in compacted soils or in the drainage channels themselves, which can create the ideal conditions for the development of fungal diseases.
- They facilitate handling and access to the plants: By raising the substrate bags, the spacers make plant care and harvesting easier, as less bending down is required and contact with the ground is avoided.
- Facilitate maintenance and cleaning: The bags are separated from the soil and/or the drainage channel, allowing maintenance and cleaning to be carried out quickly, even without having to dismantle the cultivation system.
In summary, a grow bag spacer is an important tool in the substrate bag cultivation technique, as it contributes to improving the growing environment, resource efficiency and access to the plants. This makes it a valuable option for growers looking to optimise their hydroponic growing systems.
