The Department of Agriculture recently launched the “Plant, Plant, Plant” National Movement encouraging everyone to grow their own food to address food sufficiency in the midst of the CoViD-19 crisis. However, though the seeds are readily available, one concern is the limited or no space for planting especially those in the urban areas. To address this, aside from promoting the use of hydroponics, the CLSU through the College of Engineering (CEn) introduces the vertical farming system (VFS) using root zone cooling. This technology, according to Engr. Christopher Pascual, a CEn faculty researcher, uses ground heat exchanger for root zone cooling of vertically-grown crops in a hot weather condition. The greenhouse established for technology demonstration at CLSU has a 72 square meters area where it can accommodate 88 towers. Each tower can grow 70 leafy vegetables as well as herbs where about 6,000 plants can be harvested. The unit, which includes the greenhouse and the system, could cost Php350,000.00. This can generate a gross income of Php300,000.00 a year with up to 14 times of cropping cycle.
The technology is already registered in the Intellectual Property Office under Industrial Design. If you have any queries regarding the technology, you may direct it to Engr. Pascual at 0917-874 1150. For more technology feature, visit the CLSU website at https://clsu.edu.ph.
