Yagur Hydroponic Agriculture 3
6,000 sqm of Hydroponic Deep Water Floating Raft Culture (DWC) greenhouse
Each production pool is 30 meters length and 6 meters width. Each raft contains five lettuce plants
Production pool water volume: 18-20 m³
Growing cycle – 20 days
Filtoflex Nano bubbles system was located at the head of the production pool, generating Nano air bubbles at high intensity, creating enriched water at a range of 1.5 m³ per hour
LocationYagur Hydroponic greenhouses, Israel
Average Temperature of 23°C
The growth cycle was in July, a month with higher solar radiation
Enriched fertigation water with Nano air bubbles increased the average the fresh weight of the lettuce by 43% or alternatively it shortened the growing cycle by four days, thereby increasing the number of harvests per year.
The amount of fertilizer was reduced by 10%
Based on the above experiment, there is a saving of 3-4 growth days per cycle, which represents two additional growing cycles per year.
Based on grower cost and profit conditions, the ROI is 6 months
